NAME

BspSrfKnotInsert()  

SYNOPSIS

cagd_lib/bspboehm.c:142

CagdSrfStruct *BspSrfKnotInsert(CagdSrfStruct *Srf,
                                CagdSrfDirType Dir,
                                CagdRType t)
 

DESCRIPTION

Returns a new surface refined at t (t is inserted as a new knot in Srf) in parametric directipn Dir. See BspCrvKnotInsert for the mathematical background of this knot insertion algorithm.  

PARAMETERS:

Srf: To refine by adding a new knot with value equal to t. If Srf is a periodic curve, it is first unwrapped to a float end condition curve.

Dir: Of refinement, either U or V.

t: New knot to insert into Srf.  

FUNCTION RETURN VALUE

CagdSrfStruct *: The refined surface.
