Vertex Blending
Automatic keyframe animation in the graphics pipe
- The graphics pipeline takes two vertices and blends their positions to create an interpolated geometry
- The application can create “key-frames” and then instruct the graphics pipeline to interpolate between them
- Allows the CPU to generate only one frame in N
- The graphics pipe maintains its maximum output frame rate
- No CPU or FSB load for interpolated frames
- Application creates keyframes as display lists which can be DMA’d directly from memory
Two key frames DMA’s from system memory
