X3D Scenes in cartesian and geospatial coordinates

[sirtobi79]

The (Ala Moana Hawaii) test scene from VR Forces is used to provide a test example for DIS to X3D interpolators. The goal is to show both Cartesian and geospatial coordinates.

Cartesian:

• Y is up, 0 is ground,X north, Y east, Z west
• Use an image ruler to estimate waypoint values
• PositionInterpolator, OrientationInterpolator and WaypointInterpolator
• IndexedFaceSet for image texture on ground plane
• TODO: convert DIS geospatial PDUs to local x y z
• Provide JavaClass with Converter

Geospatial:

• DIS coordinate system
• Corresponding X3D geospatial reference frame (choose one)
• GeoTransform for image quadrilateral
• GeoPositionInterpolator for line-fit PDU values

These utility methods will be further checked as part of distilling X3D interpolator stream outputs.
