NAME
SymbCrv2DCurvatureSign()
SYNOPSIS
symb_lib/curvatur.c:351
CagdCrvStruct *SymbCrv2DCurvatureSign(CagdCrvStruct *Crv)
DESCRIPTION
Computes a scalar curve representing the curvature sign of a planar curve.
The given curve is assumed to be planar and only its x and y coordinates
are considered.
Then the curvature sign is equal to
. .. . ..
s = X Y - Y X
