Hi Arfaa,
here is my implementation:

Code:
bool ViewerWidget::setMainCameraFieldOfView(double iFov)
{
   osg::Camera* camera = mainView()->getCamera();
   double fovy, aspectRatio, zNear, zFar;
   bool result = camera->getProjectionMatrixAsPerspective(fovy, aspectRatio, 
zNear, zFar);
   if (true == result) {
  camera->setProjectionMatrixAsPerspective(iFov, aspectRatio, zNear, zFar);
   }
   return result;
}



ViewerWidget inherits from osgViewer::CompositeViewer. Anyway what I notice on 
your code is that you use a CameraViewer while I set the FOV to a osg::Camera. 
You could try the code on a osg::Camera and if it works then I guess there is 
something to investigate on the CameraViewer side.

HTH, Gianni

Hi,


Code:
double fovy, aspectRatio, zNear, zFar;
_camera->getProjectionMatrix().getPerspective(fovy, 
aspectRatio, zNear, zFar);

double aspect = (double)scrw / (double)scrh;
_camera->getProjectionMatrix().makePerspective(45, 
aspect, zNear, zFar);



Thank you!

Cheers,
Johny
