[osg-users] Read frame buffer back into main memory

[Antoine Rennuit]

Hi all,

Hum, it seems my case is a bit more complex than expected. The camera I want to read the buffer from is a custom created camera:


Code:
    // Curvatures camera.
    m_curvaturesCamera = new osg::Camera();
    m_curvaturesCamera->setClearMask(GL_DEPTH_BUFFER_BIT); // The camera only clears the depth buffer before rendering (not the color buffer).
    m_curvaturesCamera->setRenderOrder(osg::Camera::PRE_RENDER);
    m_curvaturesCamera->setReferenceFrame(osg::Camera::RELATIVE_RF);




I have had a look at osg::Image, but it does not seem very clear which function to use and above all, how I shall indicate  to the osg::image which camera it needs to read from.

Any idea?

Thank you!

Cheers,

Antoine.[/code]
