NAME

BspCrvInterpPtsError()

SYNOPSIS

cagd_lib/cbsp_int.c:294

CagdRType BspCrvInterpPtsError(CagdCrvStruct *Crv,
                               CagdPtStruct *PtList,
                               CagdParametrizationType ParamType,
                               CagdBType Periodic)

DESCRIPTION

Given a set of points, and a curve least square fitting them using the BspCrvInterpPts function, computes an error measure as a the maximal distance between the curve and points (L1 norm).

PARAMETERS:

Crv: Curve that was fitted to the data set.

PtList: The data set.

ParamType: Parameter values at with curve should interpolate PtList.

Periodic: Constructed curve should be Periodic. Periodic necessitates uniform knot sequence in ParamType.

FUNCTION RETURN VALUE

CagdRType: Error measured in the L1 norm.
