NAME
SymbLclDistCrvPoint()
SYNOPSIS
symb_lib/distance.c:116
CagdPtStruct *SymbLclDistCrvPoint(CagdCrvStruct *Crv,
CagdPType Pt,
CagdRType Epsilon)
DESCRIPTION
Given a curve and a point, find the local extremum distance points on the
curve to the given point.
Returned is a list of parameter value with local extremum.
Computes the zero set of (Crv(t) - Pt) . Crv'(t).
PARAMETERS:
Crv: The curve to find its extreme distance locations to Pt.
Pt: The point to find the extreme distance locations from Crv.
Epsilon: Accuracy of computation.
FUNCTION RETURN VALUE
CagdPtStruct *: A list of parameter values of extreme distance
locations.
