%X An algorithm for generating 3D surface of functions defined implicitly by algebraic equations is given. Tetrahedron division of the space is used in the algorithm. The approximate surface of functions is formed by pieces which are obtained from each of the tetrahedrons. This algorithm is relatively ease to implement and very practical. The algorithm can also be used to generating contour surface from algebraic equations, or from a set of numerical data related to points in space.
