I want a Matrix, Frustum or whatever, which produces a view that is nearly the same as a frustum (near objects are bigger than far away objects), but with the reverse of object sizes.

I will explain this as: nearer objects will be smaller than objects far away from the cam/eye, but only on screen, not in the “3d world”, so i need a matrix, that is nearly the same as the frustum produces but with near/far clipplanes swapped ??!

How to do such a calculation, without scale,translate, or other non-hardware accelerated functions ???

[I know that my english isn’t the best …]

Random guess coming up…

When calculating (the maths) the frustrum type matrix, negate the z for the vanishing point so it is in front of the opbject nstead of behind…
