Stereo problems on 3D monitor

[timbo]

My program takes information from a tracker and shows the hand position of the person by displaying a green ball in the environment. I want this to look as 3 dimensionally as possible so using an ipd value of zero just wont work. I set it to the average ipd value of 0.06 and two separate green balls apear next to eachother. Then I messed with the fusion distance so the center of my environment was the center window but whenever I moved away from this position the two balls appear and get larger abnd larger apart as the hand moves away from the original window. What else should I try to solve this problem? Thanks
