Re: [osg-users] Disabling HUD in one camera

[Robert Osfield]

Hi Mike,

If you use a Camera in the scene graph then it'll appear once for each
viewer Camera that encloses, unless you use traversal/node masks to
cull it.

The better solution is to do the HUD in a slave Camera within
osgViewer::Viewer, or a separate View in a CompositeViewer, as then
you can explictly bind the Camera to a particular GraphicsWindow.  See
the osghud example in 2.x.

Robert.

Hello

I currently have a setup with one viewer with two cameras. I add a HUD 
to the scene (as a child to the root node) and it shows up in both 
camera views. Is there an easy way to disable seeing it in one view? 
Some camera-Set... that will do this? (based on depth or something?)


osg::Camera is a subclass of osg::Group, and the scene data is just a 
child of the camera. If you do camera-addChild(hudCamera);, then the 
HUD will only show up on that camera (since the HUD is not below the 
scene root, which is a child of all cameras).


Hope this helps,

J-S
