Highest Resolution Wall Around

Posted by Hemos on from the anyone-for-home-use? dept.

akhaksho writes "NCSA (the National Center for Supercomputing Applications) is in the process of building the highest resolution display wall in academia. This is similar to the previous story about the wall at Sandia, but the intention of this wall is to get very high resolutions at a reasonable cost using off the shelf technology (for the most part). All of the code to run it and plans for the physical infrastructure will be available as part of the Display Wall in a Box effort. I'm one of the guys that built this sucker (and have the scars to prove it!) "

  1. Re:How do you sync the graphic cards? by akhaksho · · Score: 2, Informative

    We're using WireGL, which is a distributed OpenGL implementation out of Stanford. It has some code in it to synchronize the displays. Since we're using Myrinet (gigabit network with low latency), the pipes sync up pretty well. As for the stereo, we don't plan to do either. There are no projectors of this cost and form factor that are capable of active stereo and the complexity of mounting the projectors for passive stereo are too horrible to contemplate! :) We've got the other 20 projectors and plan to build another identical block next to the one we've already got.

    It is transparent to OpenGL apps. We're using WireGL out of Stanford which is a distributed OpenGL implementation.
