black outs

[enkeli]

The world contains 8 avatars and 8 lines ( see http://www.worldviz.com/forum/showthread.php?t=570 as to how I made the lines ). There is a timer that makes the lines update every tenth of a second so that they are aligned with where each avatar head is looking. When the screen blacks out, it's entirely black, can't see anything. The camera viewpoint has been in several locations about the room when it has blacked out. I've moved around (using the mouse) while it's blacked out and I will end up in a new place when it's no longer blacked out, but the simple moving doesn't seem to stop it. I did not have this problem with this world prior to adding the gaze lines. Therefore, I'm guessing the black outs have something to do with the program not being able to handle updating the lines so frequently.

Perhaps there is a better way to indicate the gaze of the avatars?
