TrimCrvs2Polylines()

SYNOPSIS

trim_lib/trim_aux.c:357

CagdPolylineStruct *TrimCrvs2Polylines(TrimSrfStruct *TrimSrf,
                                       CagdBType ParamSpace,
                                       int SamplesPerCurve,
                                       int Optimal)

DESCRIPTION

Routine to convert the trimming curves of a trimmed surface to polylines. Polyline are always E3 of CagdPolylineStruct type. NULL is returned in case of an error, otherwise list of CagdPolylineStruct.

PARAMETERS:

TrimSrf: To extract isoparametric curves from.

ParamSpace: TRUE for curves in parameteric space, FALSE of 3D Euclidean space.

SamplesPerCurve: Fineness control on piecewise linear curve approximation.

Optimal: Use optimal approximation of isocurves.

FUNCTION RETURN VALUE

CagdPolylineStruct *: List of polylines representing a piecewise linear approximation of the extracted isoparamteric curves or NULL is case of an error.
