notes from the bigfug

I?ve been getting into writing CGFX geometry shaders!  The following couple of pictures are generated inside PatchBox by passing in a simple flat grid of triangles.  The geometry shader turns them into cubes and calculates the shadow volumes on the fly.  Perhaps not the fastest solution, though my (getting long in the tooth) 8800 can still animate 900 cubes at 60fps.

These development pictures are rather lovely in themselves, and may end up being an installation, though I have further, much more complicated, plans for all this.
