How to use stereoscopic rendering for CAVE systems
I want to render a Unity scene in a CAVE.
In theory Unity should have everything needed now:
Multi screen rendering
Stereoscopic rendering
Off axis projection
The problem is stereoscopy is only a flag in the settings and thus kind of a black box. I guess it wont work as expected if I use an off axis projection matrix for the camera. Is there anyway to get more control over the stereoscopy effect or maybe create 2 cameras myself and use them for each eye?
What kind of control are you looking for?
The way we do it is to build with stereoscopic support and use the Camera SetStereoView$$anonymous$$atrices and SetStereoProjection$$anonymous$$atrices to setup the asymmetric view frustums each frame. That used to be enough but now you also have to run with -vrmode stereo on the command line.
Note: we're using the OpenGL API. I've never tested on DX.
It seems like this is exactly the control I was looking for. I really didnt know those methods exist. Thx for pointing it out. I'll try it as soon as possible.
