[osg-users] Play audio files

Hi, I am currently using SDLaudio for playing the sound of the videos I am using, but when trying to load 2 or more videos at the same time, it only plays one of them (and not always). I have read that SDL only allows one audio channel, so I think I have to start using something else. I want

Hi, great. OSG can maybe be more intelligent about these mappings, e.g. automatically creating a float texture, but I don't have time to look at it further. jp On 19/01/2012 11:30, wang shuiying wrote: Hi, J.P. Thank you very much, it works under your suggestion! Best regards Shuiying

[osg-users] osgautocapture not working

Hi all, I'd like to capture frames from an osg scene to create a video out of them. I'm using osgearth to build the scene. My plan was to modify the osgautocapture example, so that it can capture a sequence of images, instead of only a single image. However, osgautocapture does only captures an

Hi all, We have seen the same behavior as Anna in our immersive system. It has four screens; each screen has a single graphics context and either one or two cameras (depends on if running in mono or stereo). The system is driven by an Nvidia quadroplex containing four FX5800 cards, one card per
