PROBLEM TO BE SOLVED: To reduce the influence of noise and to prevent the overlap of polygons in a connection part by projecting the outline of a polygon mesh on the polygon mesh of a connection object in the direction of an average normal to make them correspond to each other and using the average normal. SOLUTION: The outline of the polygon mesh is projected on the polygon mesh of the connection object in the direction of the average normal to make them correspond to each other and the average normal is used. The polygon is previously divided along the outline of the polygon mesh and an unnecessary part is eliminated. In the device, and average normal calculation means 11 averages the normal vector of all the polygons. An unnecessary part elimination means 16 fills in a clearance generates as the result of the elimination of the polygon which becomes unnecessary by generating the new polygon in a new polygon generation means 17. A polygon mesh data integration means 18 makes data of the two polygon meshes into one data and completed a connection processing. |
