using AccessorType = DefaultReadAccessor<BuildType> |
using LeafNodeType = typename RootT::LeafNodeType |
using Node0 = LeafNodeType |
Return the total number of active tiles at the specified level of the tree.
level = 1,2,3 corresponds to active tile count in lower internal nodes, upper internal nodes, and the root level. Note active values at the leaf level are referred to as active voxels (see activeVoxelCount defined above).
Return the total number of active voxels in this tree.
Return a const reference to the background value.
Return a const reference to the index bounding box of all the active values in this tree, i.e. in all nodes of the tree.
Sets the extrema values of all the active values in this tree, i.e. in all nodes of the tree.
