[Chromium-users] Rendering for stereoscopic and reassembly for headset

[Eric S. <er...@sa...>]

Hello Chromium users and developers,

I am trying to use Chromium to display left-/right-eye stereoscopic =20
outputs on four machines via projectors and a fifth master hooked to a =20
headset. The headset takes a resolution of 1696x480 (848x480 for each =20
'eye') and the resolution of the stereoscopic projectors is 1400x1024 =20
for each projector.

Setup:
vr-master: Visual Research V8 headset
slave1: left side/left eye
slave2: right side/left eye
slave3: left side/right eye
slave4: right side/right eye

I am using a modified tiles.conf configuration file (attached) and our =20
configuration file (vrcim.in, attached). I have the slaves displaying =20
their left/right sides/eyes, but the render window on the master is a =20
small, empty window. I cannot seem to get the master to readback =20
(using the readback SPU) from the render nodes, as well as rendering =20
at a different resolution.

When I try the readback SPU, I get a small (not 1400x1024) window on =20
the slaves that flickers with the background, and the empty window on =20
the master. When I close the empty window on the master, the program =20
(using the city demo) then seems to run, but exits:

Thank you for using Chromium!

Is what happens after closing the empty window on master, when trying =20
to use the readback SPU.

Any help would be appreciated,

Thank you,
