Steals all nodes of a certain type from the tree and adds them to a container with the following API:
An example of a wrapper around a c-style array is:
An example that constructs a list of pointer to all leaf nodes is:
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, |
const bool | preserveTiles = false |
||
) |
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.
