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.
