quad_buffer cluster
I'm working with a networked cluster, 3 pc's with quadro gfx cards. They have frame synchronization in effect and my intention is to implement active stereo across all 3 screens. So far I have had mixed success.
I find the line: viz.go(viz.QUAD_BUFFER) will launch the cluster but active stereo is only enabled on the cluster master. On the other hand the line: viz.go(viz.ANAGLYPHIC) does in fact launch the entire cluster into anaglyphic stereo.. Just not quite what I'm after. Another approach I have tried is to enable stereo explicitly for each of the clients. Something like: viz.pushmask(viz.CLIENT1) viz.clusteroffset(-50, 0, 0) # yaw, pitch, roll viz.stereo(viz.QUAD_BUFFER) viz.popmask() #and repeat for each client viz.go() In this case it seems the statement viz.stereo is ignored. But again, this syntax works with other stereo modes like anaglyphic. Any info on how to get this working or about a limitation I've bumped into would be appreciated. The hardware should handle this and I'm keen to see it up on the projection system. Thanks, John. |

Thanks for the detailed description and troubleshooting. This sounds like you may have found a limitation but we'll verify this and get back to you tomorrow.

Looks like you found a bug. This will be fixed in Vizard 3. It is possible that there is a workaround and we will contact you directly.

Thanks, that would be great. I'm happy to provide some testing on this if you need it.
