What do people build with it?

USE CASE 1

Generate a smooth sphere mesh for a 3D planet visualization without writing subdivision math by hand.

USE CASE 2

Create a skybox mesh for a browser-based game using an adjustable subdivision level.

USE CASE 3

Use the unit-sphere vertex positions directly as lighting normals for shading.

USE CASE 4

Build a data visualization that maps values onto the surface of a sphere.

What is it built with?

Copy-paste prompts

Prompt 1
Show me how to use icomesh to generate a sphere mesh with subdivision level 4 and render it in Three.js.
Prompt 2
Explain how icomesh's icosahedron subdivision works to produce smoother spheres at higher levels.
Prompt 3
Write code that uses icomesh's vertex output directly as lighting normals in a WebGL shader.
Prompt 4
How do I add texture coordinates to an icomesh-generated sphere to wrap an image around it?
