SYNOPSIS

cagd_lib/sbsp_int.c:214

CagdSrfStruct *BspSrfInterpolate(CagdCtlPtStruct *PtList,
                                 int NumUPts,
                                 int NumVPts,
                                 CagdRType *UParams,
                                 CagdRType *VParams,
                                 CagdRType *UKV,
                                 CagdRType *VKV,
                                 int ULength,
                                 int VLength,
                                 int UOrder,
                                 int VOrder)
 

DESCRIPTION

Given a set of points on a rectangular grid, PtList, parameter values the surface should interpolate or approximate these grid points, U/VParams, the expected two knot vectors of the surface, U/VKV, the expected lengths U/VLength and orders U/VOrder of the Bspline surface, computes the Bspline surface's coefficients. All points in PtList are assumed of the same type.  

PARAMETERS:

PtList: A long linked list (NumUPts * NumVPts) of points to interpolated or least square approximate.

NumUPts: Number of points in PtList in the U direction.

NumVPts: Number of points in PtList in the V direction.

UParams: Parameter at which surface should interpolate or approxximate PtList in the U direction.

VParams: Parameter at which surface should interpolate or approxximate PtList in the V direction.

UKV: Requested knot vector form the surface in the U direction.

VKV: Requested knot vector form the surface in the V direction.

ULength: Requested length of control mesh of surface in U direction.

VLength: Requested length of control mesh of surface in V direction.

UOrder: Requested order of surface in U direction.

VOrder: Requested order of surface in U direction.  

FUNCTION RETURN VALUE

CagdSrfStruct *: Constructed interpolating/approximating surface.
