HMD view warp

[Goof]

I'm using an nVisor SX60, but any viewed image is slightly warped.

That is, straight lines at the top of the screen bend into a "smile" shape, while straight lines near the bottom bend into a "frown", and the same effect on the sides, like the opposite of an image seen through a fisheye lens.

This causes all sorts of scene warping as you view a 3d scene with the headset on. This happens when simply viewing the desktop through the HMD as well.

What could this be? An issue with the HMD? An optical illusion? We have two, both have the same issues.

Are you using an nvis command to configure the display output in Vizard or adding the nvis display through vizconnect? Try the following test script:

import viz
import nvis

viz.go(viz.FULLSCREEN)
nvis.nvisorSX()

gallery = viz.addChild('piazza.osgb')

Generally I just use viz.go(viz.FULLSCREEN|viz.STEREO) to send the image to the HMD.

Tried the test script, it has the same effect.

I also used viz.fov() and changed the field of view, but that didn't get rid of the warping either.

Is it just the shape of the lenses?

Since this happens with any image I would suggest contacting nvis support for suggestions.
