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, as shown in the images on the color plate,
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.
