IMAGE DESCRIPTION: 

                              Hat and Cards

A scene of a stage magician's tools in action.  As a spotlight beems down,
a wand waves over the hat, while the cards come flying out into the audience.


DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 


I used sPatch to model the hat, cards, curtain and table.  This was my first
time 
using sPatch, so I was very pleased at how much power it gave me to create 
spline patches.  The hat was a l-shaped spine which I rotated.  The table top
was a similar rotation.  The table legs (not visible in scene :-( ) were
extruded.

I imported all those objects into PoVSB where I arranged, added lighting (used 
a spotlight to help the "stage look"), and a floor, a green cloth, and a wand in

PoVSB as well. 

I used a scanner to make the card image maps.

Almost all textures were made in Texture Magic.  I spent a long time getting
the
cards aligned just right.  The card image-maps were hand edited a bit as well.
My image maps were more square than my cards, thus the back had to be 
trimmed.  Really, my card image maps are funny.  I used only half the image
on the forground (card faces), the image maps have "backs", but they are not 
visible.  Also, because of an alignment problem that I didn't feel was worth
fixing
the backs of the cards are the same as the fronts.  The same is true of the 
background cards (card backs), they are actually double-backs.

I spent some time getting the math of the card rotation and movement right, and
still it isn't quite right.  I suspect the card faces don't really make sense on
close
scrutiny.  ...I'm not even sure anymore.

Special thanks to the people of "Work Week" at the Blue Forest Farm.
