Description Computes the vector field using an analysis surface and returns the results to an ARN. Incoherent or Coherent unpolarized rays are ignored. 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 numRays = VectorFieldToARN( anaNode, arnName, arnNode )
Parameters numRays (Long or Huge_) Number of rays included in the analysis.
anaNode As Long Node number of the analysis surface to be used in the analysis. The analysis surface's ray filters are applied.
arnName As String Name of the ARN being created.
arnNode As Long Node number of the newly created ARN. Returned by the function.
Remarks The following example performs an energy density calculation on an existing rayset.
Dim anaNode As Long Dim arnNode As Long Dim numRays As Long
anaNode = FindFullName( "Analysis Surface(s).Analysis 1" ) numRays = VectorFieldToARN( anaNode, "Example ARN", arnNode )
Multiple wavelengths When a coherent field calculation encounters multiple wavelengths, the calculation will proceed using only the first wavelength which satisfies the ray filter criteria. A warning dialog will be displayed which provides the wavelength range and the value used in the calculation (to 7 significant digits). All other wavelengths are ignored.
