Scan line coherence algorithm
Webspan coherence- values don't change much from pixel to pixel in a span scanline coherence - values don't change much from one scanline to the next - the coverage (or visibility) of a face on one scanline typically differs little from the previous one. edge coherence - edges intersected by scanline i are typically intersected by scanline i+1 WebAbstract. Scan-line algorithms for visibility calculation exploit various types of coherence properties. Several scan-line algorithms for Constructive Solid Geometry (CSG) are …
