Graphics Analysis: GTX-RD
Screen space operations performed by graphics.
Object-space to screen-space transform on host.
Can easily become CPU bound.
- “Roughly 100 single-precision floating point operations are required to transform, light, clip test, project and map an object-space vertex to screen-space.” - K. Akeley & T. Jermoluk
Beware of fast-path and slow-path issues.
