Detailed Description

template<typename RealType>
class UE::Geometry::TDynamicPointSet3< RealType >

TDynamicPointSet3 implements a dynamic 3D point set, templated on real-value type (float or double). The points are indexed and the class allows for gaps in the index space.

The points are referred to as "Vertices" for consistency with higher-level Mesh and Graph classes. This class can be used interchangeably with the Vertices of those classes in some cases (for example in spatial data structures like TDynamicVerticesOctree3)

The point data is stored in via TDynamicVector<RealType>, which internally uses chunked storage and so is relatively efficient to grow/shrink/etc

Reference counts for the points are stored via a FRefCountVector instance

A per-point attribute set can optionally be attached. Currently the client is responsible for managing the memory for this attribute set. The attribute set will be automatically updated when points are added or removed.

Member Function Documentation

◆ AppendVertex()

template<typename RealType >

int UE::Geometry::TDynamicPointSet3< RealType >::AppendVertex ( const TVector< RealType > & Position )

inline

Append vertex at position, returns vid

◆ BeginUnsafeVerticesInsert()

template<typename RealType >

void UE::Geometry::TDynamicPointSet3< RealType >::BeginUnsafeVerticesInsert ( )

inline

Call this before a set of unsafe InsertVertex() calls

◆ Clear()

template<typename RealType >

void UE::Geometry::TDynamicPointSet3< RealType >::Clear ( )

inline

Discard all data

◆ CompactMetric()

template<typename RealType >

RealType UE::Geometry::TDynamicPointSet3< RealType >::CompactMetric ( ) const

inline

returns measure of compactness in range [0,1], where 1 is fully compacted

◆ EndUnsafeVerticesInsert()

template<typename RealType >

void UE::Geometry::TDynamicPointSet3< RealType >::EndUnsafeVerticesInsert ( )

inline

Call after a set of unsafe InsertVertex() calls to rebuild free list

◆ GetBaseAttributeSet()

template<typename RealType >

TDynamicAttributeSetBase< TDynamicPointSet3< RealType > > * UE::Geometry::TDynamicPointSet3< RealType >::GetBaseAttributeSet ( ) const

inline

◆ GetBounds()

template<typename RealType >

TAxisAlignedBox3< RealType > UE::Geometry::TDynamicPointSet3< RealType >::GetBounds ( ) const

inline

Returns bounding box of all points

◆ GetVertex()

template<typename RealType >

TVector< RealType > UE::Geometry::TDynamicPointSet3< RealType >::GetVertex ( int VertexID ) const

inline

Returns: the vertex position

◆ GetVerticesBuffer()

template<typename RealType >

const TDynamicVector< double > & UE::Geometry::TDynamicPointSet3< RealType >::GetVerticesBuffer ( )

inline

◆ GetVerticesRefCounts()

template<typename RealType >

const FRefCountVector & UE::Geometry::TDynamicPointSet3< RealType >::GetVerticesRefCounts ( )

inline

◆ InsertVertex()

template<typename RealType >

EMeshResult UE::Geometry::TDynamicPointSet3< RealType >::InsertVertex	(	int	VertexID,
		const TVector< RealType > &	Position,
		bool	bUnsafe = `false`
	)

inline

Insert vertex at given index, assuming it is unused. If bUnsafe, we use fast id allocation that does not update free list. You should only be using this between BeginUnsafeVerticesInsert() / EndUnsafeVerticesInsert() calls

◆ IsCompact()

template<typename RealType >

bool UE::Geometry::TDynamicPointSet3< RealType >::IsCompact ( ) const

inline

Returns: true if vertex count == max vertex id

◆ IsVertex()

template<typename RealType >

bool UE::Geometry::TDynamicPointSet3< RealType >::IsVertex ( int VertexID ) const

inline

Returns: true if VertexID is a valid vertex in this point set

◆ MaxVertexID()

template<typename RealType >

int UE::Geometry::TDynamicPointSet3< RealType >::MaxVertexID ( ) const

inline

Returns: upper bound on vertex IDs used in the point set, ie all vertex IDs in use are < MaxVertexID

◆ RemoveVertex()

template<typename RealType >

EMeshResult UE::Geometry::TDynamicPointSet3< RealType >::RemoveVertex ( int VertexID )

inline

Remove point

◆ SetExternallyManagedAttributes()

template<typename RealType >

void UE::Geometry::TDynamicPointSet3< RealType >::SetExternallyManagedAttributes ( TDynamicAttributeSetBase< TDynamicPointSet3< RealType > > * AttributeSet )

inline

◆ SetVertex()

template<typename RealType >

void UE::Geometry::TDynamicPointSet3< RealType >::SetVertex	(	int	VertexID,
		const TVector< RealType > &	vNewPos
	)

inline

Set vertex position

◆ VertexCount()

template<typename RealType >

int UE::Geometry::TDynamicPointSet3< RealType >::VertexCount ( ) const

inline

Returns: number of vertices in the point set

◆ VertexIndicesItr()

template<typename RealType >

FRefCountVector::IndexEnumerable UE::Geometry::TDynamicPointSet3< RealType >::VertexIndicesItr ( ) const

inline

Returns: enumerable object for valid vertex indices suitable for use with range-based for, ie for ( int i : VertexIndicesItr() )

◆ VerticesItr()

template<typename RealType >

FRefCountVector::MappedEnumerable< TVector< RealType > > UE::Geometry::TDynamicPointSet3< RealType >::VerticesItr ( ) const

inline

Enumerate positions of all points
