Hi, I want to make a screenshot of a osgShadow::ShadowScene. I have created an osg::Camera this way :
Code: camera->setClearColor(osg::Vec4(0.8f,0.8f,0.8f,1.0f)); camera->setClearMask(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); camera->setReferenceFrame(osg::Transform::ABSOLUTE_RF); camera->setProjectionMatrixAsPerspective(90,1.0,x,2*x); camera->setViewMatrixAsLookAt(_position, _lookAt, osg::Vec3f(0.0f,0.0f,1.0f) ); camera->setViewport(0,0, xres, yres); camera->setRenderOrder(osg::Camera::POST_RENDER); camera->setRenderTargetImplementation(osg::Camera::FRAME_BUFFER_OBJECT); camera->attach(osg::Camera::COLOR_BUFFER, myImage); camera->setFinalDrawCallback(new WriteCallback(filename, camera, myImage)); camera->addChild(_originalModel); [\code] If I make viewer.realize(); viewer.frame(); I will not see my 3D model. If I do viewer.frame() once more I will see my 3D model but no shadow on it. I know the problem is coming from the camera because if i create a viewer and run it with the same _originalModel before entering my screenshot procedure there is no problem. Someone could explain me the logic behind it ? I mean do I have to make a trick for having shadow on my screenshot. I have read about 2 cameras on another topic but not sure about. Thank you all :) Cheers, Benoît ------------------------ -- Benoît Bayol benoit.ba...@gmail.com ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=19891#19891 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
