Research Abstract

A three dimensional geometric modelling system is developed as a fundamental study. One is a development of a solid modelling system which represents any kind of objects. This system generates an object with polyhedron representation. The system have many functions which are generation of objects, set operations called union, subtraction, intersection, display of hidden line elinination, display with shading, and so on. The other is a development of geometrical modelling system of free-formed surfaces. In the future, a three dimensional geometrical data-base with an intrlligent interface can be realized which have geomentrical analysis, geometrical sort, geometrical comparison, and so on.
