Sphere and Plane are the most common surfaces. Sphere is a surface of genus 0. It has a constant Gaussian curvature of 1. It is a surface such that every point on the surface is equal-distant to particular point C. Sphere is the 3-dimentional analogous of a circle.

Algebraic formula: x^2+y^2+z^2==r^2, where r is radius.

Parametric formula: {Cos[t]*Cos[u], Sin[t]*Cos[u], Sin[u]}, where t goes from 0 to Pi, and u from 0 to 2*Pi.
