I came across this board and it’s inline with what I am trying to do, which is, to investigate which performs better, Entity or Primitive. Basically, I am optimizing my page that loads thousands of Entities (5 thousands - 7 thousands) where each entity contains a PointGraphics and ModelGraphics and these 2 are toggled depending on the Camera’s height relative to the surface of the earth. I am currently using the Entity API system (latest version of Cesium) and surprisingly Cesium can take it. I am wondering if using the primitive (model), would it give me better performance? I am guessing NO, because in theory Primitive (model) has overhead since it’s lower level compared to the Entity counterpart.
What do you think?
Also, it would be nice if Cesium supports sharing the Geometry info/data of a certain Model across entities. Meaning, if I have 1000 entities pointing to just 1 instance of a ModelGraphics. I think in theory this would give better performance and memory consumption.
