I am writing a simple game using cl-opengl (a pacman clone) and would like to have my game event loop call the rendering loop. I know freeglut enables a notion like this with glutMainLoopEvent. Is there any way to do the equivalent in cl-opengl ? I did run across the special variable *run-main-loop-after-display* - but it doesnt seem to take any effect. setting this variable to nil still causes the quad in render-to-texture to rotate - am i missing something ?
