Detailed Description

Generated from:  MR::MeshOrPoints

This class can hold either mesh part or point cloud.
It is used for generic algorithms operating with either of them

Member Function Documentation

accumulate()

None meshlib.mrmeshpy.MeshOrPoints.accumulate	(		self,
		PointAccumulator	accum,
		AffineXf3f	xf = None )

Adds in existing PointAccumulator the elements of the contained object

asMeshPart()

MeshPart meshlib.mrmeshpy.MeshOrPoints.asMeshPart

(

self

)

if this object holds a mesh part then returns pointer on it, otherwise returns nullptr

asPointCloud()

PointCloud meshlib.mrmeshpy.MeshOrPoints.asPointCloud

(

self

)

if this object holds a point cloud then returns pointer on it, otherwise returns nullptr

cacheAABBTree()

None meshlib.mrmeshpy.MeshOrPoints.cacheAABBTree

(

self

)

if AABBTree is already built does nothing otherwise builds and caches it

computeBoundingBox()

Box3f meshlib.mrmeshpy.MeshOrPoints.computeBoundingBox	(		self,
		AffineXf3f	toWorld = None )

passes through all valid vertices and finds the minimal bounding box containing all of them;
if toWorld transformation is given then returns minimal bounding box in world space

getObjBoundingBox()

Box3f meshlib.mrmeshpy.MeshOrPoints.getObjBoundingBox

(

self

)

returns the minimal bounding box containing all valid vertices of the object (and not only part of mesh);
implemented via obj.getAABBTree()

limitedProjector()

func_void_from_Vector3_float_MeshOrPoints_ProjectionResult meshlib.mrmeshpy.MeshOrPoints.limitedProjector

(

self

)

returns a function that updates projection (closest) points on this,
the update takes place only if res.distSq on input is more than squared distance to the closest point

normals()

func_Vector3_float_from_Id_VertTag meshlib.mrmeshpy.MeshOrPoints.normals

(

self

)

returns normals generating function: VertId->normal (or empty for point cloud without normals)

points()

VertCoords meshlib.mrmeshpy.MeshOrPoints.points

(

self

)

gives access to points-vector (which can include invalid points as well)

pointsGridSampling()

VertBitSet meshlib.mrmeshpy.MeshOrPoints.pointsGridSampling	(		self,
		float	voxelSize,
		int	maxVoxels = 500000,
		func_bool_from_float	cb = 'MR::ProgressCallback{}' )

performs sampling of vertices or points;
subdivides bounding box of the object on voxels of approximately given size and returns at most one vertex per voxel;
voxelSize is automatically increased to avoid more voxels than \\param maxVoxels;
returns std::nullopt if it was terminated by the callback

projector()

func_MeshOrPoints_ProjectionResult_from_Vector3_float meshlib.mrmeshpy.MeshOrPoints.projector

(

self

)

returns a function that finds projection (closest) points on this: Vector3f->ProjectionResult

validPoints()

VertBitSet meshlib.mrmeshpy.MeshOrPoints.validPoints

(

self

)

gives access to bit set of valid points

weights()

func_float_from_Id_VertTag meshlib.mrmeshpy.MeshOrPoints.weights

(

self

)

returns weights generating function: VertId->float:
for mesh it is double area of surrounding triangles, and for point cloud - nothing
