Does it work in debug? If it does not debug should give you much more info to track why you
Does the scene load in osgviewer.exe ? A couple of reasonable guesses would be that * you're possible mixing release/debug libs/dlls * or you're mixing libs/dlls built with different compiler versions VS2005/VS2008 etc * or you're mixing versions of lib's/dll's that have different patch levels Gordon Tomlinson Product Manager 3d Technology & Project Wyvern Overwatch(r) An Operating Unit of Textron Systems -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Inos Tranac Sent: Friday, May 21, 2010 8:45 AM To: [email protected] Subject: [osg-users] Access violation in osg61-osg.dll? Hello everyone, I have a really frustrating situation on my hands here. I've made a simple application that loads a scene and then does something with it. When I try to load certain scenes, my program crashes occasionally(!) in release mode and gives me this error: Code: Unhandled exception at 0x72e39083 in Diploma.exe: 0xC0000005: Access violation reading location 0x02f0b154. Other times everything seems to be working perfectly. The address of the exception seems to be pointing to osg61-osg.dll The call stack looks like this: Code: > osg61-osg.dll!72e39083() [Frames below may be incorrect and/or missing, no symbols loaded for osg61-osg.dll] osg61-osg.dll!72e4678d() osg61-osg.dll!72eac7c3() osg61-osg.dll!72e8d23d() osg61-osgUtil.dll!6ecde669() osg61-osgUtil.dll!6ecdeaab() osg61-osg.dll!72e70358() osg61-osg.dll!72ebf7ff() osg61-osgUtil.dll!6ecdea4d() osg61-osg.dll!72e4e938() osg61-osg.dll!72ebf7ff() osg61-osg.dll!72f1a14e() osg61-osgUtil.dll!6ecdea4d() osg61-osg.dll!72e7f198() osg61-osg.dll!72ebf7ff() osg61-osgUtil.dll!6ecdea4d() osg61-osg.dll!72e4e9b8() osg61-osg.dll!72ebf7ff() osg61-osgUtil.dll!6ecdea4d() osg61-osg.dll!72e4e938() osg61-osg.dll!72ebf7ff() osg61-osgUtil.dll!6ecdea4d() osg61-osg.dll!72e4e938() osg61-osgViewer.dll!6ec4e473() osg61-osgUtil.dll!6ed2d0b4() osg61-osgViewer.dll!6ec500f7() msvcp90.dll!74124f2a() osg61-osg.dll!72ebf10a() ot11-OpenThreads.dll!75742098() msvcr90.dll!741d3433() msvcr90.dll!741d34c7() kernel32.dll!760c3677() ntdll.dll!77d09d72() ntdll.dll!77d09d45() Now, I've read all about Heisenbugs and differences between Debug and Release modes, so I know it's my fault, but if you look at the code, the program doesn't crash until the last line, when there's a call to viewer->run(): Code: root = new osg::Group; viewer = new osgViewer::Viewer(arguments); //the non-colored scene that will be shown before and after the algorithm sceneNoColor = osgDB::readNodeFiles(arguments); TextureRemover *textureRemover = new TextureRemover; osgDB::Registry::instance()->setReadFileCallback(textureRemover); // read the scene from the list of file specified commandline args. scene = osgDB::readNodeFiles(arguments); if (!scene || !sceneNoColor) { osg::notify(osg::NOTICE)<<"No model loaded"<<std::endl; exit(1); } osg::ref_ptr<PrimitiveCountVisitor> primitiveCountVisitor = new PrimitiveCountVisitor; scene->accept((*primitiveCountVisitor)); long numPrimitives = primitiveCountVisitor->getNumPrimitives(); postDrawCallback = new SnapImage("PostDrawCallback.png", numPrimitives, osg::Vec4(1.f, 1.f, 1.f, 1.f)); scene->setDataVariance(osg::Object::DYNAMIC); osg::ref_ptr<GeometryPaintVisitor> paintVisitor = new GeometryPaintVisitor(numPrimitives); scene->accept((*paintVisitor)); osg::ref_ptr<osg::Switch> mainSwitch = new osg::Switch; mainSwitch->addChild(sceneNoColor); mainSwitch->addChild(scene); mainSwitch->setSingleChildOn(0); mainSwitch->setName("ij_MainSwitch"); osg::ref_ptr<osg::MatrixTransform> mt = new osg::MatrixTransform; osg::Matrix m; osg::Vec3f boundingSphereCenter = scene->getBound().center(); m.setTrans( -boundingSphereCenter.x(), -boundingSphereCenter.y(), -boundingSphereCenter.z() ); mt->setMatrix( m ); if (mainSwitch.valid()) { mt->addChild(mainSwitch.get()); root->addChild(mt.get()); } //compute the center point and the radius of the bounding sphere osg::BoundingSphere boundingSphere = mt->getBound(); boundingSphereRadius = boundingSphere.radius(); boundingSphereCenter = boundingSphere.center(); viewer->getCamera()->setPostDrawCallback(postDrawCallback.get()); osg::ref_ptr<osg::Group> newRoot = new osg::Group; newRoot->addChild(root.get()); newRoot->setName("rootNode"); // add the HUD subgraph. newRoot->addChild(createHUD().get()); root = newRoot.get(); // set the scene to render viewer->setSceneData(root.get()); viewer->getCamera()->setClearColor(osg::Vec4f(1.f, 1.f, 1.f, 1.f)); return viewer->run(); I guess I'm corrupting some memory, which the viewer->run() then uses, but I can't find what I'm doing wrong because the debugger won't let me into the run() method. The program crashes before showing the scene on the screen. Does anyone know how to tackle this problem? Thank you in advance.
