the earth is not round and it looks rough and how to implement timeline like in cesium

[liuronghui]

Thanks for your great work. What I want to ask is that the earth is not round and it looks rough. How to draw a more fine ball? Another question is timeline in cesium. How do I implement it in your webglearth? Thank you

I want to create the earth with the same design as the following. Now I've finished the popup label, but the earth is not so round, and it's like the timeline effect in Cesium. I don't know how to do it in your project.
