Can we remove the earth?

Hello everyone,
with a colleague of mine we want to draw a global time space with cones to make it simple, with top of cone at exact location of cities and the cone should extend below (so below ground). This is relevant from my geographical perspective, and I do not want to draw these cones “in the air”. My issue is the following: is it possible to remove the earth from the scene?
This would be a development of this representation:

Thanks for help

Hello Alain,

Wow, this sounds like a really interesting project! I would love to see how it turns out.

It is really easy to turn off the globe. Here’s a code sample:

var viewer = new Cesium.Viewer(‘cesiumContainer’, {
globe: false,
skyAtmosphere: false




Great, it works, which means Cesium is the right platform for my project, thanks Hannah.
Will make some publicity on it as soon as something showable (is it english?) comes out.
so thanks also for the encouraging words!

Sounds great! We love featuring projects on our website, so if you’re interested we can see about putting together a showcase once you have something working =)
