Having my starting problems with OpenGL and DRI fixed (thanks again @Ville) I'm now going for the 'real' project. We are developping an application displaying graphics and animations in realtime for scientific purpose. For programming these graphics on a high level we don't want to use something like DGA (in fact we have an old implementation using XFree86 DGA) but rather OpenGL (with DRI in order to achieve reliably high framerates). But we aren't going to use X because integrating a whole Xserver into RealtimeLinux would be a pain in the ass. Therefore we are looking for a leightweighted hardware abstraction library instead. I found the "DRI without X" page in the Wiki suggesting MiniGLX, DirectFB and FBDRI. FBDRI does currently work only on Radeon cards and seems to be quite dead. MiniGLX and especially DirectFB look quite promising and I'm going to have a closer look at both. However, there are a few points regarding to which I'd appreciate to hear your opinion: 1. Active development: Future hardware should be supported as well as possible. [I suppose this point is met especially by MiniGLX as they claim to be able to integrate new XFree86 drivers quite easily. Is that true? What about DirectFB?] 2. Running on a dual-headed graphics adapter: I don't know if this is possible at least in principle but it would be optimal if we could run X on one head and have this lean real-time graphics on the second
head at the same time. At the moment we have Matrox G550 cards. If this is not possible we would have to use two adapters in one system. 3. Vertical retrace signal: The program must be able to synchronize the graphics generation with the monitor frame rate as we need to know exactly the time each frame is displayed. [I saw there was a patch for DirectFB with mga?] 4. Lightweighted: We need a possibility to render graphics to the screen. This should be as easy as possible but need the mentioned requirements: reliably fast, timing control. We do not need anything else: No windowing, no user interaction (and therefore no keyboard/mouse support), no sound. Solely support for image loading and rendering could be useful, but this could be done by the application itself, too. Looking forward for any comments, ideas or hints Jan -- NEU FÜR ALLE - GMX MediaCenter - für Fotos, Musik, Dateien...
