How can I get the size of all scene nodes?

I want to put the target of my camera at the center of the total models which include many many scene nodes.

Should I scanning each scene node and its child node by myself? Or, Irrlicht has provided a function like this?

getRootSceneNode()->getTotalBoundingBox()

Thank you for your comments.

I guess you'll have to...

there is no function like getTotalBoundingBox()...

one solution would be to create a single mesh out of all the single meshes, for example with bitplane's CBatchingMesh !!!

Walk your scene graph (either iteratively or recursively). Add the transformed bounding box of each scene node that is not the root node to a bounding box. Then find the center of that bounding box.

En It seems that I have to do this.

Thank you Acki, vitek very much
