Dear Ladies and Gentlemen,

I am currently working on developing a visualization tool using
OpenSceneGraph. I am supposed to develop a branch for the tool to work on
Android.

I am having some problems and my experience with OSG cannot really help me
pass it.



In few Words

-          -   My tool should have multiple views of the displayed object.
Something like CAD software or Maya (where you basically have 4 views, one
orthogonal view and 3 top, front and side views).

-         -    I easily managed to do that on Widows using Composite Viewer
displaying multiple Views.



On Android I used the example provided of GLES1. In the native code.
OsgViewer is used and it is setup in the window by using
*setUpViewerAsEmbeddedInWindow()
*.



-         -   I am trying to use different function to setup the view for
the windows but It does not seem to work, I am always getting this
error *(View::setUpViewAcrossAllScreens()
: Error, no WindowSystemInterface available, cannot create windows.*).

-          -  What do you think the problem here? for Android it is better
to use One *CompositeViewer* as the render object for the EGLView class in
Java? or is it better to make different EGL instances with different normal
*Viewer?*


Thanks in advance for your help,

Best Regards,

Mahmoud Aly
