ABSTRACT:
A figure retrieval method for storing memory addresses for figure data in an address data table which corresponds to positional coordinates of a multi-dimensional array. When retrieving end points, or node points, other points on a line and points on a surface, these points constituting the figure data, memory addresses for figure data for an object to be retrieved are stored in the address data table and then retrieved. Flags indicative of the kind of the constituent points are also stored in the address data table in combination with the memory addresses and are used for figure retrieval.
