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.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,

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