ABSTRACT:
In a search method and system for reducing the number of memory page-in/page-out operations to display, three dimensional objects are extracted through space search. The system comprises a parameter accepting module (22) which accepts parameters from a user to set up a view volume, a space searching module 24 which searches for an object which is included in the view volume, a tree holding module (28) which holds a multi-dimensional tree describing the three-dimensional coordinates of the object, and a file reading module (29) which loads the object data into memory in file units.
