X3D Scenes in cartesian and geospatial coordinates #2

Open sirtobi79 opened 4 years ago

sirtobi79 commented 4 years ago

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.
