NAME

BspCrv2Polyline()

SYNOPSIS

cagd_lib/bsp2poly.c:596

CagdPolylineStruct *BspCrv2Polyline(CagdCrvStruct *Crv,
                                    int SamplesPerCurve,
                                    BspKnotAlphaCoeffType *A,
                                    CagdBType OptiLin)

DESCRIPTION

Routine to approx. a single Bspline curve as a polyline with SamplesPerCurve samples. Polyline is always E3 CagdPolylineStruct type. Curve is refined equally spaced in parametric space, unless the curve is linear in which the control polygon is simply being copied. If A is specified, it is used to refine the curve. NULL is returned in case of an error, otherwise CagdPolylineStruct.

PARAMETERS:

Crv: To approximate as a polyline.

SamplesPerCurve: Number of samples to approximate with.

A: Alpha matrix (Oslo algorithm) if precumputed.

OptiLin: If TRUE, optimize linear curves.

FUNCTION RETURN VALUE

CagdPolylineStruct *: A polyline representing the piecewise linear approximation from, or NULL in case of an error.
