Stereoscopic view question

[atamasan]

Hello.
I have a question. When I use HMD, I know I must use viz.go(viz.HMD).
I can see 3D objects through the HMD. And I know the "ipd" should be set because the value is different each person. So I changed the value to see the effect of ipd. I changed like this:
viz.ipd(.2)

But nothing changed. So, after that I tried again, like this.
viz.go(viz.STEREO|viz.HMD)
viz.ipd(.2)

This time(when I use viz.go(viz.STEREO|viz.HMD)), objects were rendered only right side of the window. What are the reasons for this? Please let me know.

PS I am using emagin's z800.

Thank you .

The viz.STEREO flag renders left and right eyes side by side. This is used for a device that works with passive stereo.

Try using the viz.QUAD_BUFFER flag if your graphics card supports quad buffered stereo.

Thank you very much for your advice.
O.K. I'll try using "viz.QUAD_BUFFER"

Thank you again.
