Stereo HUD and Nvis SX111

[kopper]

Hi, I am trying to set up a Vizard application to display in our Nvis SX111 using the NVis module:

nvis.nvisorSX111()


Everything looks fine, except some HUD information that I display using screen coordinates, which causes the HUD to appear as double images when looking through the HMD, since the screen coords are the same for both eyes.

My question is how can I make Vizard display a HUD in SX111 (or any partial overlap stereo HMD, for that matter)?

I tried changing the viz.stereoHUD in vizcore.cfg, but that just caused the HUD to be displayed in a single eye.

In other words, what I need is for an orthogonal projection to be able to display in a partially overlapping HMD seamlessly. The way I imagine this could be done would be to account for the partial overlap, and display the same HUD graphics in the overlapping portions, and the respective graphics in each of the non-overlapping portions of the display. However, I don't think I can access directly each eye image from the NVis module, and I hope there is a more straight forward way to achieve this.

Any help is appreciated.

Thank you,

Regis
