摘要
A new theory called default geometric reasoning is put forward, and the corresponding solid reconstruction algorithm is studied. The theory and the algorithms are further verified by a sample reconstitution.
The theory of default geometric reasoning (DGR) was presented and studied through solid reconstruction algorithm. The solid reconstitution hypothesis was given first in the process of DGR. The hypothesis was established on the basis of solid construction rules as simplification, DFM and DFA. A topologically correct solid was constructed with the aid of algorithm on solid closeness testing and supplementary faces. The calculation algorithm to get vertex, edge, loop and face was also studied.
