Discriminatory analysis for algebraic surfaces of more than second order

摘要

This article represents some first results of the work of finding the methods for getting presentation of real world complicated surfaces (objects of the real world) with the algebraic surfaces. It incorporates: 1. Finding base elements (base surfaces) which will be put to the structured library. 2. Studying regularities in shape changing and coefficients changing. Here are some reasons and results of adding the fourth variable to the surface equation.
