[Papervision3D] Animating camera to target

[eric mcconkie]

nice get/set extension...this is awesome...thanks! You have saved me a ton of headache...or at least resolved so many issues....BUT, it seems to only work with prmitives...correct? I ask because i stacked a bunch of planes into a do3D, but get an error when i try:

trace((dodd.geometry.aabb.maxY - dodd.geometry.aabb.minY)*dodd.scaleY);

happy to help.
i use a custom class called SmartPlane instead of Plane
which has width and height properties
i have attached it. enjoy.
