Geometry Engine & Triangle Bus
- Intel i860XP,50MHz,100Mflops
- 2 Mbytes of combined code/data DRAM, 1 AS/C
- Code programming
>> Code is first developed in C, cross compiled for i860XP
>> Code that is executed frequently is then re-coded in i860XP assembly code.
- Treat each parameter as a plane equation, compute signed slope in the positive X and Y screen directions.
- Decompose all polygon to triangles
-Handle over 1 million triangles
-Broadcast rasterization data, point, line segment, texture images.
