The Viewing Problem

The second form(a)

Given a view specification, and the coordinates of the points of a bunch of objects in the view volume, how can we transform the view volume and the objects in it to become the "standard" view volume?
Reduction to a previously solved problem
Still not easy

For a perspective view specification, we'll transform to a standard "perspective" view volume and then do one last clever step.
