How can I calculate the UVs of a triangular mesh?
Hello,
I'm currently working on a sphere world, built subdividing an icosahedron, in which every triangle is a mesh. Now, I've got the vertex, triangles and normals generation working perfectly, but I can't understand how to calculate the UVs of said triangles.
How could I proceed? I know there's a way to calculate the UVs of the whole icosphere, but i just need to do it for triangular meshes that are floating in a 3D space.
Thank you in advance!
You might consider using Triplanar Texturing to set the UV coordinates.
There is a description here (See Example 1-3):

This is exactly what I needed! Thank you very much!
I'd like to add another resource i found while reading yours: an advanced tutorial on catlikecoding (the others in this series are pretty amazing too) https://catlikecoding.com/unity/tutorials/advanced-rendering/triplanar-mapping/
