Function Documentation

MR_Cuda_computeSkyViewFactor()

MRC_CUDA_API MR_VertScalars * MR_Cuda_computeSkyViewFactor	(	const MR_Mesh *	terrain,
		const MR_VertCoords *	samples,
		const MR_VertBitSet *	validSamples,
		const MR_std_vector_MR_SkyPatch *	skyPatches,
		MR_BitSet *	outSkyRays,
		MR_std_vector_MR_MeshIntersectionResult *	outIntersections )

computes relative radiation in each valid sample point by emitting rays from that point in the sky: the radiation is 1.0f if all rays reach the sky not hitting the terrain; the radiation is 0.0f if all rays do not reach the sky because they are intercepted by the terrain;

Parameters

outSkyRays

- optional output bitset where for every valid sample #i its rays are stored at indices [i*numPatches; (i+1)*numPatches), 0s for occluded rays (hitting the terrain) and 1s for the ones which don't hit anything and reach the sky

outIntersections

- optional output vector of MeshIntersectionResult for every valid sample point Generated from function MR::Cuda::computeSkyViewFactor. Parameter terrain can not be null. It is a single object. Parameter samples can not be null. It is a single object. Parameter validSamples can not be null. It is a single object. Parameter skyPatches can not be null. It is a single object. Parameter outSkyRays defaults to a null pointer in C++. Parameter outIntersections defaults to a null pointer in C++. Never returns null. Returns an instance allocated on the heap! Must call MR_VertScalars_Destroy() to free it when you're done using it.

MR_Cuda_findSkyRays()

MRC_CUDA_API MR_BitSet * MR_Cuda_findSkyRays	(	const MR_Mesh *	terrain,
		const MR_VertCoords *	samples,
		const MR_VertBitSet *	validSamples,
		const MR_std_vector_MR_SkyPatch *	skyPatches,
		MR_std_vector_MR_MeshIntersectionResult *	outIntersections )

In each valid sample point tests the rays from that point in the sky;

Returns

bitset where for every valid sample #i its rays are stored at indices [i*numPatches; (i+1)*numPatches), 0s for occluded rays (hitting the terrain) and 1s for the ones which don't hit anything and reach the sky

Parameters

outIntersections

- optional output vector of MeshIntersectionResult for every valid sample point Generated from function MR::Cuda::findSkyRays. Parameter terrain can not be null. It is a single object. Parameter samples can not be null. It is a single object. Parameter validSamples can not be null. It is a single object. Parameter skyPatches can not be null. It is a single object. Parameter outIntersections defaults to a null pointer in C++. Never returns null. Returns an instance allocated on the heap! Must call MR_BitSet_Destroy() to free it when you're done using it.
