Function Documentation

computeSurfaceDistances() [1/6]

MRMESH_API VertScalars MR::computeSurfaceDistances	(	const Mesh &	mesh,
		const HashMap< VertId, float > &	startVertices,
		float	maxDist = FLT_MAX,
		const VertBitSet *	region = nullptr,
		int	maxVertUpdates = 3 )

computes path distances in mesh vertices from given start vertices with values in them, stopping when maxDist is reached; considered paths can go either along edges or straightly within triangles

computeSurfaceDistances() [2/6]

MRMESH_API VertScalars MR::computeSurfaceDistances	(	const Mesh &	mesh,
		const MeshTriPoint &	start,
		const MeshTriPoint &	end,
		const VertBitSet *	region = nullptr,
		bool *	endReached = nullptr,
		int	maxVertUpdates = 3 )

computes path distance in mesh vertices from given start point, stopping when all vertices in the face where end is located are reached;

considered paths can go either along edges or straightly within triangles

Parameters

endReached

if pointer provided it will receive where a path from start to end exists
