[OpenLayers-Dev] I am working on an Openlayers adapter to the Cesium

i really don't know how handy would that be, but keep in mind that as far as i understand a layer has a reference to one map, so if you want to have features drawn in the map and allow switching between openlayers and Cesium you must have two map, add features to both maps and have duplicates of all features and layers. But again not sure if this is true.

On the other hand, i didn't knew that Cesium could switch between 2D and 3D, so maybe that enough.
