to translate the principle to 3ds max,
link to free tutorial.
after reading this about the nurbs sphere
Rendering wise: while a Polygon mesh is heavier than a NURBS mesh, it doesn't require tessellation while rendering, although more rendering time is required if you're using UV mapping.
A NURBS surface is made up of patches. During rendering, each patch is divided into an appropriate number of triangles to approximate the true shape of the surface. During render, if the mesh doesn't seem as smooth, running NURBS tessellation will add more triangles to smooth things up but will also require more rendering time.
Most of the time, NURBS are used for simpler objects, but it all comes down to using whichever you feel more comfortable with, modeling and rendering.
