Draw shapes on a sphere

Questions
1

Hi all!

I’m trying to build a sphere with shapes on it that I can click, hover, etc. Ideally I would be able to fill the entire surface of the sphere with shapes, like all faces for instance.

So far I have a sphere, lighting, etc. But for these different shapes I tried many things from the docs, but it feels like I’m missing something.

Are there any useful examples or some keywords that I’m missing?

Thanks a lot!

How about this?

Hi!
Would be cool to provide, at least, an explanatory picture of the desired result.
And even better, to provide an examle of what and how you do.

Thanks @hofk this is very helpful! Especially the “box on a sphere” example. Learned some new things already :slight_smile:

@prisoner849 You’re right. I could have been a bit more clear on what I mean. So I took some paper and a pencil to quickly sketch something down:

Does this make it a bit more clear?

Thanks!

From what I see on your picture, squares, that closer to poles of a sphere, will be smaller and more distorted, than the ones, that at the equator of the sphere.

Correct! The distortion is indeed related to the distance to pole/equator. I might decide to make some “taller” or “wider” to compensate for the size of the surface.
