Following example has about 7000 points dotted around the globe, it takes a noticeable performance hit after a couple thousand:

Example re-uses one Geometry, and ColorMaterial between all the points (CODE Below). Each ‘MarkerBase’ is in turn added to a ObjectContainer3D (app needs MouseOver/Out/Click handlers for the markers). Any help or pointers for optimizing whistle keeping functionality would be great.
Many thanks - Karim
