Description Computes the Intensity on Polar Grid using a directional analysis entity and returns the results to an ARN. If the analysis surface provided is not a DAE, an error message is returned and the operation is halted. 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 = IntensityToARN( anaNode, arnName, arnNode )
Parameters numRays (Long or Huge_) Number of rays included in the analysis.
anaNode As Long Node number of the DAE to be used in the analysis. The DAE'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 Intensity calculation on an existing rayset using a DAE.
Dim daeNode As Long Dim arnNode As Long Dim numRays As Long
daeNode = FindFullName( "Analysis Surface(s).Analysis 1" ) numRays = IntensityToARN( daeNode, "Example ARN", arnNode )
