3D Symbol Modeling Base On Direct3D API

With the fast development of information technology affects to the future military, more country want to build "digital battlefield".Using modern virtual reality of computer To build 3D maps is a important task in "digital battlefield". It is a qickly way use 2D maps which we had Digitaled to modeling 3D maps.After reference and analyze the article and document of domestic and international,Author make a research on 3D Symbol modeling by theory and practice, and write test progam use Microsoft?DirectX development Tools ; The main content are abstracted as follows:1) The character and meaning of the 3D Symbol. 3D Symbol is the product of the computer simulation technolog. It a accord with the transfer theory of map,rule of construct symbol .Use 3D transfer mapped objects because of It's looks like objects ,It's the most important character.2) Introduce Microsoft Direct3D API(Application Program Interface). Direct3D API is not use to write program of scientific calculate. We must say that compare with OpenGL, Direct3D API has an advantage of use now, although he has shortage of use past.3) Author analyze modeling 3D Scene form 2D map use theory and practice . Automatic modeling is the most difficult in 3D symbol designing, and it's import key of quckly modeling scene. Author statement the element of 3D symbol automatic modeling ,such as distribution of 3D objects.modeling 3D objects and effect on terrain.4) Designing 3D symbol modeling tool.Include the organize of 3D symbol and 3Dsymbol library ,of course some of edit operations are added.5) At last author analyze and experience the algorithms of 3D modeling tools.
