Abstract
Based on maximum value of distances between vertexes of polygons in plurality of polygon meshes, size of voxel is determined. Respective potential values for plurality of polygon meshes are obtained on basis of signed respective distances of voxels. Sum of potential values is obtained as added potential value. Polygon mesh made of equivalent face of added potential value is defined as surface mesh. Comparison between surface mesh and plurality of original polygon meshes is performed, to determine respective vertexes of plurality of original meshes corresponding to each vertex of surface mesh. Polygons of surface mesh are divided/synthesized to obtain intermediate surface data. Referring to original polygon meshes, respective vertexes of intermediate surface data are moved. Composed polygon mesh data are obtained with stability even if original three-dimensional data have errors, within practical time, without unnecessarily high redundancy, while maintaining accuracy and resolution of three-dimensional multi-viewpoints data.
