Description Retrieves the attributes of a particular Importance Sampling specification of type "Scatter rays toward a point".
Syntax ImpSampGetPos n, indx, angle, x, y, z, entity
Parameters n As Long Node number of the surface.
indx As Long The index (zero based) of the importance sampling specification.
angle As Double Returns the semi-angle (in degrees) of the solid angle cone.
x As Double Returns the X component of the position vector.
y As Double Returns the Y component of the position vector.
z As Double Returns the Z component of the position vector.
entity As Long Node number of the FRED entity whose coordinate system will be used to orient x, y, and z.
Remarks This subroutine retrieves the attributes of a particular Importance Sampling specification of type "Scatter rays toward a point". If the type is not Pos, or if there is another problem, the subroutine returns without modifying the parameters or setting an error.
