Detailed Description

template<typename PointIndexGridType = PointIndexGrid>
struct openvdb::v13_0::tools::ParticleAtlas< PointIndexGridType >::Iterator

Provides accelerated range and nearest-neighbor searches for particles that are partitioned using the ParticleAtlas.

Note

Prefer to construct the iterator object once and reuse it for subsequent queries.
