WASDEQ - move camera Arrow keys - rotate camera 4 - move player I wanted to see how a bloom lighting effect (around the edges of triangles, walls etc) would look. In this case I made it create several blue circle gradients around the edges of some black walls. It looks OK, but not great... it's incredibly clone/stamp expensive... and it would be really hard to program the bloom lighting so that you wouldn't have to input the positions manually and that it would always work for all triangle/wall positions... So I think it's not worth it to use this technique when making games. Maybe only in a few special cases.
