Non-photorealistic Volume Rendering
Technical illustrations Then, why not applying a
similar idea to volume rendering !!!
Why ? Better communication by abstraction
Enhancing the quality of visualization

How ?
Photorealistic volume rendering
NPR techniques
(original) volume data gradient vectors
(directions and magnitudes) distance
Multi-texturing hardware-accelerated
transfer functions color opacity
tone-shading silhouettes and highlights
color depth cueing
?Interactivity
Tuning parameters paletted textures
