Hi Robert, attached pls find a cleaned up version of the game of life example.
The example illustrates, using Conway's game of life [1], how to do flip-flop (aka ping-pong) rendering using two textures and FBOs. It uses two branches, each with a camera, one of which is selected during a rendering pass [2].
[1] http://en.wikipedia.org/wiki/Conway's_Game_of_Life [2] This is not the only (or fastest) way to do it, but an easy way in OSG. Run with e.g. osggameoflife --startim Images/land_shallow_topo_2048.jpg rgds jp --This message is subject to the CSIR's copyright terms and conditions, e-mail legal notice, and implemented Open Document Format (ODF) standard.
