4 Q3NURBCurve_SetControlPoint

You can use the Q3NURBCurve_SetControlPoint function to set a four-dimensional control point for a NURB curve.

TQ3Status Q3NURBCurve_SetControlPoint (
TQ3GeometryObject curve, 
unsigned long pointIndex, 
const TQ3RationalPoint4D *point4D);
curve A NURB curve.
pointIndex An index into the controlPoints array of control points for the specified NURB curve.
point4D The desired four-dimensional control point.

DESCRIPTION


The Q3NURBCurve_SetControlPoint function sets the four-dimensional control point of the NURB curve specified by the curve parameter having the index in the array of control points specified by the pointIndex parameter to the point specified by the point4D parameter.
