- That was a good summary. One correction, though: the GX and GXPlus
- do hardware acceleration of 3D coordinate transformations, so they
- are *quite* speedy doing 3D wireframes, point clouds, and flat shading.
-
- They don't do hidden-surface removal or any advanced rendering operations
- (Phong shading, lighting calculations, texture mapping, etc)
- in hardware, so if you substitute "Photorealistic Rendering" for "3D" in
- the short version above, it becomes correct.
