Mipmapped Volume Rendering

Current Project Status

• meshing does not work correctly. check distance function and coordinate system
• thin volume rendering: pressing texture
• awful image quality..

TODO

• check meshing error in the cave
• alpha blending
• image quality problem - preintegration?
• scaling
• 16 bit support
• directory selection
• performance check

Multi volume support

• For now, it can load multiple volumes but the algorithm used here is very simple: overlaying two rendered images.
• Chih's work hasn't been integrated. I also have an idea about the correct multi volume rendering equation.

Downsampler

• Downsampler has lots of problems and I'd like to completely rewrite the program.
• OpenGL API will accelerate this process.
• Thin volume support

Renderer

• Removing padding

Transfer Function

• 1D transfer function

Optimization

• 3D Texture compression?
• Progressive refinement

Test Set

• Collect a set of volume so I can always check after major modification of the code

Software Release

• find an easy workflow minimizing editing
• script
• qmake

Tiled Display

• works with CGLX but without any optimization
• StarCAVE
• Varrier

Long Term Goal

• integrate with deskvox
• integrate with my multi-dimensional transfer function
