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： The present invention provides methods, apparatus and systems to improve the quality of the arrangement of nodes in a graphics display, for which a graphics image consisting of nodes and arcs is generated, and to increase the processing speed. Nodes are sequentially added and arranged in a display space, and each time a new node is added, a predetermined dynamic model is employed to correct the locations of the new node and of nodes that were previously arranged in the display space. The nodes are arranged beginning with a node having numerous adjacent arcs, so that the nodes that are arranged early in the process are located nearer the center of the display space. In the graphics image thus formed in the display space, arcs located within a predetermined distance of a specific node are curved so they detour around the node.

摘要： A method is provided for generating a quadrilateral mesh and a hexahedral mesh. First, a geometric model, which is an object of meshing, is input. The model is either two-dimensional or three-dimensional. Multiple bubbles of a plurality of types are generated in a region of the geometric model. The bubbles are moved according to an interbubble force defined by a predetermined rule, and the bubble count is controlled to adjust a neighboring relationship between the bubbles, so that the stable allocation of the bubbles are determined. By connecting the centers of bubbles of a specific type, a mesh is generated.
