The -OpenGL functions: glReadPixels, glCopyPixels, and glCopyColorTable, -should use the readable drawable if it's different than the rendering -drawable. - -o glXGetProcAddress (a GLX 1.4 feature and ARB extension) - -glXGetProcAddress should work and allow getting the address of any -extension functions you may need from the X11 libGL, or OpenGL framework -libGL. Previous versions of the X11 libGL didn't allow getting the newer -OpenGL framework addresses. - -o GLXPixmaps - -New support for GLXPixmaps works well with mixed X11 and OpenGL drawing -operations. You can create them using glXCreateGLXPixmap or -glXCreatePixmap. - -o GLXPbuffers - -Support for GLXPbuffers has been added. These are drawables that are -not possible to render to with X11, which is allowed by the spec. -A GLXPbuffer will never generate a clobber event, however -glXSelectEvent and glXGetSelectedEvent should operate normally. - -Clobber events are not generated due to low-level architectural -differences. The contents of your pbuffers will not be clobbered. - -o Shared Contexts - -Due to basic low-level architectural differences the usage of shared -contexts requires a similar visual or GLXFBConfig be used in the -creation of a shared context. It's best if you specify the same -visual. This is due to a CGL design difference, and not something -that is easily worked around. UPDATE: some changes made seem to -help resolve this issue in many cases, so you may be able to use a -shared context without this restriction. - - -o Indirect - -The X server supports indirect fairly well, so OpenGL applications -can be run remotely and displayed by XQuartz. This means you can run -applications from a remote host on an XQuartz X server. - -AppleSGLX does not support indirect rendering. Any indirect context -created will appear to glXIsDirect as an indirect context, but it -does not actually support indirect rendering to a remote X server. - -AppleSGLX supports GLXPixmaps and GLXPbuffers with direct and indirect -contexts, though they are all direct contexts by definition (see above). |
