MR_PointCloudComponents_getAllComponents()

MRC_API MR_expected_std_pair_std_vector_MR_VertBitSet_int_std_string * MR_PointCloudComponents_getAllComponents	(	const MR_PointCloud *	pointCloud,
		float	maxDist,
		const int *	maxComponentCount,
		MR_PassBy	pc_pass_by,
		MR_std_function_bool_from_float *	pc )

gets all components of point cloud connected by a distance no greater than

Parameters

maxDist

\detail if components number more than the maxComponentCount, they will be combined into groups of the same size

Note

be careful, if point cloud is large enough and has many components, the memory overflow will occur

Parameters

maxComponentCount

should be more then 1

Returns

pair components bitsets vector and number components in one group if components number more than maxComponentCount Generated from function MR::PointCloudComponents::getAllComponents. Parameter pointCloud can not be null. It is a single object. Parameter maxComponentCount has a default argument: 2147483647, pass a null pointer to use it. Parameter pc has a default argument: {}, pass MR_PassBy_DefaultArgument and a null pointer to use it. Never returns null. Returns an instance allocated on the heap! Must call MR_expected_std_pair_std_vector_MR_VertBitSet_int_std_string_Destroy() to free it when you're done using it.

MR_PointCloudComponents_getLargeComponents()

MRC_API MR_expected_std_vector_MR_VertBitSet_std_string * MR_PointCloudComponents_getLargeComponents	(	const MR_PointCloud *	pointCloud,
		float	maxDist,
		int	minSize,
		MR_PassBy	pc_pass_by,
		MR_std_function_bool_from_float *	pc )

returns vector of point cloud components containing at least minSize points and connected by a distance no greater than

Parameters

maxDist

minSize

must be more than 1 Generated from function MR::PointCloudComponents::getLargeComponents. Parameter pointCloud can not be null. It is a single object. Parameter pc has a default argument: {}, pass MR_PassBy_DefaultArgument and a null pointer to use it. Never returns null. Returns an instance allocated on the heap! Must call MR_expected_std_vector_MR_VertBitSet_std_string_Destroy() to free it when you're done using it.

MR_PointCloudComponents_getLargeComponentsUnion_MR_PointCloud()

MRC_API MR_expected_MR_VertBitSet_std_string * MR_PointCloudComponents_getLargeComponentsUnion_MR_PointCloud	(	const MR_PointCloud *	pointCloud,
		float	maxDist,
		int	minSize,
		MR_PassBy	pc_pass_by,
		MR_std_function_bool_from_float *	pc )

returns the union of point cloud components containing at least minSize points and connected by a distance no greater than

Parameters

maxDist

minSize

must be more than 1 Generated from function MR::PointCloudComponents::getLargeComponentsUnion. Parameter pointCloud can not be null. It is a single object. Parameter pc has a default argument: {}, pass MR_PassBy_DefaultArgument and a null pointer to use it. Never returns null. Returns an instance allocated on the heap! Must call MR_expected_MR_VertBitSet_std_string_Destroy() to free it when you're done using it.

MR_PointCloudComponents_getLargeComponentsUnion_MR_UnionFind_MR_VertId()

MRC_API MR_expected_MR_VertBitSet_std_string * MR_PointCloudComponents_getLargeComponentsUnion_MR_UnionFind_MR_VertId	(	MR_UnionFind_MR_VertId *	unionStructs,
		const MR_VertBitSet *	region,
		int	minSize,
		MR_PassBy	pc_pass_by,
		MR_std_function_bool_from_float *	pc )

returns the union of vertices components containing at least minSize points

Parameters

unionStructs

prepared point union structure

Note

have side effect: call unionStructs.roots() that change unionStructs Generated from function MR::PointCloudComponents::getLargeComponentsUnion. Parameter unionStructs can not be null. It is a single object. Parameter region can not be null. It is a single object. Parameter pc has a default argument: {}, pass MR_PassBy_DefaultArgument and a null pointer to use it. Never returns null. Returns an instance allocated on the heap! Must call MR_expected_MR_VertBitSet_std_string_Destroy() to free it when you're done using it.

MR_PointCloudComponents_getUnionFindStructureVerts()

MRC_API MR_expected_MR_UnionFind_MR_VertId_std_string * MR_PointCloudComponents_getUnionFindStructureVerts	(	const MR_PointCloud *	pointCloud,
		float	maxDist,
		const MR_VertBitSet *	region,
		MR_PassBy	pc_pass_by,
		MR_std_function_bool_from_float *	pc )

Parameters

region

maxDist

Generated from function MR::PointCloudComponents::getUnionFindStructureVerts. Parameter pointCloud can not be null. It is a single object. Parameter region defaults to a null pointer in C++. Parameter pc has a default argument: {}, pass MR_PassBy_DefaultArgument and a null pointer to use it. Never returns null. Returns an instance allocated on the heap! Must call MR_expected_MR_UnionFind_MR_VertId_std_string_Destroy() to free it when you're done using it.
