GetPointAndParameterOnNurbsCurveAtGivenLength

Description

Gets point, parametric parameter, and curve index of specified location along a NURBS Curve.

FUNCTION GetPointAndParameterOnNurbsCurveAtGivenLength(
				inNurbCurve       : HANDLE;
				inPercentOfLength : REAL;
				VAR pX,pY,pZ      : REAL;
				VAR outParam      : REAL;
				VAR outIndex      : LONGINT): BOOLEAN;
def vs.GetPointAndParameterOnNurbsCurveAtGivenLength(inNurbCurve, inPercentOfLength):
    return (BOOLEAN, p, outParam, outIndex)

Parameters

Name Type Description
inNurbCurve HANDLE Handle to the NURBS curve.
inPercentOfLength REAL Specify location on curve as percent of total length. (0 - 1)
p REAL Point of specified location.
outParam REAL Parametric parameter of location.
outIndex LONGINT 0-based index of piece for piecewise NURBS curve.

Examples

VectorScript
