Member Function Documentation

addPartByMask()

None meshlib.mrmeshpy.PointCloud.addPartByMask	(		self,
		PointCloud	from_,
		VertBitSet	fromVerts,
		CloudPartMapping	outMap = 'MR::CloudPartMapping{}',
		VertCoords	extNormals = None )

appends points (and normals if it possible) (from) in addition to this points
if this obj have normals and from obj has not it then don't do anything
\\param extNormals if given then they will be copied instead of from.normals

addPoint() [1/2]

VertId meshlib.mrmeshpy.PointCloud.addPoint	(		self,
		Vector3f	point )

appends a point and returns its VertId

addPoint() [2/2]

VertId meshlib.mrmeshpy.PointCloud.addPoint	(		self,
		Vector3f	point,
		Vector3f	normal )

appends a point with normal and returns its VertId

calcNumValidPoints()

int meshlib.mrmeshpy.PointCloud.calcNumValidPoints

(

self

)

computes the total number of valid points in the cloud

computeBoundingBox()

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

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

findCenterFromBBox()

Vector3f meshlib.mrmeshpy.PointCloud.findCenterFromBBox

(

self

)

computes bounding box and returns its center

findCenterFromPoints()

Vector3f meshlib.mrmeshpy.PointCloud.findCenterFromPoints

(

self

)

computes average position of all valid points

flipOrientation()

None meshlib.mrmeshpy.PointCloud.flipOrientation	(		self,
		VertBitSet	region = None )

flip orientation (normals) of given points (or all valid points is nullptr)

getAABBTree()

AABBTreePoints meshlib.mrmeshpy.PointCloud.getAABBTree

(

self

)

returns cached aabb-tree for this point cloud, creating it if it did not exist in a thread-safe manner

getAABBTreeNotCreate()

AABBTreePoints meshlib.mrmeshpy.PointCloud.getAABBTreeNotCreate

(

self

)

returns cached aabb-tree for this point cloud, but does not create it if it did not exist

getBoundingBox()

Box3f meshlib.mrmeshpy.PointCloud.getBoundingBox

(

self

)

returns the minimal bounding box containing all valid vertices (implemented via getAABBTree())

getLexicographicalOrder()

std_vector_Id_VertTag meshlib.mrmeshpy.PointCloud.getLexicographicalOrder

(

self

)

returns all valid point ids sorted lexicographically by their coordinates (optimal for uniform sampling)

getVertIds()

VertBitSet meshlib.mrmeshpy.PointCloud.getVertIds	(		self,
		VertBitSet	region )

if region pointer is not null then converts it in reference, otherwise returns all valid points in the cloud

hasNormals()

bool meshlib.mrmeshpy.PointCloud.hasNormals

(

self

)

returns true if there is a normal for each point

heapBytes()

int meshlib.mrmeshpy.PointCloud.heapBytes

(

self

)

returns the amount of memory this object occupies on heap

invalidateCaches()

None meshlib.mrmeshpy.PointCloud.invalidateCaches

(

self

)

Invalidates caches (e.g. aabb-tree) after a change in point cloud

mirror()

None meshlib.mrmeshpy.PointCloud.mirror	(		self,
		Plane3f	plane )

reflects the points from a given plane

normals() [1/2]

VertCoords meshlib.mrmeshpy.PointCloud.normals

(

self

)

unit normal directions of points (can be empty if no normals are known)

normals() [2/2]

None meshlib.mrmeshpy.PointCloud.normals	(		self,
		VertCoords	arg1 )

pack() [1/2]

VertBMap meshlib.mrmeshpy.PointCloud.pack	(		self,
		Reorder	reoder )

tightly packs all arrays eliminating invalid points, reorders valid points according to given strategy;
\\return points mapping: old -> new

pack() [2/2]

bool meshlib.mrmeshpy.PointCloud.pack	(		self,
		VertMap	outNew2Old = None )

tightly packs all arrays eliminating invalid points, but relative order of valid points is preserved;
returns false if the cloud was packed before the call and nothing has been changed;
if pack is done optionally returns mappings: new.id -> old.id

points() [1/2]

VertCoords meshlib.mrmeshpy.PointCloud.points

(

self

)

coordinates of points

points() [2/2]

None meshlib.mrmeshpy.PointCloud.points	(		self,
		VertCoords	arg1 )

validPoints() [1/2]

VertBitSet meshlib.mrmeshpy.PointCloud.validPoints

(

self

)

only points and normals corresponding to set bits here are valid

validPoints() [2/2]

None meshlib.mrmeshpy.PointCloud.validPoints	(		self,
		VertBitSet	arg1 )
