Description Deletes one user ray from a specified source with user ray positions. Depending on the number of rays traced, it may be necessary to dimension ray index and ray counter variables as data type Huge_ instead of Long. Please see Multi-threaded Raytracing for more information.
Syntax raysLeft = DeleteSourceIthUserRay ( n, rayNum )
Parameters raysLeft (Long or Huge_) The number of rays left after the function finishes.
n As Long Node number of the source.
rayNum As Long (or Huge_) The index (zero based) of the ray to be deleted from the user defined rays specification.
Remarks This function deletes one user ray from a specified source. If there is a problem the function returns -1 and does not set an error. Calling this function is functionally the same as calling DeleteSourceUserRays with a count argument of 1.
