    Re: Informal Forum Posting Guidelines: Commentary

    Dear Alfonse Reinhart, a.k.a Korval.

    Condescending tripe constitutes 80% of your text. The rest is half obvious, half valid mixed bad.

    The bright side is that in near future the state of GL will be less of pain for one reason: we will migrate most part of our renderers out of it. The only things still done with GL...

    Depth-only FBO would fail to pass validation without that code.

    Re: Depth FBO problem

    I experienced problems with depth-only FBO too. Maybe it's related to yours, or maybe it isn't.

    My problem is sensitive to combination of HW and driver:

    Yes, however it needs to be mentioned that graphics APIs ensure that ordering of polygons is preserved, which has effect on blending results. Such conservative rule would be quite new in GPGPU APIs. ...

    Keeping them separate as they are today, means there is no single API that would expose entire GPU to programmer. Todays 3D graphics APIs and GPGPU APIs have large functionality overlap, but each...

    Never mind then. Another possiblity for trivial bug: did you take into account the negative Z axis direction in eye space? GL uses different convention than DX.

    I'm using a texture to store indices, which then I use to access certain indexed resource in shader. Sort of permutation. And I'm using it to render shadows, not GPGPU stuff.

    I do care. If you try to use ordinary texture to store integer data, you are entering gray area. Say, you are using 8-bit per component texture format. To unpack sampled value to integer range in...
