void openvdb::OPENVDB_VERSION_NAME::Grid< TreeT >::topologyDifference ( const Grid< OtherTreeType > & other )

inline

Difference this grid's set of active values with the active values of the other grid, whose value type may be different.

After this method is called, voxels in this grid will be active only if they were active to begin with and if the corresponding voxels in the other grid were inactive.

Note: This operation can delete branches of this grid that overlap with active tiles in the other grid. Also, because it can deactivate voxels, it can create leaf nodes with no active values. Thus, it is recommended to prune this grid after calling this method.

void openvdb::OPENVDB_VERSION_NAME::Grid< TreeT >::topologyIntersection ( const Grid< OtherTreeType > & other )

inline

Intersect this grid's set of active values with the active values of the other grid, whose value type may be different.

The resulting state of a value is active only if the corresponding value was already active AND if it is active in the other tree. Also, a resulting value maps to a voxel if the corresponding value already mapped to an active voxel in either of the two grids and it maps to an active tile or voxel in the other grid.

Note: This operation can delete branches of this grid that overlap with inactive tiles in the other grid. Also, because it can deactivate voxels, it can create leaf nodes with no active values. Thus, it is recommended to prune this grid after calling this method.

template<typename TreeT >

void openvdb::OPENVDB_VERSION_NAME::Grid< TreeT >::topologyUnion ( const Grid< OtherTreeType > & other )

inline

Union this grid's set of active values with the active values of the other grid, whose value type may be different.

The resulting state of a value is active if the corresponding value was already active OR if it is active in the other grid. Also, a resulting value maps to a voxel if the corresponding value already mapped to a voxel OR if it is a voxel in the other grid. Thus, a resulting value can only map to a tile if the corresponding value already mapped to a tile AND if it is a tile value in the other grid.

Note: This operation modifies only active states, not values. Specifically, active tiles and voxels in this grid are not changed, and tiles or voxels that were inactive in this grid but active in the other grid are marked as active in this grid but left with their original values.
