Description Sets the values of an importance sampling specification of type "Scatter rays through a closed curve" on a surface.
Syntax ImpSampSetCurve n, indx, curve
Parameters n As Long Node number of the surface.
indx As Long The index (zero based) of the importance sampling specification.
curve As Long Sets the node number of the closed curve towards which the rays will scatter.
Remarks This subroutine sets on a surface the values of an importance sampling specification of type "Scatter rays through a closed curve". If the type was not previously "Curve", or if there is another problem, the subroutine sets an error and returns without modifying curve.
