computation table
2.Summary table of proof of charge to an account presses accountant course collect, call course summary table again so, it rose to be record of concerned economy business before total classification Zhang, undertake trying calculating the effect of the balance beforehand, its are basic format and the structure that computation expresses evenly are identical.
3.This article proposes in order to quickly hidden processing is carried on to multi concavo-convex polyhedron, the hierarchical structure is applied to carried on description on TOPO relations of three dimensional physique; the bidirectional link table is applied to carried on the dynamic node assignment, for enhancing the efficiency of the algorithm; when multi three-dimensional body is being hidden processing, the screen projection polygon should be carried on the overlaped eliminating confirmation and the polygon edges be carried on the computation of the intersectant points, the depth inspection, the comprehensive test and so on.
