摘要： A quadrilateral or a hexahedron is used for a virtual object. If, for example, a quadrilateral mesh is composed of perfect squares and a voronoi diagram is dual to them, it is considered that the voronoi diagram comprises the perfect squares whose centers are connected to be a quadrilateral mesh. Accordingly, the quadrilateral mesh is generated by filling the object to be meshed with quadrilateral virtual objects corresponding to the voronoi diagram and connecting their centers.

摘要： A curved surface to be meshed and a tensor at each point on the curved surface are inputted. Then, bubbles are generated in parametric space corresponding to the curved surface and in accordance with tensors transformed according to the relationship between the curved surface and parametric space. Following this, the bubbles are moved in parametric space by inter-bubble force defined by a predetermined rule, and are transformed by using the transformed tensors. The number of the bubbles is also controlled, so that stable locations for the bubbles in parametric space can be determined. Next, a connection relationship between mesh nodes, which are centers of the bubbles located in parametric space, is determined in parametric space. Finally, a mesh is generated on the curved surface by employing the positions and the connection relationship of the mesh nodes.
