| Animation 
Animation is rendering/moving - rendering/moving ...
   
 Most OpenGL hardware provide double-buffering
to facilitate animation.
One frame is visible (front buffer) while the back buffer
is being drawn
Changing front and back buffers is implementation dependent
void glXSwapBuffers( Display *dpy, Window window);
void glutSwapBuffers(void); |
