Description Sets the ray direction data for a source with a single direction plane wave ray direction type.
Syntax SetSourceDirection n, dirA, dirB, dirC
Parameters n As Long Node number of the source.
dirA As Double The new X component of the direction vector.
dirB As Double The new Y component of the direction vector.
dirC As Double The new Z component of the direction vector.
Remarks This subroutine sets the ray direction data from a source with a single direction plane wave ray direction type. If there is a problem the function returns without modifying the source or setting an error.
