Description Sets the coherence state of a specific ray. 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 SetRayCoherent id, coherent
Parameters id As Long (or Huge_) The identifier of the ray.
coherent As T_RAYCOHERENT Structure containing the new coherent specification for the ray.
Remarks This subroutine sets the coherency state of a specific ray. Specifically it allows you to set the phase curvatures and 1/e Gaussian field amplitude widths of the coherent ray. If there is a problem the subroutine sets an error and returns without modifying the ray.
