Hi there,

I have a general question and this is to do with large quantities of 2D geometry.

Are there any general optimsation suggestions for large quantities of 2D Mixed Geometry using cesiumjs?

One thing I have noticed is that if the geometry (points, polylines and polygons) has any amount of transparency, it renders much faster in a scene.

Does anyone have anything further than this for optimising large datasets?
