set 0 IOD to have synoptic view in HMD

[hzhao]

Hi,

I want to have synoptic view in my HMD, that is, two HMD screens provide the same image. In vizard, I set the IOD in to 0. But I still can see the difference between the two screen images. How can I get it? Thanks.

Can you post your code related to display and ipd setup?

viz.fov(53,1.1887)
viz.go(viz.STEREO | viz.FULLSCREEN)
view = viz.MainView
headTrack = viz.addSensor('intersense')
viz.link(headTrack, view)

This code is for vizard 3.0.
I create a virtual world with vizard and display it in a HMD. To get stereopsis, vizard displays different images on the two screens of the HMD. This is just like we see different scenes in our two eyes because of the distance between our eyes.
Now, I want to display the same image on the two screen of HMD. It is just like we see the same scene in our two eyes. And I suppose I can do this by set the distance between our two eyes to be 0.
How can I do this in vizard?
Thanks!

Use the viz.ipd command with a value of 0:
viz.fov(53,1.1887)
viz.go(viz.STEREO | viz.HMD)
viz.ipd(0)

The code works. Thank you!
