Hi all,
I am working on a simulator visualisation using OSG. This visualisation has some minor bugs producing an exception when loading a TEXTURED .obj File OUTSIDE the osgviewer's field of view. My problem seems to be a matter of thread-safety, because with osgviewer's threading model set to SingleThread, no problems appear. To the functionality of the visualisation, I derived an object from osg::MatrixTransform called VisObject and added some functionalities like an memorybuffer for the object data (pos, orient., scale, filename of 3d model, etc) as the information for the visualisation objects comes over Ethernet as a bytestream. The VisObject has one child, the object to be drawn e.g. an 3d model. The update of the position etc is handled by an update callback hooked on the rootnode. With untextured 3D models or basic primitives like boxes, everything works fine, the exception anly occurs while loading the textures in the moment, the 3d model comes into sight. The same VisObject, statically added to the scene unfortunately produces no problem :-( so the error must be in my concept. Is there anything to consider with reference to thread safety besides not changing the scenegraph during cull and draw traversals? Used OSG Version 2.4 Microsoft VS8 Windows XP SP2. Thanks for any advice or help, Tobias
