Functions

template<typename CompressionT, typename PointDataGridT, typename PositionArrayT, typename PointIndexGridT>
PointDataGridT::Ptr createPointDataGrid (const PointIndexGridT &pointIndexGrid, const PositionArrayT &positions, const math::Transform &xform, const Metadata *positionDefaultValue=nullptr)
 Localises points with position into a PointDataGrid into two stages: allocation of the leaf attribute data and population of the positions.
 
template<typename CompressionT, typename PointDataGridT, typename ValueT>
PointDataGridT::Ptr createPointDataGrid (const std::vector< ValueT > &positions, const math::Transform &xform, const Metadata *positionDefaultValue=nullptr)
 Convenience method to create a PointDataGrid from a std::vector of point positions.
 
template<typename PointDataTreeT, typename PointIndexTreeT, typename PointArrayT>
void populateAttribute (PointDataTreeT &tree, const PointIndexTreeT &pointIndexTree, const openvdb::Name &attributeName, const PointArrayT &data, const Index stride=1, const bool insertMetadata=true)
 Stores point attribute data in an existing PointDataGrid attribute.
 
template<typename PositionAttribute, typename PointDataGridT, typename FilterT = NullFilter>
void convertPointDataGridPosition (PositionAttribute &positionAttribute, const PointDataGridT &grid, const std::vector< Index64 > &pointOffsets, const Index64 startOffset, const FilterT &filter=NullFilter(), const bool inCoreOnly=false)
 Convert the position attribute from a Point Data Grid.
 
template<typename TypedAttribute, typename PointDataTreeT, typename FilterT = NullFilter>
void convertPointDataGridAttribute (TypedAttribute &attribute, const PointDataTreeT &tree, const std::vector< Index64 > &pointOffsets, const Index64 startOffset, const unsigned arrayIndex, const Index stride=1, const FilterT &filter=NullFilter(), const bool inCoreOnly=false)
 Convert the attribute from a PointDataGrid.
 
template<typename Group, typename PointDataTreeT, typename FilterT = NullFilter>
void convertPointDataGridGroup (Group &group, const PointDataTreeT &tree, const std::vector< Index64 > &pointOffsets, const Index64 startOffset, const AttributeSet::Descriptor::GroupIndex index, const FilterT &filter=NullFilter(), const bool inCoreOnly=false)
 Convert the group from a PointDataGrid.
