Call the PruneOp
functor for each child node and, if the functor returns true
, prune the node and replace it with a tile.
This method is used to implement all of the various pruning algorithms (prune(), pruneInactive(), etc.). It should rarely be called directly.

Mark all values (both tiles and voxels) as active.

Overwrite each inactive value in this node and in any child nodes with a new value whose magnitude is equal to the specified background value and whose sign is consistent with that of the lexicographically closest active value.
This is primarily useful for propagating the sign from the (active) voxels in a narrow-band level set to the inactive voxels outside the narrow band.
Overwrite each inactive value in this node and in any child nodes with either outside or inside, depending on the sign of the lexicographically closest active value.
Specifically, an inactive value is set to outside if the closest active value in the lexicographic direction is positive, otherwise it is set to inside.

Return a pointer to the node of type NodeT
that contains voxel (x, y, z) and replace it with a tile of the specified value and state. If no such node exists, leave the tree unchanged and return NULL

void topologyDifference | ( | const InternalNode< OtherChildNodeType, Log2Dim > & | other, |
const ValueType & | background | ||
) |
Difference this node's set of active values with the active values of the other node, whose ValueType
may be different. So a resulting voxel will be active only if the original voxel is active in this node and inactive in the other node.
The last dummy argument is required to match the signature for InternalNode::topologyDifference.
|
inline |
void topologyIntersection | ( | const InternalNode< OtherChildNodeType, Log2Dim > & | other, |
const ValueType & | background | ||
) |
Intersects this tree's set of active values with the active values of the other tree, whose ValueType
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.
|
inline |
void topologyUnion | ( | const InternalNode< OtherChildNodeType, Log2Dim > & | other | ) |
Union this branch's set of active values with the other branch's active values. The value type of the other branch can 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 tree. 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 tree. 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 other tree.
Specifically, active tiles and voxels in this branch are not changed, and tiles or voxels that were inactive in this branch but active in the other branch are marked as active in this branch but left with their original values.

Return the leaf node that contains voxel (x, y, z). If no such node exists, create one, but preserve the values and active states of all voxels.
Use this method to preallocate a static tree topology over which to safely perform multithreaded processing.
