3d performance glitchy

[HeavenlyHost]

So with reference to #477 and #465, the issue that we now have is within 3d runtime performance.

Reducing the number of point to around only 10 and updating at 10Hz the 3d Cesium map is glitchy on simple movement. Increasing either number of points or the frequency of updating of the GeoJSON data results in a below par user experience. The flickering is gone but panning the map resulting in jerky movements.

What is the best way to reload GeoJSON at 10-15Hz into the 3d view without causing this jerky-ness ???
