Abstract

A three-dimensional graph display apparatus is provided for dynamically changing a display format for a three-dimensional graph. In a simulator of a three-dimensional object shape model wherein a three-dimensional object shape model is comprised of two objects, i.e., an object which has data related to properties of a target three-dimensional object (referred to as the “model object”) and an object having data required to display the object (referred to as the “display object”); data of a plurality of model objects can be linked to one another; and the model object can be shared by a plurality of display objects, three-dimensional point data saved in a database is retrieved and the retrieved three-dimensional point data is converted to three-dimensional objects and an object (container object) having the three-dimensional objects representing the three-dimensional point data as slot values in its model object is provided.

Claims

1. In a three-dimensional model simulator wherein a three-dimensional shape model is comprised of two objects, that is, a model object having a plurality of slots for holding data related to properties of a target three-dimensional shape and a display object having data required to display the shape, a three-dimensional graph display apparatus comprising:

a point object having three-dimensional point data retrieved from a database as a slot value;

a container object having a plurality of point objects as slot values; and

a graph object for displaying a slot value of said container object.

2. A three-dimensional graph display apparatus according to claim 1, wherein one or more graph objects are linked to said container object by linking slots.

3. A three-dimensional graph display apparatus according to claim 1, wherein one or more graph objects share a model object of said container object.

4. A three-dimensional graph display apparatus according to claim 1, wherein said display apparatus is implemented on a computer system having a local file system and a database system, wherein said point objects are managed on said database system and said graph objects are managed on said file system.

5. A three-dimensional graph display apparatus according to claim 4, wherein said computer system is a distributed network computer system.
