NAME

BzrSrf2Polygons()

SYNOPSIS

cagd_lib/bzr2poly.c:45

CagdPolygonStruct *BzrSrf2Polygons(CagdSrfStruct *Srf,
                                   int FineNess,
                                   CagdBType ComputeNormals,
                                   CagdBType FourPerFlat,
                                   CagdBType ComputeUV)

DESCRIPTION

Routine to convert a single Bezier surface to set of triangles approximating it. FineNess is a fineness control on result and the larger is more triangles may result. A value of 10 is a good start value. NULL is returned in case of an error, otherwise list of CagdPolygonStruct.

PARAMETERS:

Srf: To approximate into triangles.

FineNess: Control on accuracy, the higher the finer.

ComputeNormals: If TRUE, normal information is also computed.

FourPerFlat: If TRUE, four triangles are created per flat surface. If FALSE, only 2 triangles are created.

ComputeUV: If TRUE, UV values are stored and returned as well.

FUNCTION RETURN VALUE

CagdPolygonStruct *: A list of polygons with optional normal and/or UV parametric information. NULL is returned in case of an error.
