public IProbeIntegrator.Result IntegrateOcclusion(IDeviceContext context, int positionOffset, int positionCount, int sampleCount, int maxLightsPerProbe, BufferSlice<int> perProbeLightIndices, BufferSlice<float> probeOcclusionEstimateOut)
Parameters
Device context.
Offset measured from the beginning of the probe position buffer.
Number of probes to integrate.
Number of samples to take.
Maximum number of lights per probe. The value must be 4.
Buffer slice containing the per probe light indices.
Buffer slice to write the probe occlusion estimate into. The size of the buffer in bytes should be maxLightsPerProbe * sizeof(float).
Returns

Remarks
The integrator does spherical sampling for each probe position. Occlusion is 1 if all rays hit front-facing triangles or the sky. Occlusion is 0 if all rays hit back-facing triangles.
