Member Function Documentation

accumulate()

MRMESH_API void MR::MeshOrPoints::accumulate	(	PointAccumulator &	accum,
		const AffineXf3f *	xf = nullptr ) const

Adds in existing PointAccumulator the elements of the contained object.

asMeshPart()

const MeshPart * MR::MeshOrPoints::asMeshPart ( ) const

inlinenodiscard

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

asPointCloud()

const PointCloud * MR::MeshOrPoints::asPointCloud ( ) const

inlinenodiscard

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

cacheAABBTree()

MRMESH_API void MR::MeshOrPoints::cacheAABBTree

(

)

const

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

computeBoundingBox()

MRMESH_API Box3f MR::MeshOrPoints::computeBoundingBox ( const AffineXf3f * toWorld = nullptr ) const

nodiscard

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()

MRMESH_API Box3f MR::MeshOrPoints::getObjBoundingBox ( ) const

nodiscard

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

limitedProjector()

MRMESH_API LimitedProjectorFunc MR::MeshOrPoints::limitedProjector ( ) const

nodiscard

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()

MRMESH_API std::function< Vector3f(VertId)> MR::MeshOrPoints::normals ( ) const

nodiscard

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

points()

MRMESH_API const VertCoords & MR::MeshOrPoints::points ( ) const

nodiscard

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

pointsGridSampling()

MRMESH_API std::optional< VertBitSet > MR::MeshOrPoints::pointsGridSampling ( float voxelSize, size_t maxVoxels = 500000, const ProgressCallback & cb = {} ) const

nodiscard

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

Parameters

maxVoxels;

returns std::nullopt if it was terminated by the callback

projector()

MRMESH_API std::function< ProjectionResult(const Vector3f &)> MR::MeshOrPoints::projector ( ) const

nodiscard

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

validPoints()

MRMESH_API const VertBitSet & MR::MeshOrPoints::validPoints ( ) const

nodiscard

gives access to bit set of valid points

weights()

MRMESH_API std::function< float(VertId)> MR::MeshOrPoints::weights ( ) const

nodiscard

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