WEBVTT 00:00.000 --> 00:12.000 Hi, everyone, so I'm here to talk about Fed, yes, we call it Fed, not F3D, please. 00:12.000 --> 00:13.000 Remember that? 00:13.000 --> 00:21.000 So Fed is a fast and minimalist 3D viewer, but I'm here as a president of Fed App Foundation, 00:21.000 --> 00:24.000 which is a non-profit that we created for the project. 00:24.000 --> 00:27.000 I won't talk too much about it, but if you have a question about, 00:27.000 --> 00:31.000 how we did the non-profit and everything, that's very happy to answer. 00:31.000 --> 00:35.000 So, yeah, I'm mature, I'm a mentor and co-creator of Fed, 00:35.000 --> 00:39.000 in the room there is a so-micro, which is also a mentor and co-creator of Fed. 00:39.000 --> 00:45.000 We both also have their jobs, this is something we do on a free time. 00:45.000 --> 00:50.000 I do want to mention that we have a funding that let us do this kind of activities, 00:50.000 --> 00:51.000 as going to first them. 00:51.000 --> 00:54.000 This funding is provided by NNLets and GIS-0. 00:54.000 --> 00:56.000 So you definitely want to check them out, 00:56.000 --> 00:58.000 if this is something you're looking for. 01:00.000 --> 01:03.000 Okay, so let's do a quick test in the room. 01:03.000 --> 01:06.000 So please, once you're in and keep it waste, 01:06.000 --> 01:09.000 if you have GLTF file on your computer. 01:09.000 --> 01:10.000 Okay? 01:10.000 --> 01:11.000 Got a few? 01:11.000 --> 01:13.000 A fix? 01:13.000 --> 01:14.000 Okay? 01:14.000 --> 01:15.000 UST? 01:15.000 --> 01:17.000 And that's a match? 01:17.000 --> 01:18.000 A STL? 01:18.000 --> 01:19.000 Okay? 01:19.000 --> 01:21.000 Oh, yes, that's a more people. 01:21.000 --> 01:22.000 OBGee? 01:22.000 --> 01:23.000 Okay? 01:23.000 --> 01:24.000 Almost everyone? 01:24.000 --> 01:25.000 Step file? 01:25.000 --> 01:26.000 Yeah? 01:26.000 --> 01:27.000 Alambic? 01:27.000 --> 01:28.000 ADC file? 01:28.000 --> 01:29.000 Oh, not that much? 01:29.000 --> 01:30.000 Yeah? 01:30.000 --> 01:31.000 OBGee? 01:31.000 --> 01:32.000 Nobody? 01:32.000 --> 01:33.000 Okay? 01:33.000 --> 01:34.000 We can remove that. 01:34.000 --> 01:36.000 Do you do Gaussian splatting? 01:36.000 --> 01:38.000 Oh, there's one guy. 01:38.000 --> 01:39.000 Nice. 01:39.000 --> 01:43.000 Then I would say everyone is if we need Fed, 01:43.000 --> 01:47.000 because Fed will help you with all of that. 01:47.000 --> 01:49.000 So what is it? 01:49.000 --> 01:51.000 Fed is a fast and minimalist, 01:51.000 --> 01:53.000 really if you were, it's obviously open source. 01:53.000 --> 01:56.000 It's posted on GitHub. 01:56.000 --> 01:58.000 It's a community driven. 01:58.000 --> 02:02.000 There is no company behind it currently. 02:02.000 --> 02:05.000 So we have a very active community of contributors. 02:05.000 --> 02:07.000 I won't talk much about that, 02:07.000 --> 02:09.000 but if we have questions about our community, 02:09.000 --> 02:10.000 I'm very happy to answer them. 02:10.000 --> 02:12.000 We will use every three months, 02:12.000 --> 02:15.000 and we have a very nice website with which 02:15.000 --> 02:17.000 I will share you with our QR code at the end. 02:17.000 --> 02:18.000 Okay? 02:18.000 --> 02:19.000 So what can you do? 02:20.000 --> 02:21.000 What can you do with Fed? 02:21.000 --> 02:25.000 So let's say you just want to quickly visualize a solidified. 02:25.000 --> 02:30.000 So if you usually what you need to do is you go online to 02:30.000 --> 02:34.000 3D viewer or you open Blender, which is very nice software, 02:34.000 --> 02:35.000 but quite big. 02:35.000 --> 02:36.000 You can do the same with my club. 02:36.000 --> 02:38.000 Or you can even go to the dark side and open, 02:38.000 --> 02:41.000 I don't know, my course of 3D viewer, 02:41.000 --> 02:43.000 or any kind of freeware with some others. 02:43.000 --> 02:44.000 That's not everywhere. 02:44.000 --> 02:47.000 Well, of course, you can use Fed. 02:47.000 --> 02:50.000 You can just double click on any of your 3D file, 02:50.000 --> 02:51.000 and you just open it. 02:51.000 --> 02:52.000 That's it. 02:52.000 --> 02:53.000 That's a viewer. 02:53.000 --> 02:55.000 That's what it does. 02:55.000 --> 02:58.000 Or you can use the command line of course, 02:58.000 --> 03:00.000 Fed your file, and that's it. 03:00.000 --> 03:01.000 You open it. 03:01.000 --> 03:05.000 Let's say you want to generate some names for your 3D files. 03:05.000 --> 03:06.000 You're in your file. 03:06.000 --> 03:08.000 Your file browser, your file explorer. 03:08.000 --> 03:10.000 Just want you have so many files. 03:10.000 --> 03:12.000 You're a bit lost, 03:12.000 --> 03:14.000 because you're looking for files and naming. 03:14.000 --> 03:16.000 Maybe it's not perfect. 03:17.000 --> 03:19.000 So there is some solutions out there. 03:19.000 --> 03:20.000 As they have some, 03:20.000 --> 03:23.000 as being existing for more than 10 years now, 03:23.000 --> 03:25.000 there is another project called space thumbnail. 03:25.000 --> 03:27.000 So it's maintained. 03:27.000 --> 03:29.000 But there are all other limitations. 03:29.000 --> 03:34.000 And here Fed is very, very good solution here. 03:34.000 --> 03:38.000 You're basically able to generate thumbnails for all your files, 03:38.000 --> 03:41.000 all the files and machines, all the formats and machines. 03:41.000 --> 03:44.000 In natively, in most Linux distribution, 03:44.000 --> 03:48.000 and it's also natively supported on Windows. 03:48.000 --> 03:50.000 We don't support my quest. 03:50.000 --> 03:52.000 Sorry. 03:52.000 --> 03:55.000 Let's say you want to quickly open CAD file. 03:55.000 --> 03:59.000 Well, you can use free code, of course. 03:59.000 --> 04:03.000 But it's very nice, but also very big software to open. 04:03.000 --> 04:06.000 Or there is a lot of property sites, 04:06.000 --> 04:08.000 a lot of different software. 04:08.000 --> 04:10.000 Many of them, actually. 04:10.000 --> 04:12.000 But you can do that with Fed as well. 04:12.000 --> 04:14.000 Yes, it's the same idea. 04:14.000 --> 04:16.000 You just double click on the file, or use a command line, 04:16.000 --> 04:17.000 and we just open. 04:17.000 --> 04:20.000 Of course, that's for step file, 04:20.000 --> 04:22.000 IDS file, that's the format with support, 04:22.000 --> 04:24.000 currently for CAD. 04:24.000 --> 04:27.000 Okay, let's go a bit further. 04:27.000 --> 04:28.000 Let's set. 04:28.000 --> 04:32.000 You want to integrate the 3D modeling of a 3D model into a script. 04:32.000 --> 04:33.000 Can you do that? 04:33.000 --> 04:36.000 Let's say you have your Python script, 04:36.000 --> 04:40.000 that we generate a JLTF file from a Python libraries, 04:40.000 --> 04:41.000 and let's do that. 04:41.000 --> 04:44.000 And you want just to create a PNG file 04:44.000 --> 04:45.000 from this JLTF file, 04:45.000 --> 04:48.000 because you want to put it somewhere as this image 04:48.000 --> 04:50.000 is because you want to upload to a website, 04:50.000 --> 04:53.000 where you have to have a PNG associated to your file. 04:53.000 --> 04:56.000 But you could write a custom Python script, 04:56.000 --> 04:58.000 that we're actually with the JLTF file, 04:58.000 --> 05:00.000 and then when they're retusing much won't, 05:00.000 --> 05:04.000 or you create your own C++ program in using OpenGL, 05:04.000 --> 05:06.000 and do the rendering, and stuff like that. 05:06.000 --> 05:09.000 But of course, you will not do that. 05:09.000 --> 05:12.000 You can just use FAD, because it's a common line oriented, 05:12.000 --> 05:14.000 so you can just dash dash output, 05:14.000 --> 05:17.000 and here you go, you got your PNG file, 05:17.000 --> 05:21.000 and we recently added animation support in that context. 05:21.000 --> 05:24.000 So that means that if you have an animated file, 05:24.000 --> 05:26.000 that you're open in FAD, 05:26.000 --> 05:29.000 and you output with this specific syntax here, 05:29.000 --> 05:32.000 you will be able to generate hundreds of PNGs, 05:32.000 --> 05:37.000 and then convert that using FFMBG to a M before. 05:37.000 --> 05:42.000 Yes, or what you can even do if you want to go deeper 05:42.000 --> 05:45.000 into the scripting phase, you can use Python values. 05:45.000 --> 05:49.000 I will talk more about Python values, a little bit later, 05:49.000 --> 05:52.000 but this would be the ideal way to actually integrate 05:52.000 --> 05:55.000 into Python pipelines, 05:55.000 --> 05:58.000 that if you need to do some rendering. 05:58.000 --> 06:02.000 And a final scenario is you want to quickly visualize 06:02.000 --> 06:04.000 in the web. 06:04.000 --> 06:06.000 Well, you can actually do that, 06:06.000 --> 06:08.000 because FAD is indeed in C++, 06:08.000 --> 06:12.000 but we do compile it with web assembly, 06:12.000 --> 06:15.000 and so you can just use our web viewer, 06:15.000 --> 06:18.000 and it's on FAD.up, slash viewer. 06:18.000 --> 06:23.000 And if you have an actual 3D model on your phone, 06:23.000 --> 06:25.000 you would be able to connect to that. 06:25.000 --> 06:27.000 If you have a good GPU on your phone, 06:27.000 --> 06:29.000 or you can do that on your computer, of course. 06:29.000 --> 06:32.000 So here we have just an example of opening it's a bit dark, 06:32.000 --> 06:36.000 so you should have switched the background to lighter one, 06:36.000 --> 06:38.000 but you see the points. 06:38.000 --> 06:42.000 Okay, so is it just a viewer? 06:42.000 --> 06:45.000 Because I mean, being just a viewer is fine, 06:45.000 --> 06:48.000 you don't want your software to do this, 06:48.000 --> 06:50.000 and that, and make coffee, and then, 06:50.000 --> 06:53.000 I don't know, make your bed, and stuff like that, 06:53.000 --> 06:57.000 but FAD goes a bit further than that. 06:57.000 --> 07:01.000 So, okay, you open, you open the FAD window, 07:01.000 --> 07:04.000 and you have your data, it looks wet, 07:04.000 --> 07:06.000 but then what can you do? 07:06.000 --> 07:09.000 Well, you can twist H on your keyboard, 07:09.000 --> 07:12.000 and it will show this, what we call that the cheat cheat, 07:12.000 --> 07:15.000 that will show you all this interactive key bindings 07:15.000 --> 07:19.000 that will let you modify the way the data is displayed. 07:19.000 --> 07:22.000 There is actually many of them. 07:22.000 --> 07:25.000 At this point, with Mikael, we're starting to lose tracks 07:25.000 --> 07:28.000 as to how many different controls we have, 07:28.000 --> 07:30.000 because we have the more and more. 07:30.000 --> 07:33.000 And we will soon add a search bar on top of that, 07:33.000 --> 07:36.000 because it's starting to be complex to find what you're looking for, 07:36.000 --> 07:39.000 but yeah, there are a lot of bindings. 07:39.000 --> 07:41.000 And all these options that you do, 07:41.000 --> 07:43.000 basically, crazy things. 07:43.000 --> 07:47.000 Here, we have an example where we have volume of data on the left, 07:47.000 --> 07:49.000 and then using volume rendering, 07:49.000 --> 07:52.000 and some specific color mapping, 07:52.000 --> 07:56.000 we are able, in fact, to generate this kind of rendering. 07:56.000 --> 07:59.000 This is just a volume rendering of medical data, 07:59.000 --> 08:00.000 but this is something you can do. 08:00.000 --> 08:02.000 In fact, which is not something you would expect from us 08:02.000 --> 08:04.000 with if you were up to 10. 08:04.000 --> 08:05.000 And that's just an example. 08:05.000 --> 08:09.000 There is tons of common item shifts. 08:09.000 --> 08:12.000 And all these options that you can do from the common line, 08:12.000 --> 08:14.000 all you can do, interactively, 08:14.000 --> 08:17.000 you can also control from a configuration file. 08:17.000 --> 08:22.000 So that means that if you are always using the same options, 08:22.000 --> 08:23.000 always using the same interactions, 08:23.000 --> 08:27.000 you're able to just put that in your configuration file, 08:27.000 --> 08:29.000 and then the next time you open file, 08:29.000 --> 08:32.000 it will just look exactly the way you want it to look. 08:32.000 --> 08:36.000 And you can match it with different extensions 08:36.000 --> 08:38.000 or different, even, fine name. 08:38.000 --> 08:39.000 So that's your configuration block, 08:39.000 --> 08:41.000 or specific for each of your files. 08:41.000 --> 08:44.000 So this way, you know, oh, this is my GLTF files. 08:44.000 --> 08:45.000 I want to learn things like this, 08:45.000 --> 08:50.000 and my stepfile, I want to learn them differently. 08:50.000 --> 08:51.000 Okay. 08:51.000 --> 08:58.000 So that is also a very nice documentation 08:58.000 --> 09:00.000 that we actually write all of, 09:00.000 --> 09:03.000 we just tried to make it as good as we can. 09:03.000 --> 09:06.000 And this documentation is available on our website. 09:06.000 --> 09:08.000 It's also available as a dash-l, 09:08.000 --> 09:10.000 but it's much, much more complex, 09:10.000 --> 09:12.000 complete on the website. 09:12.000 --> 09:14.000 This is a searchable website, 09:14.000 --> 09:16.000 so it's very easy to find the information you're looking for. 09:16.000 --> 09:18.000 And we even have version, 09:18.000 --> 09:20.000 help, so you can look, 09:20.000 --> 09:22.000 if you're demanding the version you have, 09:22.000 --> 09:24.000 you can look on the website. 09:24.000 --> 09:26.000 So there is a QR code here, 09:26.000 --> 09:30.000 but it will be available at the end of the slide as well. 09:30.000 --> 09:31.000 Okay. 09:31.000 --> 09:35.000 So what kind of options can we use, 09:35.000 --> 09:38.000 and what does actually exist in terms of options, 09:38.000 --> 09:39.000 in fact? 09:39.000 --> 09:42.000 So here I've selected a few of the, 09:42.000 --> 09:44.000 I would say most interested option, 09:44.000 --> 09:45.000 but there is many other, 09:45.000 --> 09:46.000 I will not talk about it. 09:47.000 --> 09:48.000 If you want to do something, 09:48.000 --> 09:49.000 just ask, 09:49.000 --> 09:50.000 and I will let you know, 09:50.000 --> 09:52.000 is it possible or not? 09:52.000 --> 09:54.000 Okay, so animations. 09:54.000 --> 09:56.000 This is something that, 09:56.000 --> 09:58.000 of course, if you do CAD, 09:58.000 --> 09:59.000 that's not what you think, 09:59.000 --> 10:00.000 but if you do GLTF files, 10:00.000 --> 10:01.000 of course, 10:01.000 --> 10:03.000 that makes a lot of sense. 10:03.000 --> 10:04.000 So yeah, 10:04.000 --> 10:05.000 lighting is that great here, 10:05.000 --> 10:07.000 but at least this one looks great. 10:07.000 --> 10:10.000 So you can have multiple animation, 10:10.000 --> 10:11.000 in some format, 10:11.000 --> 10:13.000 you're able to select the animation you want to show. 10:13.000 --> 10:15.000 You can control the speed, 10:15.000 --> 10:17.000 you can go frame by frame. 10:17.000 --> 10:19.000 So which is very useful, 10:19.000 --> 10:23.000 when you have low resolution animation, 10:23.000 --> 10:25.000 like we do CAD, 10:25.000 --> 10:27.000 on the top right, 10:27.000 --> 10:28.000 which is a, 10:28.000 --> 10:30.000 it's a doom model, 10:30.000 --> 10:32.000 which is like just a few frame of animation, 10:32.000 --> 10:34.000 and you can go frame by frame. 10:36.000 --> 10:38.000 Okay, textures. 10:38.000 --> 10:42.000 So when you load GLTF file, 10:42.000 --> 10:43.000 which is okay here, 10:43.000 --> 10:45.000 it will load the texture as well, 10:45.000 --> 10:46.000 if they're available. 10:46.000 --> 10:47.000 Sometimes they're baked in the file, 10:47.000 --> 10:49.000 sometimes they're a PNG files, 10:49.000 --> 10:50.000 which are on the side, 10:50.000 --> 10:52.000 but it will work automatically. 10:52.000 --> 10:54.000 But if you want to force a specific texture, 10:54.000 --> 10:57.000 because you're working on the texture on a PNG file, 10:57.000 --> 10:58.000 on the side, 10:58.000 --> 11:00.000 you can just side load it with a common line option. 11:00.000 --> 11:02.000 So you just modify it at the first, 11:02.000 --> 11:03.000 I'm not going on it, 11:03.000 --> 11:04.000 and just, that's it. 11:07.000 --> 11:08.000 With support, FDRI. 11:08.000 --> 11:12.000 So FDRI is a way to add some kind of a, 11:12.000 --> 11:16.000 360 degree is background on everywhere on, 11:16.000 --> 11:17.000 in your scene. 11:17.000 --> 11:19.000 So this HGRI, 11:19.000 --> 11:21.000 we let you not only add a background, 11:21.000 --> 11:23.000 if you want to show it, 11:23.000 --> 11:24.000 but also to light, 11:24.000 --> 11:26.000 your model using this HGRI. 11:26.000 --> 11:27.000 This lighting, 11:27.000 --> 11:30.000 we give very, very, very much nice, 11:30.000 --> 11:31.000 more underings. 11:31.000 --> 11:33.000 It looks very realistic. 11:33.000 --> 11:34.000 I mean, 11:34.000 --> 11:35.000 it's not very tracing, of course, 11:35.000 --> 11:38.000 but it looks much better with an HGRI, 11:38.000 --> 11:40.000 that without an HGRI in terms of lighting. 11:40.000 --> 11:43.000 And you can even blur the HGRI, 11:43.000 --> 11:45.000 so that it looks a bit nicer. 11:45.000 --> 11:49.000 And if you don't know where to find HGRI, 11:49.000 --> 11:51.000 to do this kind of nicer rendering, 11:51.000 --> 11:52.000 you can download it on the web, 11:52.000 --> 11:54.000 there is a website called PolyEvan, 11:54.000 --> 11:58.000 which provides HGRI on the CC zero license. 11:58.000 --> 12:00.000 So this is very useful. 12:03.000 --> 12:06.000 Okay, so you can also do multiple files. 12:06.000 --> 12:08.000 So as of now, 12:08.000 --> 12:10.000 I'll only show you how to print a single file, 12:10.000 --> 12:12.000 but if you have multiple files that are, 12:12.000 --> 12:14.000 for example, part of a bigger, 12:14.000 --> 12:16.000 a bigger model, 12:16.000 --> 12:18.000 forcefully printing, for example, 12:18.000 --> 12:20.000 where you can just open them all together 12:20.000 --> 12:21.000 into a single view, 12:21.000 --> 12:23.000 and this is exactly what I did here. 12:23.000 --> 12:25.000 So here we have, 12:25.000 --> 12:26.000 I don't know, 12:26.000 --> 12:28.000 maybe 15 models, 12:28.000 --> 12:29.000 that actually, 12:29.000 --> 12:31.000 if you open it with a multi-final mode, 12:31.000 --> 12:33.000 it will just show up as this single model. 12:33.000 --> 12:35.000 But it's actually multiple models being loaded. 12:36.000 --> 12:39.000 And we actually have multiple multi-final models 12:39.000 --> 12:41.000 that you can actually use a regax 12:41.000 --> 12:44.000 to choose how you want to go by and stuff like that. 12:46.000 --> 12:48.000 In terms of advanced rendering, 12:48.000 --> 12:49.000 we of course suppose, 12:49.000 --> 12:50.000 support blending, 12:50.000 --> 12:52.000 if you have opacity on your files. 12:52.000 --> 12:54.000 So here on the left, 12:54.000 --> 12:55.000 without blending, 12:55.000 --> 12:56.000 toned down, 12:56.000 --> 12:59.000 you of course it's all mapped up and everything. 12:59.000 --> 13:00.000 And on the right, 13:00.000 --> 13:02.000 we have the blending correctly set up, 13:02.000 --> 13:04.000 so that you can actually see through, 13:05.000 --> 13:07.000 because there is some opacity on the parts, 13:07.000 --> 13:09.000 but it looks correct. 13:09.000 --> 13:11.000 As I've actually different blending modes, 13:11.000 --> 13:13.000 I will not go into specifics, 13:13.000 --> 13:14.000 but if you have questions, 13:14.000 --> 13:16.000 make it would be available to answer that. 13:16.000 --> 13:18.000 We have so support ambient occlusion, 13:18.000 --> 13:23.000 which is a way to have fake shadow on your models, 13:23.000 --> 13:27.000 and that's look very great for this kind of model. 13:27.000 --> 13:29.000 Here we have some intricate geometries, 13:29.000 --> 13:32.000 you actually can understand much more outwards. 13:35.000 --> 13:39.000 Okay, so this one is a video. 13:39.000 --> 13:43.000 We also support Gaussian splitting, that for you. 13:43.000 --> 13:47.000 You can actually open your Gaussian splitting files. 13:47.000 --> 13:49.000 So there is PLY, 13:49.000 --> 13:51.000 the splat, the SPZ, 13:51.000 --> 13:52.000 that you can open, 13:52.000 --> 13:54.000 and it will just show up like this. 13:54.000 --> 13:56.000 So if you don't know what Gaussian splitting is, 13:56.000 --> 13:59.000 I will just explain in less than a minute. 13:59.000 --> 14:03.000 It's basically lots of points with some kind of shapes and colors, 14:04.000 --> 14:06.000 but it's an interactive photo, 14:06.000 --> 14:07.000 where you can move around, 14:07.000 --> 14:11.000 unless you stay kind of at the same location, 14:11.000 --> 14:14.000 where the acquisition of the data 14:14.000 --> 14:17.000 was made by some kind of a specific camera. 14:17.000 --> 14:20.000 And yeah, this is not really supported in fact, 14:20.000 --> 14:25.000 and there is actually not that many viewer that supports that. 14:25.000 --> 14:28.000 It's a specific thing. 14:29.000 --> 14:33.000 You can also do some analysis. 14:33.000 --> 14:36.000 If you want to know how many nodes, 14:36.000 --> 14:37.000 how many cells, 14:37.000 --> 14:39.000 the bounds of the scene, 14:39.000 --> 14:42.000 you can use just very simple tool to do that. 14:42.000 --> 14:43.000 So here we have, 14:43.000 --> 14:46.000 you can show in the scene the number of points. 14:46.000 --> 14:47.000 And in the terminal, 14:47.000 --> 14:49.000 you can have many more information, 14:49.000 --> 14:50.000 for example, 14:50.000 --> 14:52.000 the name of the animations and stuff like that. 14:52.000 --> 14:56.000 So you can use it as an analysis tool. 14:56.000 --> 15:00.000 And you can even, from the command line, 15:00.000 --> 15:02.000 say you don't want to do an actual render, 15:02.000 --> 15:04.000 you just want to, 15:04.000 --> 15:05.000 you just want to, 15:05.000 --> 15:07.000 when it without rendering and just, 15:07.000 --> 15:09.000 oh, give me some info about my file, 15:09.000 --> 15:10.000 basically, 15:10.000 --> 15:14.000 you can definitely do that in that very useful. 15:14.000 --> 15:17.000 And we also have scientific visualization, 15:17.000 --> 15:19.000 which is kind of a specific thing for us, 15:19.000 --> 15:20.000 with the viewer, 15:20.000 --> 15:23.000 but it's explained by the history of the project, 15:23.000 --> 15:25.000 because we basically started with that. 15:25.000 --> 15:28.000 That was the first features we had in the project, 15:28.000 --> 15:29.000 like, 15:29.000 --> 15:32.000 because we come from a background of scientific visualization, 15:32.000 --> 15:33.000 mechanics, 15:33.000 --> 15:34.000 so that's why. 15:34.000 --> 15:35.000 So yeah, 15:35.000 --> 15:37.000 you able to, 15:37.000 --> 15:40.000 shows a column up on the surface of the model. 15:40.000 --> 15:42.000 If there is a data on the surface of the model, 15:42.000 --> 15:43.000 to show column up with, 15:43.000 --> 15:45.000 and you can also do volume rendering, 15:45.000 --> 15:47.000 here's the same idea as before, 15:47.000 --> 15:50.000 where you able to do volume render with, 15:50.000 --> 15:52.000 with a different colors and to blending with the, 15:52.000 --> 15:53.000 with the depth. 15:56.000 --> 15:57.000 Well, is that it? 15:57.000 --> 15:58.000 I mean, 15:58.000 --> 15:59.000 that's a lot of features. 15:59.000 --> 16:01.000 You can use this very simply, 16:01.000 --> 16:03.000 and there is a ton of features that are available, 16:03.000 --> 16:04.000 if you want them, 16:04.000 --> 16:05.000 we do not, 16:05.000 --> 16:06.000 we do not force them to you, 16:06.000 --> 16:07.000 it's just the here, 16:07.000 --> 16:08.000 you use them, 16:08.000 --> 16:11.000 but there is actually much more. 16:11.000 --> 16:12.000 First, 16:12.000 --> 16:15.000 Fed is plugin based. 16:15.000 --> 16:17.000 That means that all of our dependencies, 16:17.000 --> 16:18.000 except VtK, 16:18.000 --> 16:20.000 which is a main dependencies that you need, 16:20.000 --> 16:22.000 all of our dependencies are optional. 16:22.000 --> 16:24.000 So, if you build, 16:24.000 --> 16:25.000 you yourself, 16:25.000 --> 16:28.000 you don't need to actually enable all of these dependencies, 16:28.000 --> 16:29.000 if you don't want them, 16:29.000 --> 16:30.000 if you don't need them, 16:30.000 --> 16:33.000 so you will end up with less complexity, 16:33.000 --> 16:34.000 of course, 16:34.000 --> 16:35.000 because you don't need to build, 16:35.000 --> 16:37.000 let's say you don't want CID, 16:37.000 --> 16:39.000 you don't do steps, you don't do HHS, 16:39.000 --> 16:40.000 and you don't need open cascades, 16:40.000 --> 16:42.000 then you don't need to enable open cascades, 16:42.000 --> 16:44.000 and then you have a simpler build system. 16:44.000 --> 16:45.000 So, 16:45.000 --> 16:49.000 we have that for all of all our dependencies, 16:49.000 --> 16:51.000 you can turn them off if you don't want them. 16:51.000 --> 16:52.000 And, 16:52.000 --> 16:55.000 you can also use this plugin mechanism to create your own plugin. 16:55.000 --> 16:58.000 If you have your own file formats, 16:58.000 --> 17:00.000 that you want to create a plugin for, 17:00.000 --> 17:03.000 and you want to be able to load your own file into Fed, 17:03.000 --> 17:04.000 to do some renderings, 17:04.000 --> 17:06.000 you can easily do that, 17:06.000 --> 17:07.000 and someone already did. 17:07.000 --> 17:11.000 We have Abacus plugin for Fed. 17:11.000 --> 17:14.000 Abacus is a proprietary library, 17:14.000 --> 17:18.000 that's for to open this kind of file, 17:18.000 --> 17:19.000 which are Abacus files. 17:20.000 --> 17:23.000 Of course, we cannot ship it with our bandwidth, 17:23.000 --> 17:24.000 because it's proprietary, 17:24.000 --> 17:26.000 but someone did that, 17:26.000 --> 17:29.000 and they are able to view their Abacus files. 17:32.000 --> 17:33.000 Okay, 17:33.000 --> 17:35.000 and another thing that you can do, 17:35.000 --> 17:37.000 is that you need to understand, 17:37.000 --> 17:39.000 is that Fed is not only an application, 17:39.000 --> 17:41.000 but it's a library. 17:41.000 --> 17:43.000 There is actually Fed's application, 17:43.000 --> 17:44.000 and the live Fed, 17:44.000 --> 17:47.000 which is a library that is inside of Fed. 17:47.000 --> 17:50.000 And this library is actually shipped in our binaries, 17:50.000 --> 17:51.000 or if you build yourself, 17:51.000 --> 17:54.000 or of course, Abacus 2s a library. 17:54.000 --> 17:57.000 So it's simply 17. 17:57.000 --> 17:58.000 And here, 17:58.000 --> 17:59.000 the example here, 17:59.000 --> 18:00.000 or not for you to actually read, 18:00.000 --> 18:01.000 I don't understand, 18:01.000 --> 18:02.000 it's just to show you, 18:02.000 --> 18:04.000 this is the number of line of code you need, 18:04.000 --> 18:06.000 if you want to show a window of Fed, 18:06.000 --> 18:07.000 with a model inside of it. 18:07.000 --> 18:12.000 That's actually six lines of codes. 18:12.000 --> 18:13.000 And another, 18:13.000 --> 18:15.000 another one is another example, 18:15.000 --> 18:16.000 that's a different kind of example, 18:16.000 --> 18:17.000 where you don't, 18:17.000 --> 18:19.000 you have interactivity or not. 18:19.000 --> 18:20.000 So yeah, 18:20.000 --> 18:21.000 that's, 18:21.000 --> 18:22.000 where it is, 18:22.000 --> 18:23.000 there is not much more to it. 18:23.000 --> 18:26.000 And it is also available in Python. 18:26.000 --> 18:27.000 So here, 18:27.000 --> 18:29.000 I have an example in Python, 18:29.000 --> 18:31.000 to do some kind of interactivity, 18:31.000 --> 18:32.000 wondering, 18:32.000 --> 18:33.000 with Python buildings, 18:33.000 --> 18:35.000 and it's available on Pipi, 18:35.000 --> 18:36.000 you can put in Stalfet, 18:36.000 --> 18:37.000 and you just get the Python buildings, 18:37.000 --> 18:39.000 and you can start import Fed, 18:39.000 --> 18:40.000 and that's it. 18:40.000 --> 18:42.000 It is not super clear, 18:42.000 --> 18:44.000 so if it was a contrast, 18:44.000 --> 18:47.000 but it's basically someone writes, 18:47.000 --> 18:49.000 Python script using Fed, 18:49.000 --> 18:51.000 and then they wonder, 18:51.000 --> 18:52.000 in two of the time you're using Python. 18:52.000 --> 18:54.000 So that's a specific use case, 18:54.000 --> 18:59.000 but that's funny that it's actually possible to do that. 18:59.000 --> 19:01.000 And here are some showcase of things 19:01.000 --> 19:04.000 that have been done using the Python buildings. 19:04.000 --> 19:07.000 So you can have nice camera movements, 19:07.000 --> 19:10.000 because you can control the camera, 19:10.000 --> 19:12.000 using the bindings, 19:12.000 --> 19:14.000 so you can just move it around, 19:14.000 --> 19:17.000 using your own camera pass. 19:17.000 --> 19:20.000 Here we have an option that I'd not talk about, 19:20.000 --> 19:22.000 which is called Final Shader, 19:22.000 --> 19:26.000 that lets you run an OpenGL Shader at the end of the rendering, 19:26.000 --> 19:28.000 to do this kind of stuff. 19:28.000 --> 19:29.000 And here, 19:29.000 --> 19:31.000 the compositing is not done, 19:31.000 --> 19:32.000 with Fed, 19:32.000 --> 19:33.000 the compositing of different images, 19:33.000 --> 19:35.000 but we did generate all the pages, 19:35.000 --> 19:39.000 and these are compositing using another tool. 19:40.000 --> 19:42.000 So all things you can do, 19:42.000 --> 19:45.000 which are actually quite easy to do with Fed. 19:45.000 --> 19:48.000 But I talk about Python buildings, 19:48.000 --> 19:49.000 but that's not it. 19:49.000 --> 19:51.000 We actually have C buildings, 19:51.000 --> 19:52.000 Java bindings, 19:52.000 --> 19:55.000 and of course, Java script binding using WebAssembly, 19:55.000 --> 19:59.000 in order to be able to do the web version. 19:59.000 --> 20:04.000 And the C binding have been truly important, 20:04.000 --> 20:07.000 because we have already seen people creating Julia bindings, 20:07.000 --> 20:10.000 and we have someone else working on Web bindings, 20:10.000 --> 20:14.000 and this will not be impossible without the C bindings, of course. 20:14.000 --> 20:17.000 So if you want to give it a go, 20:17.000 --> 20:19.000 I'm sure you will find a way to use Fed 20:19.000 --> 20:22.000 even if you use some kind of special language. 20:22.000 --> 20:24.000 We'll find a solution. 20:24.000 --> 20:28.000 Fed can be integrated into existing applications. 20:28.000 --> 20:30.000 We have examples for that, 20:30.000 --> 20:32.000 integration into QML, 20:32.000 --> 20:34.000 integration into QUT, into FLCK, 20:35.000 --> 20:38.000 this is just an example we managed to put together, 20:38.000 --> 20:41.000 but I'm sure any framework in any framework 20:41.000 --> 20:43.000 you will be able to use or API 20:43.000 --> 20:46.000 to integrate into your own application. 20:46.000 --> 20:49.000 And this way you would just be able to integrate a window 20:49.000 --> 20:51.000 to show a 3D model into your application, 20:51.000 --> 20:54.000 without the need to write any kind of 3D model 20:54.000 --> 20:56.000 reading or wondering. 20:58.000 --> 21:01.000 There is an example of that called Exhibit. 21:01.000 --> 21:04.000 It's actually pretty well known application at this point, 21:04.000 --> 21:07.000 because it's part of the GNOME ecosystem, 21:07.000 --> 21:10.000 and there will just be people using Exhibit without knowing 21:10.000 --> 21:13.000 that there is a backend to it, which is called the default. 21:13.000 --> 21:16.000 But that's what is made for, right? 21:16.000 --> 21:20.000 Okay, and in terms of perspective, 21:20.000 --> 21:23.000 what are we cooking right now? 21:23.000 --> 21:27.000 So there is a big plan to do Android app. 21:27.000 --> 21:30.000 So here we have the example of the Android app on the right. 21:30.000 --> 21:33.000 It's kind of working, 21:33.000 --> 21:36.000 but we still have a prototype working, 21:36.000 --> 21:38.000 but we did not realize the amount of work 21:38.000 --> 21:41.000 to do something that is clean and quick and cheap. 21:41.000 --> 21:43.000 So it will come in 2026, 21:43.000 --> 21:46.000 but we have no dates in mine yet. 21:46.000 --> 21:49.000 And there is also IFC support. 21:49.000 --> 21:52.000 So I'm not sure if you do IFC files, 21:52.000 --> 21:55.000 but this is something that is happening 21:55.000 --> 21:57.000 in three months. 21:57.000 --> 22:00.000 The next question we get IFC support. 22:00.000 --> 22:04.000 So this has been requested by the community for a long time, 22:04.000 --> 22:07.000 and we are very happy to be able to ship it very soon. 22:07.000 --> 22:10.000 Yes, that's it for me. 22:10.000 --> 22:13.000 Very happy to take any questions. 22:13.000 --> 22:17.000 Yes? 22:17.000 --> 22:19.000 Cool. 22:27.000 --> 22:30.000 This is amazing, and I have so many questions. 22:30.000 --> 22:32.000 I'm going to chase you down. 22:32.000 --> 22:34.000 I've got a lot to talk about, 22:34.000 --> 22:38.000 but a couple specifically. 22:38.000 --> 22:42.000 So I want to do everything to serve aside. 22:42.000 --> 22:47.000 So I want to do rendering three models for preview, 22:47.000 --> 22:50.000 which is on the headless serve. 22:50.000 --> 22:51.000 Okay. 22:51.000 --> 22:53.000 If the time when dealing with graphics, 22:53.000 --> 22:55.000 you need like a display context. 22:55.000 --> 22:57.000 Can it be done? 22:57.000 --> 22:58.000 Absolutely. 22:58.000 --> 22:59.000 Amazing. 22:59.000 --> 23:02.000 You can use IGL or OSMESA to do some rendering. 23:02.000 --> 23:05.000 OSMESA is out of luck now, 23:05.000 --> 23:08.000 that IGL using CPU is coming up, 23:08.000 --> 23:10.000 so anywhere you can use, 23:11.000 --> 23:14.000 and it's also dynamically loaded, 23:14.000 --> 23:17.000 so you don't need different executable or stuff like that, 23:17.000 --> 23:19.000 because we don't link with the intel. 23:19.000 --> 23:21.000 So you can just, you can actually, 23:21.000 --> 23:24.000 there is an option called dash dash for rendering back end. 23:24.000 --> 23:26.000 When you say, you can only use, 23:26.000 --> 23:27.000 and if you don't say it, 23:27.000 --> 23:29.000 it will be automatically tried to find the right one. 23:29.000 --> 23:30.000 So, yes? 23:30.000 --> 23:31.000 Brilliant. 23:31.000 --> 23:34.000 Also, is anybody working on Ruby behind things? 23:34.000 --> 23:35.000 If not, I might. 23:40.000 --> 23:52.000 So, thank you for this works. 23:52.000 --> 23:57.000 So, if I were to write plugin for something super, 23:57.000 --> 24:01.000 super niche, would you want to have it? 24:01.000 --> 24:07.000 If the specification of the format of public, 24:08.000 --> 24:09.000 yes. 24:09.000 --> 24:11.000 If this is your own internal format, 24:11.000 --> 24:13.000 that nobody can write file for. 24:13.000 --> 24:14.000 No. 24:14.000 --> 24:17.000 But, we will advertise that this plugin exists, 24:17.000 --> 24:20.000 and patch your link to your GitHub, 24:20.000 --> 24:22.000 or to your repo, anywhere but. 24:22.000 --> 24:23.000 Okay, that's great. 24:23.000 --> 24:25.000 We have reverse engineering, 24:25.000 --> 24:26.000 an old game, 24:26.000 --> 24:29.000 and it has its own model format. 24:29.000 --> 24:31.000 Oh, which game is it? 24:31.000 --> 24:35.000 It's like there was this old touch publisher, 24:35.000 --> 24:36.000 called Derby Lex. 24:36.000 --> 24:37.000 No, I'm not made. 24:37.000 --> 24:39.000 They made like racing games. 24:39.000 --> 24:40.000 Okay, okay. 24:40.000 --> 24:43.000 I'm trying to figure out how I make the models 24:43.000 --> 24:44.000 more visible to me, 24:44.000 --> 24:45.000 and this would be great. 24:45.000 --> 24:46.000 Yeah. 24:46.000 --> 24:47.000 So, with reverse engineering, 24:47.000 --> 24:49.000 that is always a legality problem. 24:49.000 --> 24:51.000 So, if that's clear that the code is legal, 24:51.000 --> 24:53.000 yeah, no problem to integrate it. 24:53.000 --> 24:56.000 But, yeah, that's just the one thing that on top of my mind. 24:56.000 --> 24:57.000 But, if it works, 24:57.000 --> 25:00.000 if you have put the specs that you will be basing 25:00.000 --> 25:01.000 a little bit somewhere, 25:01.000 --> 25:03.000 so that the people in your community can use, 25:03.000 --> 25:04.000 of course, as you can see, 25:04.000 --> 25:06.000 we support QuakeMDL, 25:06.000 --> 25:08.000 which is Canada-Nish. 25:08.000 --> 25:10.000 I would say, I mean, the people from the Quake community 25:10.000 --> 25:11.000 are super happy to get it, 25:11.000 --> 25:12.000 but nobody else care about it, 25:12.000 --> 25:14.000 but we are very happy to have made it. 25:14.000 --> 25:16.000 Because of spec or like everywhere, 25:16.000 --> 25:18.000 you can find them on different websites. 25:18.000 --> 25:19.000 So, that was actually, 25:19.000 --> 25:21.000 is that made sense for us to add it. 25:21.000 --> 25:23.000 Okay, thank you. 25:27.000 --> 25:28.000 Short question. 25:28.000 --> 25:30.000 Is the next presenter here? 25:34.000 --> 25:35.000 Okay. 25:35.000 --> 25:37.000 It's supposed to be graphite, I guess. 25:37.000 --> 25:40.000 Okay, I can have more questions. 25:49.000 --> 25:52.000 Do you do anything about export of models? 25:52.000 --> 25:53.000 No. 25:53.000 --> 25:55.000 This is something we consider adding. 25:55.000 --> 25:57.000 The problem is that, 25:57.000 --> 26:00.000 whiting an exporter is another story 26:00.000 --> 26:01.000 and a reader. 26:01.000 --> 26:03.000 So, maybe at some point, 26:03.000 --> 26:06.000 someone we could improve the leapfade 26:06.000 --> 26:08.000 to be able to have some kind of export back in, 26:08.000 --> 26:10.000 and then write another project 26:10.000 --> 26:12.000 that would be using the leapfade to do the 26:12.000 --> 26:14.000 importance and the export. 26:14.000 --> 26:16.000 Yeah, it's a lot of work, 26:16.000 --> 26:19.000 and not really in the planning. 26:21.000 --> 26:23.000 Can I jump in with my own question? 26:23.000 --> 26:25.000 So, as a beginner, 26:25.000 --> 26:28.000 this, I mean, it looks like a very interesting project. 26:28.000 --> 26:30.000 You mentioned there was, you know, 26:30.000 --> 26:33.000 you can do it simply through Pip and I Python. 26:33.000 --> 26:34.000 Yeah. 26:34.000 --> 26:36.000 So, is there good documentation, 26:36.000 --> 26:39.000 any sort of tutorials online on how to get started 26:39.000 --> 26:41.000 with creating your own? 26:41.000 --> 26:42.000 Yeah. 26:42.000 --> 26:46.000 So, we do have a page dedicated to how to use 26:46.000 --> 26:48.000 the leapfade in Python. 26:48.000 --> 26:50.000 To be honest, it could be expanded, 26:50.000 --> 26:53.000 but we do have, in our website, 26:53.000 --> 26:54.000 an example to show that, 26:54.000 --> 26:56.000 and then inside the repo, 26:56.000 --> 26:58.000 you have an example, directory, 26:58.000 --> 27:01.000 that contains five or six different examples 27:01.000 --> 27:04.000 on how to do what you want with Python. 27:04.000 --> 27:07.000 And we are also dedicated with a little bit, 27:07.000 --> 27:10.000 called FedPitonX2az, 27:10.000 --> 27:13.000 that is maintained by someone in our community. 27:13.000 --> 27:16.000 And in this Python module, 27:16.000 --> 27:19.000 they use that actually created small scripts, 27:19.000 --> 27:21.000 and small utilities that let you do, 27:21.000 --> 27:23.000 you know, the movement of camera, 27:23.000 --> 27:25.000 stuff like that, it's actually baked. 27:25.000 --> 27:26.000 Yeah. 27:26.000 --> 27:27.000 Cool. 27:27.000 --> 27:28.000 Thank you. 27:28.000 --> 27:29.000 Oh, we've got a question at the back. 27:29.000 --> 27:31.000 Also, do we, I think we've got our next speaker. 27:31.000 --> 27:32.000 Sure. 27:32.000 --> 27:33.000 We're all about it. 27:33.000 --> 27:34.000 One last question. 27:34.000 --> 27:35.000 One last question. 27:35.000 --> 27:36.000 One last question. 27:42.000 --> 27:44.000 That's the very best one, though. 27:44.000 --> 27:45.000 Yes. 27:45.000 --> 27:46.000 Thank you. 27:46.000 --> 27:48.000 Just wondering about how dynamic it is. 27:48.000 --> 27:50.000 Like, you showed it at the end 27:50.000 --> 27:52.000 that you can animate the camera. 27:52.000 --> 27:53.000 Yeah. 27:53.000 --> 27:56.000 Can you actually animate the 3D model, no other thing? 27:56.000 --> 27:57.000 Yeah, absolutely. 27:57.000 --> 28:00.000 Maybe there was a clear, but I had a slide on animation. 28:00.000 --> 28:02.000 You can definitely do your animation. 28:02.000 --> 28:05.000 Some formats are more optimized and also. 28:05.000 --> 28:07.000 For example, we do have a screening and morphing 28:07.000 --> 28:09.000 baked in the GPU. 28:09.000 --> 28:11.000 In GPU rendering for certain formats, 28:11.000 --> 28:12.000 but not for other. 28:12.000 --> 28:14.000 So that really depends on the format you're using. 28:14.000 --> 28:17.000 We try to make it as good as possible for animation, 28:17.000 --> 28:20.000 but set in formats, let us do nice things for GPU 28:20.000 --> 28:21.000 rendering. 28:21.000 --> 28:23.000 Also require to just move on the machines, 28:23.000 --> 28:24.000 stuff like that. 28:24.000 --> 28:27.000 And you can do it from the API directly. 28:27.000 --> 28:28.000 Yeah. 28:28.000 --> 28:29.000 Yeah. 28:29.000 --> 28:30.000 Thank you. 28:36.000 --> 28:38.000 If you want stickers, we have stickers here. 28:38.000 --> 28:40.000 So grab your sticker.
