3D extents

Does anyone know of a method to calculate the extents for all 3D objects in a scene?
So I want x_min,x_max........z_max calculated by comparing each solid after any transformations.

you may use bounding spheres too. bounding sphere's radius remain same after object rotation, and you only need to translate the center of the sphere for translation . Here is a discussion on GameDev. There is an article on last post for implementation of sphere trees.
