Based On Multigen Creator Terrain Modeling Study

The three-dimensional landform emulation technology is that the suppositional real technology is hit by a most important technology field, That suppositional real hits the target building a model is that computer graphics is hit by one of the most popular direction at present , is bringing the important effect into play and in all professions and trades,if the building , military affairs , entertainment.The main body of a book with Ministry of Education's "chunhui plan" as background, Build model platform combining with MultiGen Creator software landform, Have studied three-dimensional landform relevance technology and landform modeling method , have suggested that a set of effective 3-D landform generates the fairly good three-dimensional landform having applied a scheme,having built optesthesia effect successfully. That three-dimensional landform builds a model is one basis job. The main body of a book has been carried out from the three aspect such as simplifying and accelerating founding relevance technology , modeling method , three-dimensional landform model needed by model studying , has got certain achievement. Research done by I has these the following content;That right away, Creator landform structure builds , the DED document generates an implement, as well as in Creator is how to come to organize the data base document, how the supported by Creator figure elevation form is DED form , vein , characteristic mapping how, to establish LOD landform , apply a landform realize way in gaining a technology in three-dimensional landform data. The type having discussed that landform changes the method design , establishes landform LOD , the landform characteristic mapping and sets up projection has done priority among them expound. After being in progress to the Delaunay triangle net and the part Delaunay triangle net generating algorithm studying, If sampling wave filtering law is in progress melt letter, Facilitate an algorithm owing to deleting the net lattice handling. Have studied fundamental two fork tree thought and have built build, Be in progress in four fork tree data organization-based simplification from three aspect studying, one is fundamental thought, two is that DEM is hit by four fork tree structure process , three are rift phenomenon and the reparation to the rift, and study to being that Delaunay triangle net generating algorithm is in progress owing to that triangle net detail arrangement of ideas facilitates an algorithm.
