Syntax

template<typename RealType>  
class TDynamicPointSet3

Remarks

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, 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.

Variables

  Type Name Description
Protected variable TDynamicAttributeSetBase< TDynamicPointSet3< RealType > > * BaseAttributeSet Base attribute set
Protected variable FRefCountVector VertexRefCounts Reference counts of vertex indices. Iterate over this to find out which vertex indices are valid.
Protected variable TDynamicVector< RealType > Vertices List of vertex positions
