1. A solid shape describing method for describing a solid model in a 3-dimensional space, comprising the steps of:
defining a fixed coordinate system with respect to said 3-dimensional space;
defining a single or plurality of floating coordinate systems;
describing a relative positional relationship algebraically between each respective floating coordinate system and said fixed
coordinate system;
defining a single or plurality of three-dimensional cell arrays; and
describing correspondence between a respective floating coordinate system and each respective three-dimensional cell array.
