Detailed Description

Member Function Documentation
◆ get_data()
|
inline |
Returns the CullTraverserData in use at the time of the callback.
This object contains data that changes at each node of the traversal, such as the current node and the current net transform to that node.
Definition at line 40 of file nodeCullCallbackData.I.
◆ get_trav()
|
inline |
Returns the CullTraverser in use at the time of the callback.
This object contains data that does not change during the traversal, such as the DisplayRegion and Camera in use.
Definition at line 30 of file nodeCullCallbackData.I.
◆ upcall()
|
virtual |
You should make this call during the callback if you want to continue the normal rendering function that would have been done in the absence of a callback.
Specifically, this method will add this node to the draw queue, and continue the cull traversal for all the nodes below. If you omit this call, this node and its children will be pruned from the render result.
Reimplemented from CallbackData.
Definition at line 41 of file nodeCullCallbackData.cxx.
