so, here's what i want to do:
I have an picture, i split it into a 10 x 10 grid, I then randomly move these tiles back/forward along the z axis. What i want to achieve is when the camera is looking down the z axis, the picture would look like it was in an ortho projection.
basically, what i need to know, is how to translate each tiles size and position, so that they perfectly align to a picture from only the one perspective.
also, i plan to rotate each tile to face the camera, i'm assuming to make this work, each tile well have to have a slight offset for looking at the camera, otherwise when i do align the camera in that one spot, all the tiles well be slighlty mis-aligned since their trying to look at the center point.
anyway, i need some pointers, the only thing i've found on this is: http://stackoverflow.com/questions/6962992/orthographic-to-perspective-adjustment-calculation but I can't figure out how to apply the information. I'm assuming it's because i'm not taking into account the view matrix?
right now i'm not worrying about rotating the camera, or rotating the tiles to face the camera, so my first step is trying to figure out how to make the tile's align and size correctly.
