    BTW, is there info available somewehre about current and previous HW generation (at least for NVidia and ATI) post-transform vertex cache sizes?

    Re: Official feedback on OpenGL 3.1 thread

    Haven't got the chance to download the specs yet, but what about the fixed function pipeline? Is it still in there or have it been eventually removed?

    Re: glGetMinmax, FBOs, and HDR textures

    So you suggest to calculate the min/max values based on ping-ponging between 2 textures?

    I already do that with success, but I thought the glGetMinmax() function could do that more efficiently...

    LUMINANCE32F and ...16F FBOs on ATI?

    Does ATI support LUMINANCE32F and ...16F color attachments for FBOs? After reading back the content after rendering into the FBO, all values are clamped to [0, 1]. The same code works as expected...
  11. Re: performance using glDrawElements or glArrayElement

    Use also a vertex array for your normals. Yes, you have to replicate each normal 4 times to match the vertices they belong to. And best would be to pad them with a 4th (unused float) to align the...

    Re: "GL_Static_Draw" doesn't work

    Use 4 byte color instead and take care of 16, 32 or 64 byte alignment of your vertex data; e.g., for position and color only use something like:



    struct VertexData {
    Vector3f pos; // 12...
