Okay, i have correct it by a second attachment from the camera colorbuffer to....the image already attached to the output rtt texture...:(
Code: _prerenderCamera[i]->attach(osg::Camera::BufferComponent(osg::Camera::COLOR_BUFFER), _RTTOutTexture->getImage()); I don't think it's nice ....I haved try a Code: osg::Image *im=outputtexture->getImage(); im->readPixels(0,0,im->s(),im->t(),GL_RGBA, GL_UNSIGNED_BYTE); in a osg::Camera::DrawCallback but it seems to fails: it read the mainview in the osg::Image and not the prerendertotexture results... Is there anyone who knows how to readback properly a osg::Texture2D in a osg::Image after a RTT pass? ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=24366#24366 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
