Csg algorithm

WebAn algorithm is presented for constructing shadow volumes for CSG objects. For each primitive solid, the algorithm calculates a tree of shadow volumes to model the shadows generated by the shadow-generating parts of the boundary of the primitive. The shadow of the complete CSG object is the union of these shadow trees. An implementation of the … WebAlgorithm Solve ray intersection for each primitive. Result is an (possibly empty) interval for each primitive. Apply the CSG set operations on the intervals on the ray. Keep track of the nearest point.
