IMAGE DESCRIPTION: 


          When I was a little boy... mmmh... sorry,
        when I was young ( I'm still little :o) ), 
        I've always imagined the sorcerers with
        cauldron. They cooked ...mmmm tasty...
        potions ( very tasty ), potions. This is
        one doesn't do anything, but it's so close
        from the one I've in my head since I've read
        my first tale... I put a straw in the potion
        because it's easier to drink something with
        a so bad taste through a straw. Good luck
        and don't spew up or it'll have no effect ! 




DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 


        Let's describe the different objects that
        composed this scene :

        o The cauldron : Classical CSG object. The 
          recipe have been drawn with Gimp ( Great
          software ! ) from gnu. The liquid in the
          cauldron is really bumped ( it's not only a
          texture ). I done this with the isosurface
          patch for povray ( Thanx to R.Suzuki ).
        o The straw : Two tubes and an articulation.
          The articulation have been made with
          an external C function ( Yeepee for
          this great patch) that return a
          bended cylinder with variable rays. 
          Something that look like this draw :
              _.,
         _.,-' /
         \    {    Is it clear for everyone ?
          }   \
         /_____\

        o The snake is the union of several C 
          functions ( always the same patch ! :o) )
          Its body have been made with a special one
          and the head with the intersection of an
          heart function and a scaled sphere...
        o The candles are from the include file
          written by Chris Young AKA Dastardly (thanx
          to him)
        o The eyes are... simple textured spheres ( yep
          true, no isofunctions ! ). Thanx to Yann Coupin
          for his help... 
        o To adjust the smoke have took a lot of time.
          I've change so many times the values of the
          rotate, turbulences, ... that I can't remember
          the initial values I've choose. Xemacs is
          a great modeler, but it lack a bit of visual :o)
