| dc.description.abstract | Because the triangular mesh has characteristic which the form simple, is easy to process. And utilize triangular can form like any object, make triangular model in a lot of fields, including reverse engineering, medical skeleton model, rapid prototyping and so on, all have extensive application. However in view of the different demand, the quality of the triangular model all has the request of the certain degree, favor some following processing, like slicing, constructs surface and characteristic boundary picks up. So the wrong detection of triangular model is necessary, by the method, not only can understand wrong situation and solve but also can analysis the result of wrong triangular produced.
Have done the introduction to all possible wrong attitudes of triangular in this research, and put forward the proper solution. Moreover, divide into groups in the way to accelerate the speed that deal with of the triangular model. After finishing dealing with the mistake on the triangular format and links in relation, carry on the hole-filling finally. Make proper classification as to hole in a possible type, and obtain single and closed hole. Using the single-point type and multi-point type, the ways of two kinds of hole-filling are mended, in order to remedy the mutual deficiency each other. | en_US |
