StdPrs_HLRPolyShape Class Reference

Instantiates Prs3d_PolyHLRShape to define a display of a shape where hidden and visible lines are identified with respect to a given projection. StdPrs_HLRPolyShape works with a polyhedral simplification of the shape whereas StdPrs_HLRShape takes the shape itself into account. When you use StdPrs_HLRShape, you obtain an exact result, whereas, when you use StdPrs_HLRPolyShape, you reduce computation time but obtain polygonal segments. The polygonal algorithm is used.
