computeDistanceMap()

meshlib.mrmeshpy.DistanceMap mrcudapy.computeDistanceMap	(	meshlib.mrmeshpy.Mesh	mesh,
		meshlib.mrmeshpy.MeshToDistanceMapParams	params,
		meshlib.mrmeshpy.func_bool_from_float	cb = '{}',
		meshlib.mrmeshpy.std_vector_MeshTriPoint	outSamples = None )

computes distance (height) map for given projection parameters
using float-precision for finding ray-mesh intersections, which is faster but less reliable

computeDistanceMapHeapBytes()

int mrcudapy.computeDistanceMapHeapBytes	(	meshlib.mrmeshpy.Mesh	mesh,
		meshlib.mrmeshpy.MeshToDistanceMapParams	params,
		bool	needOutSamples = False )

Computes memory consumption of computeDistanceMap function

computeSkyViewFactor()

meshlib.mrmeshpy.VertScalars mrcudapy.computeSkyViewFactor	(	meshlib.mrmeshpy.Mesh	terrain,

		meshlib.mrmeshpy.std_vector_SkyPatch	skyPatches,
		meshlib.mrmeshpy.BitSet	outSkyRays = None,
		meshlib.mrmeshpy.std_vector_MeshIntersectionResult	outIntersections = None )

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;
\\param 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
\\param outIntersections - optional output vector of MeshIntersectionResult for every valid sample point

distanceMapFromContours()

meshlib.mrmeshpy.DistanceMap mrcudapy.distanceMapFromContours	(	meshlib.mrmeshpy.Polyline2	polyline,

distanceMapFromContoursHeapBytes()

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