Fly view Manipulator

[nebsar]

Hello,
How can I override the 90 degree pitch up limit of earth manipulator? Or Is there a fly view manipulator in osgEarth?
Is there a way to render a custom screen image directly on the screen as 2D. For example in Java a custom buffered image can be directly rendered on the screen. I am trying to create the same HUD, which is attached ,I did on NASA WorldWind Java.

Thanks

One question per thread, please :)

You cannot override the pitch limit. OE only has the one EarthManipulator that is designed for GIS-style navigation. The correct solution is to implement a CameraManipulator for your application. OpenSceneGraph has several to choose from -- you can adapt one of those or write your own.

As for the HUD, refer to the "osghud" example in OpenSceneGraph for an example of an overlay camera.

Hope this helps.
