Hi, I'm trying to use mutlipass rendering with osg, I would like to render my 3d scene in a texture and use this texture in some fragment shader for post-processing (I'm working for GL ES2).
That's my first time with OSG, there's a lot of obscure things for me, so be clement please :) 1 - I've just created a RTT camera inspired from osgprerender (so RTT cam is part of scene graph) I have now my 3d scene rendered on a plane ! Cool ! My first problem is that I'm using a camera manipulator (trackball), and this manipulator is attached to the main camera so I manipulate the plane with the texture instead of my 3d scene ... :( I would like to attach the manipulator to my RTT camera, and the main camera should just be a static ortho cam !! I've seen this post : Attach camera manipulator to RTT camera instead of viewer? (cannot paste the link cause it's my first post ... :? ) which describe exactly the same problem, I understand that I can only attach the manipulator to the main camera or to it's slave (using setAllowEventFocus), not on cameras added to scene graph. But I have no idea on how to use slave camera for rendering to texture ? All provided exemples I have seen use the same method that I used .... Could you enlighten me about this point ? 2 - Another thing I was wondering is how can I order my RTT cameras if I have more than one ? Using camera->setRenderOrder(osg::Camera::PRE_RENDER); doesn't allow me to specify which RTT camera should be render in first place ? Thank you!
