template<typename PredicateFunc, typename IterateFunc>
void FindNodesWithPredicate
&40;
const PredicateFunc & Predicate,
const IterateFunc & Func
&41; const
Remarks
This function will traverse the Octree starting from the root in depth first order and the predicate can be used to implement custom culling for each node.
Parameters
| Name | Description |
|---|---|
| Predicate | a Function when given the bounds of the currently traversed node that returns true if traversal should continue or false to skip that branch. |
| Func | Function that will receive the node ID which can be stored and later used to get the elements using GetElementsForNode for all nodes that passed the predicate. |
