Description
This procedure determines the point on the nurbs curve at the given u value in the indexed piece.
The index is zero based (0 to number of knots - 1). The u value can range from 0 to the value of the last knot in the curve segment.
PROCEDURE NurbsCurveEvalPt(
objectHd :HANDLE;
index :LONGINT;
u :REAL;
VAR pX,pY,pZ :REAL);
def vs.NurbsCurveEvalPt(objectHd, index, u): return p
Parameters
objectHd HANDLE Handle to a NURBS curve. index LONGINT Segment of curve to be queried. u REAL Parameter between the minimum and maximum knot value. p REAL Location of the u point on the curve.
