- I don't get your point. Spatial anti-aliasing deals with the
- 2D image, which can be viewed as a projection of the 3D scene.
- Temporal anti-aliasing is otherwise known as motion-blurring.
- I don't see how extra quality can be achieved by further
- work that regards the dimensions as equivalent. That may be my
- problem!?
