virtual camera, real camera

of course, aligning the virtual camera of the 3D scene with the real camera’s capture of the actual scene was never going to be straightforward. easy to get to a proof of concept. hard to actually register the two. i ended up rendering a cuboid grid on the seat positions in the 3D scene, drawing by hand (well, mouse) what looked about right on a video still, and trying to match the two sets of lines by nudging coordinates and fields-of-view with some debug-mode hotkeys i hacked in.

in hindsight, i would have stuck motion capture markers on the cameras. so it goes.
