IritTrimSrfsToCubicBzrCrvs()

SYNOPSIS

prsr_lib/ip_cnvrt.c:974

CagdCrvStruct *IritTrimSrfsToCubicBzrCrvs(TrimSrfStruct *TrimSrfs,
                                          IPPolygonStruct **CtlMeshes,
                                          CagdBType DrawTrimSrf,
                                          CagdBType DrawMesh,
                                          int NumOfIsolines[2],
                                          CagdRType MaxArcLen)

DESCRIPTION

Approximates an arbitrary list of trimmed surfaces into cubic Beziers curves. Only isoparametric curves are extarcted (no trimming curves).

PARAMETERS:

TrimSrfs: To approximate as cubic Bezier curves.

CtlMeshes: If we want control meshes as well (DrawMesh == TRUE) they will be placed herein.

DrawTrimSrf: Do we want to draw the surfaces?

DrawMesh: Do we want to draw the control meshes?

NumOfIsolines: Number of isocurves to extract, in each direction.

MaxArcLen: Tolerance for cubic Bezier approximation. See function BzrApproxBzrCrvAsCubics.

FUNCTION RETURN VALUE

CagdCrvStruct *: The cubic Bezier approximation, or NULL if DrawSurface is FALSE.
