Triangulation Of The Three-dimension Object In The Space

As the technology development of the space triangulation meshes which accelerate the procedure of the digital produces.It can widly applicated in various of fields,such as CAD,CAM,Reverse Engineering,Geography Information System,Three Dimensional Animation, Virsual Reality,Augmented Reality and so on ,that because it can build up the object module with some characteristics ,such as the convenient,accurate,swift and efficient.Therefore,it play a vital importment role in such fields as industry produces,social entertainment,economic development,modern military and visual medcine ,and get a manifest achivement.because there are still exist several problems in the splited triangunation mesh ,which need some improvement,and in the next five chpters the detail procudure will be introduced .In Chapter 1,we mainly introduced the background of our work. We classified the split triangunation meshes methods reasonably; earlier models of the trinagunation mesh and the latest developments in this field were discussed detailed. We bring out our train of thought based on the accomplishments of these issues on recent years.In Chapter 2 introduced the detail method about the LOD split triangunation meshes(STM) . We researched the LOD triangunation meshes simplify method which baseed on the timely and interactively feature. Base on the third dimension requirement ,we put on weight to research the dynamic LOD trinagunation mesh ,according to the diversion between the import degree and the visual analysis degree.In Chapter 3,base on the 3D scatter space point,we get the space curve face division method through the improvement of the STM, and researched the boundary circle in form of the splited,fuse and closed.The interface-line method introduced under the non-hole module data,and verified the algorithm is availability and veracity.In Chapter 4 As the evenly result and the visual efficiently of the integrity object,we introduced the optimation method to the STM when it was builed up,and put on weight researched on the thchnology of the whole optimation and the module subdivision optimation.In Chapter 5 is the conclusions of the whole thesis, we given out the still exist problem in STM,and introduced the work need to improve and hard study in the future.
