you will need Vitamin library to compile and run the project.
get it from: http://www.pixelnerve.com/processing/libraries/vitamin

have fun.

your updated version is even better, i really need to take a deeper look at the code. There is a lot to learn

V,

I've been looking through the code and a good portion of the awesome comes from the subsurface.cgfx effect.  Did you write this yourself?  I am new to all of this and some poking around on the internet (and the fact that I had to install the nvidia Cg toolkit to run th eprogeam) led me to this: http://http.developer.nvidia.com/CgTutorial/cg_tutorial_chapter01.html  Did you write the subsurface.cgfx using this language?  Is there a better way to get sweet glossy effects or should I keep on researching/learning about the programming language Cg?  Thanks a whoooole bunch.  I am learning so much from this thread.

Update:  Whoa, I just realized the cgfx file is not a compiled file, but it actually contains CgFX code and a link to a discussion about the effect.  Awesome!

This is some great code! I'm having a little trouble figuring out how a line arc might be designated to end at a specific x,y,z coordinate though. Right now, I'm translating the arc's initial position within the draw function to start it at a specific point.  In order to specify where a specific arc's ending coordinates would be,  is there a specific calculation that I would have to make to convert the x,y,z so that it would arc in that specific direction/length?
