Then, I should be able to find the center of those pixels as (x + (pixelWidth/2), y + (pixelWidth/2)), as shown below:
How do I implement something like pixelWidth/2? Also, I don’t understand what you mean in the second to last sentence “I think you could … camera as length of adjacent side of the triangle”; could you clarify?
Finally, the material graphs you linked to, are these supposed to be used in conjunction with the procedure described above? I’m not I follow how this is all supposed to come together.

Did you ever figure it out?
