20k entities limit for Cesium performance

Hi,

I heard from a friend attending Siggraph last year that Cesium render engine can compromise when dealing with >20k entities. Is it still true now? Any work-around if so? Thanks a lot.

Hi,

If you’d like to render lots of points take a look at this blog post which covers just that.

Hi Tom,

Thanks a lot. PointPrimitive is awesome! But one problem though, I render tons of tracks and each track has s symbol image. Right now I use billboard which allows me for that. I don’t see PointPrimitive can take a image. Is that true? Am I missing something? Thanks again.

You are correct. PointPrimitive is tailored for only the use of points (making it faster) and you can’t add an image. For this you must use Billboards like you’ve said.
