I’m trying to get some basic custom rendering working, but not having much luck. I want to be able to take a large collection of latitude/longitude pairs and quickly push these to the cesium display. I’ve used billboards to do this previously, which worked fine, however I’m also trying to offload as much out of main memory as possible. Billboards continue to consume main memory it appears. So I tried my hand at some customer rendering. My sample code is below, but nothing is appearing. I don’t believe I’m properly setting the position information, but not entirely certain how to do this, so would appreciate any pointers.
