nobody an idea? i tried another thing, but there is no sceneobject on the image ive also tried the osgscreencapture example is there a way to get rid of the callback? i need only one screenshot
Code: void render() { osgUtil::SceneView *SceneView = new osgUtil::SceneView; SceneView->setDefaults(); osg::ref_ptr<osg::Node> pNode = osgDB::readNodeFile( "C:/cessna.osg" ); SceneView->setSceneData( pNode ); osg::ref_ptr<osg::Camera> pCameraNode = new osg::Camera; const osg::BoundingSphere& bs = pNode->getBound(); int r = bs.radius(); pCameraNode->setProjectionMatrixAsOrtho2D( -r, r, -r, r ); pCameraNode->setViewMatrixAsLookAt( osg::Vec3( r*100,-r*100, r*100 ) , osg::Vec3(bs.center()[0], bs.center()[1], bs.center()[2] ),osg::Vec3(0.0f,0.0f,1.0f)); osg::ref_ptr<osg::Image> pImage = new osg::Image; const osg::Viewport* Viewport = SceneView->getViewport(); int Width = 1024; int Height = 768; pImage->allocateImage(Width, Height, 1, GL_RGB, GL_UNSIGNED_BYTE); pCameraNode->setClearColor(SceneView->getClearColor()); pCameraNode->setViewport(0, 0, Width, Height); //pCameraNode->setRenderOrder(osg::Camera::POST_RENDER); pCameraNode->setRenderOrder(osg::Camera::PRE_RENDER); pCameraNode->setRenderTargetImplementation(osg::Camera::FRAME_BUFFER_OBJECT, osg::Camera::FRAME_BUFFER); //pCameraNode->setRenderTargetImplementation( osg::CameraNode::PIXEL_BUFFER ); pCameraNode->setComputeNearFarMode(osg::Camera::DO_NOT_COMPUTE_NEAR_FAR); pCameraNode->setReferenceFrame(osg::Camera::ABSOLUTE_RF); pCameraNode->setProjectionMatrix(SceneView->getProjectionMatrix()); pCameraNode->setViewMatrix(SceneView->getViewMatrix()); pCameraNode->attach( osg::Camera::COLOR_BUFFER, pImage.get()); pCameraNode->addChild(pNode); SceneView->setSceneData(pCameraNode.get()); SceneView->update(); SceneView->cull(); SceneView->draw(); osgDB::writeImageFile(*pImage, "c:/tools/test.png"); } ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=38527#38527 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
