Generating quadrilateral mesh optimization and generated mesh re-optimization algorithm

Quadrilateral mesh optimization rules and computation method of quadrilateral quality factor are introduced, collisions detecting between edges is executed during mesh generation, optimization processing of intersect are realized, and simple and complex optimization algorithms of mesh generated are designed in the paper. The transformation relationship between the viewpoint coordinate and point coordinate in view frustum is inferred, and a method of determining optimization region based on the viewpoint is expounded, and applied in complex topology optimization of 5/3 structure. Mesh optimization algorithm is programmed and debugged. The algorithm realization processes are introduced in detail. It improved mesh quality and examples are shown to illustrate its feasibility.
