Say i have a 3D rectangle, rotated 45 degrees as in the attached screenshot. I would like the lines and the far edge (A) to look fading. Moreover, when i rotate the camera, i want the 'new' far lines and edges to look fading. So if B will be in the place if A, B and the lines to B will look fading. How can i do that?
If it makes any difference, i use OpenGL ES 2.0 on iOS.
