Detailed Description

template<typename _TreeT, typename _DenseT = Dense<typename _TreeT::ValueType>>
class openvdb::v12_0::tools::CopyFromDense< _TreeT, _DenseT >

Copy the values from a dense grid into an OpenVDB tree.

Values in the dense grid that are within a tolerance of the background value are truncated to inactive background voxels or tiles. This allows the tree to form a sparse representation of the dense grid.

Note

Since this class allocates leaf nodes concurrently it is recommended to use a scalable implementation of new like the one provided by TBB, rather than the mutex-protected standard library new.
