Hi Alexandre, hmm, one of the main change between 0.2 and 0.3 was a deprecation of Shader class. When you use them you will get a warning that they are deprecated and ShaderAttribute has to be used. Maybe there are some print outs, which slowdone your machine. Also I have tried to solve some multithreading issues. You could try to run your application in SingleThreading mode to make sure that your problems are not multithreading related. Even if you think you use only single threading, that might not be the case. Per default osgViewer does run in CullDrawThreadPerContext which isn't stable on older version of osgPPU. You should run it in SingleThreaded to force real single threading mode.
Also start your app with OSG_NOTIFY_LEVEL=debug or info and check whats going wrong there. Maybe post the output here, so that we could try to find out, whats going on. As to the getOrCreateOutputTexture(0) : the method should give you a correct pointer to a 2D texture (v0.2) even if your ppu isn't connected anywhere. The method also doesn't changes a lot to v0.3, hence I am not sure why it doesn't work for you. Maybe a problem somewhere else? If you are not restricted to use osg 2.6 you can try the current osgPPU from the svn, which has no multithreading issues anymore (as far as I was able to test it ;) ). However you need osg somewhere from 2.7.8 or so, to be able to compile current osgPPU :( Best regards, art ------------------ Read this topic online here: http://osgforum.tevs.eu/viewtopic.php?p=4671#4671 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
