Parameters

bufferIn Microsoft.DirectX.Direct3D.PrtBuffer
A PrtBuffer object that represents the 3-D object from the previous light bounce. This input buffer must have the proper number of color channels allocated for the simulation.
sampleLocations Microsoft.DirectX.Vector3[]
Number of sample locations.
sampleNormals Microsoft.DirectX.Vector3[]
Position for each sample.
bufferOut Microsoft.DirectX.Direct3D.PrtBuffer
A PrtBuffer object that models the direct lighting contribution to the point, using the spherical harmonic (SH) approximation. This output buffer must have the proper number of color channels allocated for the simulation.
dataComputed Microsoft.DirectX.Direct3D.PrtBuffer
A PrtBuffer object that is the running sum of all previous bufferOut outputs.
