Node::InvalidateNode

Invalidates the world transform and dependent information.

void InvalidateNode(void);

The InvalidateNode function should be called whenever a node's local transform is altered through the Node::SetNodeTransform function or one of the associated functions that alters only part of the local transform. When a node is invalidated, it is queued to be updated the next time the World Manager processes the scene before rendering. When a node is updated, its world transform is recalculated, and if needed, its world-space bounding box and world-space bounding sphere are recalculated.

Invalidating a node causes its entire subtree to be invalidated, so it is not necessary to call the InvalidateNode function for each node in the subtree if many transforms are changed. Calling the InvalidateNode function for the highest node in a hierarchy is sufficient.
