Description Modifies an importance sampling specification with type "Scatter rays toward an ellipsoidal volume" on a surface.
Syntax ImpSampSetEllipsoid n, indx, ellipse
Parameters n As Long Node number of the surface.
indx As Long The index (zero based) of the importance sampling specification.
ellipse As T_IMPSAMPELLIPSOID Structure used to set the new data for the ellipsoid.
Remarks This subroutine modifies an importance sampling specification with type "Scatter rays toward an ellipsoidal volume" on a surface. If the type was not previously Ellipsoid, or if there is another problem, the subroutine sets an error and returns without modifying the importance sampling specification.
