I had a quick look through the reference paper given above. All I can say is "good luck with that". If you can make head or tail from that lot figuring out how to make an OpenGl engine must be trivial😜

[quote=saam_b]...now in my program I have to convert this depth from texture coordinate to eye-space in my shader for further calculations. the problem is I don't know about the mathematics behind this and if someone can introduce a reference or expl

i doo that you ave saw. but i understand the problem: I have a block in my code that return an array of x and y coords for a section manager. The problem is that if i have the direction of the beam(a line) in the z coord i must take the y and z c
