NAME
SymbSrfIsoDirNormalCurvatureBound()
SYNOPSIS
symb_lib/curvatur.c:1141
CagdSrfStruct *SymbSrfIsoDirNormalCurvatureBound(CagdSrfStruct *Srf,
CagdSrfDirType Dir)
DESCRIPTION
Computes normal curvature bound in given isoparametric direction.
This turns out to be (L11 . n) / G11 for u and (L22 . n) / G22 for v.
Herein the square of these equations is computed symbolically and
returned.
PARAMETERS:
Srf: To compute normal curvature in an isoparametric direction Dir.
Dir: Direction to compute normal curvature. Either U or V.
FUNCTION RETURN VALUE
CagdSrfStruct *: A scalar field representing the normal curvature
square of Srf in dirction Dir.
