Update Bounding Box in OpenGL libGDX

I currently have a few objects rotating around my 3D world. Each of them have a BoundingBox object associated with them. How do I update the bounding box values after calls to glRotate() and glTranslate()?

To do that you have to loop over every vertex, calculate it's position in the world (multiply by modelview) and find minimum / maximum vertex coordinates within every object (just like when you compute it for the first time).
