    Re: glGetString(GL_EXTENSIONS_15);

    Chemdog, first of all, I'd like to inform you that the American Medical Association recommends that you smoke no more than three crack pipes a day.

    Second, extensions are not maintained forever....

    Re: Non decorated OpenGL programs..

    Re: Simplify

    I just wanted to say that I think Jared makes some excellent points here.

    Here's a possible compromise on the stippling issue. Make stippling undefined (or define it to be ignored) if vertex or...

    Re: api - GPU function speed

    It sounds like you're describing not an API, but a library. If it were an API, and the details were implimentation dependent, then the results would be inconsistent across different implementations...

    What kind of logic is that? I don't hear driver developers complaining about stippling (or the fixed function pipeline, for that matter). I only hear a few programmers who use GL for games...

    First of all, I use stippling in some of my software, which I'm developing for my dissertation, to draw dotted and dashed lines on a graph. Line stippling is NOT just the same as 1-D texturing; in...

    Re: Could do with some advanced help!

    First of all, I imagine that most people on the advanced board have gotten/are getting a degree. You're not the only one in the world to have gone to college.

    Huh? I thought it only took a few CPU cycles to read from and write to RAM. I would think that with the overhead of switching between threads, you wouldn't save any cycles.

    Re: glRotate(), precision points

    There's another option that's often overlooked: don't use glRotate*() at all. If you look at the spec, you will find the exact formula that this function is supposed to use. Just calculate the...

    Re: Vertical text in OpenGL/Win32

    Are you saying that you got text to draw with the individual characters rotated, but in a horizontal line? I didn't know you could do that. If that's the case, you could write a function that draws...

    Re: problem w/ depth sorting

    I believe the usual way to do object depth sorting is to tranform the objects' center coordinates by the modelview matrix and then sort them by their transformed z values. If you are using...

    Wrong. If you're looking for absolute best shader performance at any price, you want to avoid ATI and nVidia. Get some $10000 card from 3dLabs. But I don't think that's what jcabeleira is looking...
