Vascular Visualization
Non-parametric detection and visualization of vessels
Exaggerated shading for volumetric data
Improved shading for accentuating surface detail in volumetric data.
Advanced Illumination on the GPU
Ashikhmin lighting model, Banks lighting model and Gooch’s NPR lighting model
Nonphotorealistic Rendering of Volumes
Implemented the Volume Illustration techniques.
