    ok 10x but i need i was hoping for something more meaningful -
    and also I meant some program the utilizes the incoming fragment's Z value and not setting the output FragDepth.
  2. shading program the fiddles with Z values

    Hi all,
    i'm looking for an example of a shader program that changes the depth values, and also would appreciate a short explanation what kind of effects this can produce.

    thank you!

    i'm curious what will happen if I assign a render buffer (using glDrawBuffers for instance) to buffer #3, and fail to assign any value in my shader program to gl_FragData[3] -
    will the...
