I want to make an app that can share what is drawn on 1 window between multiple windows. So if I were to animate a ball in the 1st window from the left (0) to the right of the window (width) it would be drawn as the ball animating from the left side of the 1st window, though the 2nd and 3rd window, and to right side of the 4th window. I've read that this can be done using GLUT and FBOs but the examples I've found are for multiple windows which are not shared. How can this be done using either the core OpenGL/GLUT (PGraphicsOpenGL and etc) or GLGraphics drawing objects? Thanks!
