public class Mesh extends Geometry implements Iterable<int[]>, IMeshConvertible

A mesh is made of many n-sided polygons. Example: To add a polygon in mesh:

Mesh mesh = new Mesh();
  int[] indices = new int[] {0, 1, 2};
  mesh.createPolygon(indices);

Travel through all polygons in mesh:

Mesh mesh = new Mesh();
  for(int[] polygon : mesh)
  {
      //deal with polygon
  }
