An improved z-buffer CSG rendering algorithm
Nigel Stewart, Geoff Leach, Sabu John · 1998
We present an improved z-buffer based CSG rendering algorithm, based on previous techniques using z-buffer parity based surface clipping.We show that while this type of algorithm has been reported as requiring O(n2), (where n is the number of primitives), an O(lcn) (where k is depth complexity) algorithm may be substituted.For cases where k is less than n this translates into a significant performance gain.
