You should know the extent of the object in all 3 dimensions, so you just define 8 vertices that create the box/cube around it. Then you just test for intersections with other objects. You could also test each vertice in your object, but that would take forever. This discussion came up before and the bounding box (or even a bounding cylinder) was sufficient. - e!
