Controlling Rendering

Manage or query an OpenGL rendering context:

GLXContext glXCreateContext (Display *dpy, XVisualInfo *vis, GLXContext shareList, Bool direct);

void glXDestroyContext (Display *dpy, GLXContext ctx);

void glXCopyContext (Display *dpy, GLXContext src, GLXContext dst, GLuint mask);

Bool glXIsDirect (Display *dpy, GLXContext ctx);

Bool glXMakeCurrent (Display *dpy, GLXDrawable draw, GLXContext ctx);

GLXContext glXGetCurrentContext (void);

GLXDrawable glXGetCurrentDrawable (void);

Perform off-screen rendering:

GLXPixmap glXCreateGLXPixmap (Display *dpy, XVisualInfo *vis, Pixmap pixmap);

void glXDestroyGLXPixmap (Display *dpy, GLXPixmap pix);

Synchronize execution:

void glXWaitGL (void);

void glXWaitX (void);

Exchange front and back buffers:

void glXSwapBuffers (Display *dpy, Window window);

Use an X font:

void glXUseXFont (Font font, int first, int count, int listBase);
