AABBs with Irrlicht Scene Nodes

Well, I was just wondering, a very n00b question, but are the scene node bounding boxes recalculated every time you transform the node?

No, the box returned by getBoundingBox is an axis aligned bounding box, meaning they are relative to the transformation of the node. The transformed bounding box is transformed into world space every time it is requested, so this method is quite slow. See ISceneNode.h

Ah, okay, thanks bitplane. Yeah, I wasn't exactly sure where to look at first. I guess I should have known ISceneNode.
