CSG Rendering Advantages
Ray-traced CSG is free from limitations of hardware polygon rendering:
- No approximate polygonal geometry.
- No seams, exact curvatures.
- Exact profile edges. Important for ATR!
- No level-of-detail switching, no “popping”.
- Full temperature range in Kelvins, not 0-255.
- Unlimited spectral resolution, not just 3 channels.
