OpenGL testing, part 3

This time for sure. Please give this a whirl:

    test-texture3.c
    gcc -o test-texture3 test-texture3.c -I/usr/X11R6/include -L/usr/X11R6/lib -lX11 -lGL -lGLU -lm

<LJ-CUT text="It should look like this:">

It should look like this:

Please tell me whether it looks right, and what it printed to stdout.

If at all possible, try it on a variety of machines and in a variety of bit depths. Also try running on one machine and displaying on another.

I'm reasonably certain that some of you lied to me last time, so please be careful! If the text that says "RED" is not red, that's wrong! Perhaps it would be easier if you look at the rainbow at the bottom (ROYGBIV = red orange yellow green blue indigo violet, for those of you who have been out of elementary school for a while.)

I haven't gotten any responses from folks running in packed-24 or TrueColor-8, so if you can manage that, it would be helpful. I'm pretty sure one can coax SGIs to do those, at least.

Don't worry if the font size is off; it's just the colors that matter.

    Think an O2 will do it? I hope I've got a compiler on mine, else I'll pass. I'm not ready to face the hell that is inst anytime soon.

    • lifftchi says:

      What, you don't like inst? I mean, have you /tried/ other package managers? As far as I'm concerned, inst just works, and it works great.

      • en_ki says:

        My eyelid is twitching savagely. I hope you're happy.

      • valentwine says:

        Gotta say I agree. Inst still sucks, but it mostly sucks less. I've got a couple hundred machines running via RoboInst like gangbusters, and I can bring the freaking things all the way to the PROM to do updates from the comfort of my office if I want to. Contrast that with the amount of time and effort involved in running our RedHat machines using RPM and up2date. Linux can eat a bowl of dick.

        Inst is one of the things I was hoping SGI might open source. I should send somebody email about that. Not even apt has got RoboInst-like functionality.

        i tweaked your code slightly to get that last line. unfortunately i don't think OES_read_format is available in anything except Mesa CVS yet.

        glsnake, glblur and glforrestfire all work. glmatrix creates a window, kills the window and fails with error message:

        Other gl programs like glxgears and glxinfo work.

    Texture: ??? UNSIGNED_INT_8_8_8_8 0

    Needs a math.h include and -lm to compile on IRIX. Also, I was getting a BadMatch exception when trying to run it. Specifying a value of '0' for depth in the call to XCreateWindow() doesn't work on Xsgi. I changed that arg to vi->depth and it worked. If I get a minute (or even better if you get a minute) we could whip up some glXChooseVisual() hoodoo that'll cycle through every available visual (18 on this Octane!) and ask Yes or No.

    • valentwine says:

      Also, hooray for real X servers.

    • valentwine says:

      Just figured out why 0 doesn't work in the XCreateWindow() call: xdpyinfo(1) reports visual 0x2b:

      visual:
      visual id: 0x2b
      class: TrueColor
      depth: 15 planes
      available colormap entries: 32 per subfield
      red, green, blue masks: 0x1f, 0x3e0, 0x7c00
      significant bits in color specification: 8 bits

      The root window is running in visual 0x2d:

      visual:
      visual id: 0x2d
      class: TrueColor
      depth: 24 planes
      available colormap entries: 256 per subfield
      red, green, blue masks: 0xff, 0xff00, 0xff0000
      significant bits in color specification: 8 bits

      depth 0 to XCreateWindow is CopyFromParent. The hoodoo in your program that chooses a visual ends up with 0x2b from Xsgi, and then asks it to CopyFromParent for the depth, which is 24 bits and unsupported by the 0x2b visual. If I were running the root window at Xsgi's default depth of 8 I'd never have noticed. Probably why SGIs still ship with a root window depth of 8, so CopyFromParent always succeeds no matter what the application does. Ow. X.
