About two years ago, I decided to learn
NVIDIA's GPU programming environment, CUDA. I wrote a volume
renderer in it which can render anything you want as long as it is a
sphere.
The problem of course with volume
rendering is getting data to render. Volume datasets are usually
associated with scientific visualization and when you can get them at
all they are not trivial to process. They are real data about real
things and it requires serious work to make something of them.
So, for my tests I used normal 3D
objects but made every vertex a sphere. It turned out pretty well.
Here are two test images, one with glowy spheres and one with spheres
that were more hardedged.
You get extra credit if you can figure
out what they were originally.
Give up? The one on the bottom is an upside down SR-71. The one on top is something with a backbone, you can see the vertebrae clearly. Dont remember what it was, though.
