摘要: PROBLEM TO BE SOLVED: To effectively search for a large quantity of information being searching object. SOLUTION: Each object SJ is included in hierarchical space SQ to form layer that defined as an n-th SLn. Then, the selected representative out those each plural divided blocks another upper (n-1)-th SL (n-1). The formation these layers are recurrently repeated virtually construct three-dimensional SS includes 1st layers. A picture obtained by viewing inside via point view PV having line sight reaching lower hierarchy from one displayed on screen. group retrieved moving SS. COPYRIGHT: (C)1997,JPO
