### How to create 3D mesh for Sphere

• Follow

```I'd like to create a rectangular mesh of a sphere, and a tetrahedral mesh sphere. how to do it?

I will use it for presentation.

Additional info: 3D regular mesh is used for Finite difference time domain computation, tetrahedra mesh is used for finite element method.

Thanks.

The only way to fit a rectangular mesh to a sphere would be to use
infinitely small rectangles -- unless, that is, you are willing to
specify a tolerance of uncovered area and indicate whether that is a
_total_ area uncovered or the acceptable uncovered gap at any one location.
