I have implemented an RTT reflection in OSG, it's pretty straight
forward.
The code below may be of use to you.
camMatrix is set by viewer.getCamera()->getViewMatrix().
--- CODE ---
osg::Matrixd reflection( 1, 0, 0, 0,
0, 1, 0, 0,
0, 0, -1, 0,
0, 0, 0, 1 );
osg::ref_ptr<osg::Camera> camera = new osg::Camera;
camera.get()->setClearColor( p_clearColor );
camera.get()->setClearMask(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
camera.get()->setReferenceFrame( osg::Transform::RELATIVE_RF );
camera.get()->setProjectionMatrix( osg::Matrixd::identity() );
camera.get()->setViewMatrix( camMatrix * reflection );
camera.get()->setViewport(x, y, width, height );
camera.get()->setRenderOrder(osg::Camera::PRE_RENDER);
camera.get()->setRenderTargetImplementation(osg::Camera::FRAME_BUFFER_OB
JECT);
camera.get()->attach(osg::Camera::COLOR_BUFFER, p_texture);
--- CODE ---

Subject: [osg-users] RTT Camera for Reflections
Hi , I've also been dealing with the problem of RTT with osgCamera and
using it as reflections in my ocean. I'e used the reflection example as
a basis However The problem I have is I've been pulling the view matrix
from osgViewer and inverting it and using that matrix in my RTT Camera .
Needless to say I'm not getting the desired results. I was wondering if
anyone else has toyed with the same problem and if they might have any
advice for me in producing reflections in my scene.
