Abstract:
1. A method of storing substantial data integrating shape and physical properties, comprising the following steps: an external data input step (A) for inputting external data consisting of boundary data of an object; an Octree division step (B) for dividing, by modified Octree division, the external data into cubical divided cells with boundary surfaces orthogonal to each other, wherein each divided cell is classified as only one member of the group consisting of (1) a non-boundary cell not including a boundary surface of the object and located in the interior or in the outside region of the object, and (2) a boundary cell including the boundary surface of the object, wherein the modified Octree division comprises the steps of: a cell data storage step (C) for storing the values of physical properties for each of the cells.
