- .SH NAME
- CRVPTDST
-
-
-
- NumericType CRVPTDST( CurveType Crv, PointType Point, NumericType IsMinDist,
- NumericType Epsilon )
-
- or
-
- ListType CRVPTDST( CurveType Crv, PointType Point, NumericType IsMinDist,
- NumericType Epsilon )
-
- Computes the closest (if IsMinDist is TRUE, farthest if FALSE) point
- on Crv to Point.
- Since this operation is partially numeric, Epsilon is used to set
- the needed accuracy. It returns the parameter value of the location on
- Crv closest to Point.
- If, however, Epsilon is negative, -Epsilon is used instead,
- and all local extrema in the distance function are returned as a list
- (both minima and maxima).
-
- Example:
-
- Param = CRVPTDST( Crv, Pt, FALSE, 0.0001 );
-
- finds the farthest point on Crv from point Pt.
