Calculate angles to render 3D actor as an affine-transform sprite
For a bit of background: I'm working on a tech demo for the Gameboy Advance, where I'm using pre-rendered backgrounds - combined with a 3D navmesh, and a camera matrix - to place actors into the scene. Because the GBA doesn't have any 3D hardware, my plan is to pre-render the actors from many different angles (eg. 8 angles around the global up/down axis, and 4 angles around the global left/right axis), and then choosing the correct angles for display. Note that rotation about the camera z axi
