I would suggest Rune's ILLUSION.INC include file (with some minor changes.) I
don't know whether that's 'available' or what his license terms are, though.

It's essentially a different mapping type for image_maps--'camera projection' or
'camera mapping.' There's nothing like it in POV-Ray at present, AFAIK (and is a
feature available in many high-end CG programs.) I don't know if Rune is
actively engaged in updating his file; if not, I would certainly be willing to
help improve it with some slight changes (though necessary ones, IMO.) I've
already done that for my own use.

In lieu of that, maybe a (*gulp!*) feature request along the same lines:
possibly as the so-far-unused map_type 4. Rune's code *seems* to be an SDL
method for simply eliminating/reversing part of the 'transform' that POV-Ray
internally applies to an image_map to project it onto objects in
space--'eliminating' the z-distance/perspective pixel transformation. (Turning
it back into solely an affine transform? Sorry, my knowledge of this is
sketchy.) ANYWAY, just an idea.
