Geometry Compression
Coordinate representation
- do we really need 32-bit FP?
- 12.4 fixed point sufficient
- relative addressing (base address + deltas)
Color representation
- do we really need 32-bit RGBA if destination is 16-bit?
- relative color representations
Global compression
- entropy coding (0’s and 255’s are awfully common)
- reference coding (like simplified LZW)
Issues
- static vs. dynamic compression (changing data)
- lossless vs. lossy
