Hi, There is an error in bounds calculation (minX, maxX, minY, maxY, minZ, maxZ) for ObjectContainer3D: it does not take into account its children transformations.
Proposal: ------------- It would help moving Entity's "bounds" property (and related protected methods) to ObjectContainer3D and adding a "transformBy(m : Matrix3D) : BoundingVolumeBase" method to BoundingVolumeBase class. This method would perform the provided transformation against the aabb vertices (aabbPoints) and calculate the bounds of the resulting box. Then in "updateBounds" method I whould add child.bounds.transformBy(child.transform) to calculate transformed aabb of each child in the loop for getting the min max in parent's coordinates. Regards.
