Hi,
I understand that this problem has already been discussed . But as I was not
able
to understand clearly I post my simple camera rotation problem., I written a
code
osg::ref<osg::Camera> g_camera=new osg:::camera;
g_camera->setProjectionMatrix(osg::Matrix::ortho2D(0,1,0,1));
g_camera->setReferenceFrame(osg::Transform::ABSOLUTE_RF);
g_camera->setViewMatrix(osg::Matrix::Identity());
g_camera->setClearMask(GL_DEPTH_BUFFER_BIT);
g_camera->setRenderOrder(osg::camera::POST_RENDER);
g_camera->setAllowEventFocus(true);
g_camera->addChild(create_geometry()); //create_geometry() fn will return a
geode with //a drawable added
......
..........
.......
osgViewer::Viewer viewer;
viewer.setSceneData(g_camera.get());
.....
while(!viewer.done())
{
if(isKey_R_pressed){
....
......
osg::Matrixd vmat=g_camera->getViewMatrix(); //here i get the camera thru
traversal
vmat.makeRotate(osg::DegreesToRadians(45.),osg::osg::Vec3f(1.,0.,0.));
g_camera->setViewMatrix(vmat);
....
.....}
viewer.frame();
}
}
I dont understand how my geometry is not getting rotated?
Do you want to rotate the camera or the geometry you are looking at? The
camera with identity view matrix looks along -z axis, you are rotating
about x.
What is the problem in this?
I don't know what you want to do, so I cannot say. Try to explain what
you expect. What are you currently getting?

Thank you!
