Tilting Globe no longer possible

[lucgirardin]

Description

Up to at least version 2.0.0-986, it was possible to tilt the plane in Flat mode. This is no longer possible with the latest version of WorldWindJava.

Expected behavior:
The view should tilt and provide some kind of 2.5D view.

Actual behavior:
No effect.

Steps to Reproduce

1. Run the demo
2. Switch to Globe -> Flat
3. Try to tilt using Shift-Mouse-Up/Down or using the buttons

Reproduces how often:
Always

Operating System and Version

Windows, macOS, and Linux using version 2.2.0

Additional Information

There was a similar report posted in the WorldWind Forum:
https://forum.worldwindcentral.com/forum/world-wind-java-forums/development-help/156698-world-wind-java-2-1-0-earthflat-no-longer-allows-tilt

I am happy to investigate more, but it would be very useful to get any information on what may have triggered this change of behavior, i.e. was this intentional, a side effect of a change, or a raw bug?

Hi @lucgirardin. It might have been a bug that slipped in that broke the flat-mode tilting. You could check what commits occurred after version 2.0.0-986 that are related to EarthFlat and BasicOrbitView. Maybe BasicOrbitView doesn't work properly and some changes from the now-deprecated FlatOrbitView should be incorporated into BasicOrbitView to allow the flat-mode tilting to work with EarthFlat.

Fixed in PR #52.
