inlineinherited

Copy from a dense grid into this node the values of the voxels that lie within a given bounding box.

dense	dense grid with a stride in z of one (see tools::Dense in tools/Dense.h for the required API)
background	background value of the tree that this node belongs to
tolerance	tolerance within which a value equals the background value

Note: bbox is assumed to be identical to or contained in the coordinate domains of both the dense grid and this node, i.e., no bounds checking is performed.; Consider using tools::CopyFromDense in tools/Dense.h instead of calling this method directly.
