    That was about one year ago. The report still says "in progress" so I didn't checked if the problem was solved because I workarounded it (a nasty choice but the only available one) and I won't go...

    My main problems where with NVidia. I reported the bugs in their developer section->report bugs. My reports soon passed from "in queue" to "reproduced, work in progress"

  5. Compute Shaders, current support by companies

    Hello,

    I would like to know, from someone that had used extensively, or at least in some degree, the Compute Shaders, what's the current state of the drivers.
    During the past two years I was...

    I've found the problem as far I understood the specification, but of course I could be wrong.

    Now, I'm using these interface block in the 3 stages

    Ok, found the problem.
    Although the specification says that:

    in Material {
    smooth in vec4 Color1; // legal, input inside in block
    smooth vec4 Color2; // legal, 'in' inherited from 'in Material'...
  8. Interpolation qualifiers in interface blocks

    Hello,

    I'm playing with geometry shaders, so I have to use interface blocks for vertex attributes. I haven't find much documentation about this (perhaps I missed the line in the specs) so I'm a...

    Re: Shader and program binary loading

    Well, the specs are the first doc I start with when I try to learn a new feature (specially when its a really new feature and there still doesnt exists online tutorials), then I search for tutorials...

    Re: Shader and program binary loading

    Hi,

    I'm a little confused on this topic too. Reading the specs I'd found a way to RETRIEVE/LOAD PROGRAM binaries but I'd only found a way to LOAD SHADER binaries. It's expected that the way of...
  11. Re: extract translation/ euler rotation from modelview

    This depends on the order in which you perform the operations. Try printing the result of S * T and the result of T * S

    Edit: I answered in a two months old thread, nice. Sorry for the up.

    Re: Case sesitive Functions???

    C programming language is case sensitive, so OpenGL is too. Of course i suppose that you are using C, but most languages are case sensitive.

    Re: Outlined OpenGl text like Google earth

    If you ONLY want render text like in the google earth's image, use a bitmap with all characters into. It's far the easiest, faster (and simplest) way to render text, moreover if you have to render...

    Re: shader program link error with no info log

    Could you be more explicit? Doed the shaders compilation throw any error? Are your shader handles valid handles? That kind of information would be useful.

    Re: weird ...

    I bet my right hand that this is a bad memory access in your vertex buffers. Check them again: size, number of vertices, number of vertex components, types...

    Re: Barrel/pincushion distortion

    The easiest way is painting a quad with the texture, and apply your distortion calculation within the fragment shader. Because barrel distortion is not linear (it usually has spherical and tangential...

    Re: Use a texture from another application

    Perhaps this is too obvious, but its worth to ask. Are you sure that the texture you want share is created after the wglShareLists call?

    Re: I want to learn GLSL....

    Try these tutorials. Now they are a vit outdated, because they relies on first GLS version, but they are usable and you can understand the whole thing using them.

    Re: GL_ATI_texture_compression_atitc

    You are right, I've complained too fast. Well, at least now I'm sure that both extensions are the same (first one was never released, but renamed as the second)

    For the current time, I only need...

    @ZBuffer, Android relies on OpenGL|ES.
