OpenGL maximum point_size


    Feb 16 2009 | 12:36 pm
    Hi, I'm currently trying to make a spotlight which will run over a projector using OpenGL (so i can control focus, intensity and position of the light). However it seems that point_size maxes out at around 256. I'd like to illuminate the whole OpenGL window with this one 'point' (/spot) and be able to focus in on a very small area.
    Is this possible?
    If not I've considered having a second layer underneath the spotlight and as the spot increases in size the second layer brightens and when focused on one area it's black. This should mean that i could illuminate the whole OpenGL window that way, but seems a bit hacky.
    Thanks
    Lou

      Hello list! I was wandering if anyone implemented the Diffusion Limited Aggregation algorithm in jitter: http://www.gut-wirtz.de/dla/ Is there in the list anyone who already used that algorithm within max? tnx,
