Fast Footprint MIPmapping Definition of the weighting table (1)
Idea:Snap the footprint corners togrid positions and use a pre-calculated lookup table to store the footprint coverage in weighting vectors. .......
Probem:Table has to be huge:
- here: M = 16
- 303,600 vectors with 16 entries each
- 4,857,600 bytes for 8-bit weights
