Hello,
I modified slightly the osgviewer application to add the following hierarchy
on top of the loaded model to allow model and post-process shaders to be applied.
Here is what it looks like:
// root
// \
// post-processing effect (see post-shaded root below)
// / \
// ... model effect
// \
// loaded model
//
//
// post-shaded root
// / | ... \
// perspective cam ortho cam 1 ortho cam n
// | | |
// model effect quad 1 ... quad n
Now when I did that I lost the viewer default trackball manipulation and the
'w' wireframe mode.
Two questions:
1. What would be the way to restore the wireframe default mode ?
2. To restore the trackball I did something like:
osg::ref_ptr<osgProducer::KeyboardMouseCallback> kbmcb = viewer.getKeyboardMouseCallback();
osg::ref_ptr<Producer::Trackball> trackball = new Producer::Trackball();
trackball->input( kbmcb->mx(), kbmcb->my(), kbmcb->mbutton() );
osg::CameraNode* pMainCam = const_cast<osg::CameraNode*>(pDemoEffects->GetCurrentPostEffect()->GetSceneCamera());
if(pMainCam != NULL)
pMainCam->setViewMatrix(osg::Matrixd(trackball->getMatrix().ptr()));
Now this works but the lighting is affected... How can I restore the default behavior ?
Thanks a lot in advance for your suggestions !
guillaume
