- Don't forget about aliasing as well. A simple approach to removing
- aliasing from your synthesized images is to "supersample" the scene
- and downfilter the supersampled image to the desired resolution. This
- is how many high-performance anti-aliasing hardware works -- by
- supersampling.
-
- Sampling theory indicates that you should increase the resolution by at
- least a factor of two.
-
- Also, don't forget that if you're rendering for video the color gamuts
- of RGB monitors and NTSC are not the same. Make sure your colors fit
- inside the NTSC gamut and that they are still distinguishable in NTSC
- space if they need to be visually different..
