Share vector data and styles

[ahocevar]

Idea: Bring vector data the user interacts with in 2d into 3d, without having to load the data twice. Allow same styling, labels and tooltip information.

Cesium supported formats:

• GeoJSON, OK!
• KML is an ongoing work: https://github.com/AnalyticalGraphicsInc/cesium/tree/kml & KML Support CesiumGS/cesium#873
  Cesium examples:
• Styling
  • Points/Billboards: http://cesiumjs.org/Cesium/Apps/Sandcastle/index.html?src=Billboards.html&label=Showcases
  • Polylines: http://cesiumjs.org/Cesium/Apps/Sandcastle/index.html?src=Polylines.html&label=Showcases
  • Polygons: http://cesiumjs.org/Cesium/Apps/Sandcastle/index.html?src=Polygons.html&label=Showcases
  • Geometries: http://cesiumjs.org/Cesium/Apps/Sandcastle/index.html?src=Geometry%20and%20Appearances.html&label=Showcases
• Labels: http://cesiumjs.org/Cesium/Apps/Sandcastle/index.html?src=Labels.html&label=Showcases
  *Tooltips?

Notes

• Cesium places the 2D GeoJSON on the terrain according following rules:
  • Vertexes are precisely placed on the terrain
  • Segments go straight (in 3D) between the 2 Vertexes

The vectors.html example has been updated to show synchronization of a 3D polyline.
There is now a zigzagging line inside the square-like feature.
One of the two crossing lines has also be given an elevation.

Note that, as of version 1.1, Cesium has no support for drawing polygons with arbitrary elevation for their vertices.

The vector-related functions and synchronizer are now merged. So I'm closing this one.
