3D stereo: problem with depth perception

[asimbh]

Hi,
I’m trying to achieve depth perception using Trivisio Stereo goggles however facing difficulty in doing so.
Up to now I’ve tried all display modes such as viz.STEREO|viz.FULLSCREEN, viz.STEREO|viz.HMD, etc. In addition I used all types of settings such as dualview, horizontal span, etc. but nothing worked. I can see the two shifted views but am not getting the 3D depth perception.
Furthermore, I’ve played with all the parameters as:
viz.stereooverlap(1),viz.fov(24, 1.33),viz.ipd(0.06),viz.viewdist(10), etc

I was wondering if there’s some trouble shooting or way of achieving depth perception. The environment I’m working on consists of VRML/3DS models of car assembly. By the way I've checked all the forums and tried the suggestions before posting that thread.
