WolframLang: Mesh Region

Mesh

Mesh is a efficient data structure that represent a surface, solid, or region, by triangles (aka simplexes). e.g. 3D wireframe models.

For example, a line is given by 2 end points. But you might need to apply a transformation function to deform it. You need to break the line into tiny segments so the function can be applied to the points on the line.

another example, Sphere represent a sphere of a given center and radius, but often you want to represent it as mesh of triangles, so that you can operate on the surface.
