Abstract
Non-photorealistic rendering can be used to illustrate subtle spatial
relationships that might not be visible with more realistic rendering
techniques. We present a parallel hardware-accelerated rendering
technique, making extensive use of multi-texturing and paletted
textures, for the interactive non-photorealistic visualization of
scalar volume data. With this technique, we can render a
512x512x512 volume using non-photorealistic
techniques that include tone-shading, silhouettes, gradient-based
enhancement, and color depth cueing at multiple frames second.
The interactivity we achieve with our method allows
for the exploration of a large visualization parameter space
for the creation of effective illustrations.
