I know someone I work with had a go at Equalizer, but we ended up choosing Chromium for precisely the reason you mention, Chromium does not require you to modify the applications. From: Chang Yuan [mailto:[email protected]] Sent: Thursday, December 11, 2008 1:39 PM To: Brock Palen Cc: Andrew Shewmaker; [email protected] Subject: Re: [Chromium-users] Modern Chromium Hi all, Here are my two cents. SAGE is great for image/video applications, but may not be the best choice for distributed graphics rendering. It handles OpenGL applications by intercepting glSwapBuffer call and then streaming the buffer content (instead of OpenGL calls) to the display tiles. The images are rendered with inevitable upscaling artifacts which are quite visible on the display tiles. It does allow running unmodified OpenGL applications, though. For my own application, I am using the OGRE rendering engine (http://www.ogre3d.org), which uses some advanced shader programs (possibly >OpenGL 1.5). I tried to connect it with Chromium, but the scene is rendered with missing content (due to the lost shaders I guess) with a very low frame rate. Has everybody have successful experience with running OGRE through Chromium? Right now I'm sending the pixel buffers through SAGE as a backup solution. I plan to try another distributed rendering engine, Equalizer (http://www.equalizergraphics.com/), that claims to support all versions of OpenGL calls. But it requires modifying the program, which could be a turn-off for some people.
