Description Retrieves the coherency state for a specific ray in the ray buffer. 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 coh = IsCoherent ( id )
Parameters coh (Boolean) Will be set to True if the ray is coherent, False if it is not.
id As Long (or Huge_) Identifier for the ray.
Remarks This function retrieves the coherency state for a specific ray in the ray buffer. If there is a problem, the function posts an error and returns False.
