numberRays System.Int32
Number of light rays to direct at each sample. Must be greater than zero.isUsingSphere System.Boolean
Set to true if samples will be computed over a full sphere. Set to false if samples will be computed over a hemisphere.isUsingCosine System.Boolean
Set to true to use a cosine weighting of samples. If both isUsingCosine and isUsingSphere are true, the method will fail.isAdaptive System.Boolean
Must be false. Adaptive sampling is currently not implemented.adaptiveThreshold System.Single
Ignored.
Exceptions
