i dont know if that means anything though.
Well, that means that your Mesa version implements this function as an extension, although it should be in the OpenGL 1.2 core. You can simply use that instead of the plain glBlendEquation.
also i was wondering if using nm on libGL.so is a good way to see if glBlendEquation is present.
Not really.
i was also thinking of creating a tiny program that made a call to glBlendEquation and determining from the success or failure of its compilation whether glBlendEquation was present. is this a good way to do it?
Yes, that's the standard way of doing it and autoconf already has macros for that purpose. The only tricky part is getting the include paths and linker flags right for the test, so you should do this *after* the detection of the OpenGL flags already in configure.in.
[...] a few examples dont seem to work right. Feedback draws a corner and a dot and then gives this
Xlib: unexpected async reply (sequence 0x33)!
they seem to correspond to window manager events. ie if i click on another window and then click on the feedback window to bring it back to the top it will print the same message with a different hex number. switching desktops will also do this as does shading and then unshading the feedback window.
Hmmm, I've never seen this before. Feedback should draw what you described and then print a bunch of lines "GL_FOO_BAR_TOKEN" plus some numbers. Does anybody out there have a clue?
Wrap gives the message created glx context but then nothing happens
Huh? What printed that message?
Trim informs me that trimming hasnt been implemented yet. it displays some kind of round tile thing.
That's because your Mesa version is not feature-complete. A "full" OpenGL implementation would draw something like folded shirt.
and several of the examples could use better ui :) it took me awhile to figure out how to operate robot, the planet one, and the torus.
"Use the source, Luke!" :-)
anyway since it seems to generally work i will be writing a portfile for it on freebsd (hopefully oliver braun will help me ensure that it is done right :)
Fine. Cheers, S.
