Icosphere by recursive subdivision
In your harnessMesh algorithmMIT
Build an evenly tessellated sphere by splitting a regular icosahedron into four triangles per face and projecting onto the sphere. Use it for physics bodies, planets and smooth balls.
What it takes and gives
- Entry points
- icosahedron, icosphere, main
- Parameters
- radius, subdivisions
- Complexity
- O(20 * 4^subdivisions)
- Axes
- +Y up, metres
Limits. No texture coordinates: an icosphere has no seam-free UV layout; add a spherical projection if needed. Triangles are close to equal but not identical in size (edge lengths vary by about 20 percent at three levels). The polygon volume is below the true sphere's.
