Hi, I've got an OSG application with a single viewer and camera. The camera is set to render to FBO -
Code: camera->attach(osg::Camera::COLOR_BUFFER0, m_texture2D); camera->setRenderTargetImplementation(osg::Camera::FRAME_BUFFER_OBJECT); Rendering consists of the following main steps: 1) Render scene 2) Post-processing using osgPPU 3) In final draw callback, copy the rendered image to the application using two alternating PBOs Now I'd like to add one more step - 1.5) Copy the rendered image to application before post-processing The copied image will only be used in the application (e.g. to save it), and will not be displayed nor copied back to the graphics card (like the osgprerender example). In addition, I don't mind getting it with a delay of a few frames. How would you recommend implementing this step efficiently, while maintaining the current performance level of the application (runs at 60Hz). I guess I could use two separate cameras to render the scene (one without osgPPU), but I wonder if there is a better way.
