Abstract
Grid structured data arranged for a spherical structured grid constituted by combining two component structured grids are visualized by using computer graphics technology. Coordinate conversion means 31 converts grid point coordinates of first and second component structured grids (referred to as N and E systems, respectively), represented by specific regions in spherical coordinates, into local xyz coordinates used in computer graphics. Filter means 32 obtains first and second graphic objects for the N and E systems, respectively. Using E system rotation and N and E system synthesis means 33, the second graphic object for the E system is rotated by 90 degrees with respect to an x axis of a first local xyz coordinate system, and is then rotated by 180 degrees with respect to a z axis of the first local xyz coordinate system, thereby obtaining the rotated second graphic object for the E system, and then, both of the graphic objects are synthesized.
