Here is a query I actually need to know the reply.

How is that :

Done in unity ?

I imply, after a bit of intensive analysis : ( instance of what I discovered )

https://www.researchgate.internet/determine/Spherical-grid-lines-of-latitude-and-longitude-Near-the-North-Pole-the-longitude-lines_fig4_23668865

I checked and succesfully managed to get a hexasphere working on a mission.

Checked the Catlike coding tuto on procedural meshes (https://catlikecoding.com/unity/tutorials/procedural-meshes/icosphere/)

Checked some gamedev math ( primarily trigo, angles and so forth … ) ( all of
Freya Holmér math serie for some math notions I used to be lacking :

And a whole lot of different locations & experiments .

From what I get up to now :
It look awfully like a latitude longitude mapping.
But how do you mission the grid on the sphere with out having to retailer every “sq.” in reminiscence ?
How do you handle to have diffèrent résolutions on the equator & the poles and every part in between ?

You can cleary see the place they made the totally different decision. particularly across the poles plus with a 4 quarters seperation of the sphere.

What i want to know if doable :

Where to seek out info / code to create one thing like that ?

How exhausting is it to implement ( on the mathematics aspect I imply ) ?

How do you place de constructing on the floor of the sphere to align with the grid relying on the place on it ( the maths behinds are tremendous, I can determine the remaining out on my own )

Any type of ressources that might assist me or clarify to me the way it’s performed is welcome !

That’s the details I want to know, i am going to experiment after and share a public mission for whoever need to do one thing like that later.

Thanks lots on your assist and your time !
