Tree-dimensional Modeling Based On DirectX

The world that we live in is a three-dimensional world, all the objects that we can see arethree-dimensional, even if a two-dimensional picture, the media that it was attached is alsothree-dimensional. The study of objects is actually study of these objects’ three-dimensionalmodel. In the past, three-dimensional modeling techniques have not appeared when peoplestudy real objects only through the many two-dimensional picture of an object from differentangles to simulate the three-dimensional structure or plaster model to reproduce it, thismethod is bad efficiency and low accuracy. In modern times, with the rapid development ofcomputer technology and image acquisition technology continues to progress, thethree-dimensional modeling approach is becoming the primary means for people to study thethree-dimensional world. Among them, the well-known three-dimensional human body slicetakes the medical profession on a human studies into a new level, the basis of this technologyis built above the three-dimensional modeling, not only that, the tedious hand-painted drawingof the works of the past gradually replaced by the computer3D graphics, which makesindustrial processes more smoothly. In public life, the three-dimensional modeling techniquesbring a variety of convenient and new audio and video entertainment to people, by the3Dmaps people can enjoy their trip freely, beautiful3D movies let people immersed in thefantasy and reality brilliant,3D games give players a new gaming experience. It can be saidthat the three-dimensional modeling gives us a better understanding of our world, and humanproductivity a leap.The obvious advantage of three-dimensional modeling is carried by a variety of strongmodeling software. In which the softwares,3dsmax and DirectX is a leader.3dsmax isresponsible for the3D model, DirectX is responsible for the show of model and animation,the combination of them can achieve the purpose of engineering design or publicentertainment. Moreover,3dsmax plug-in development that comes with this soft bring usersunprecedented freedom, but also its extensions greatly improved, at the same time DirectXSDK library function also allows users to improvement and optimization them.However, because the bridge between3dsmax and DirectX-X file’s fixed form bringsmany users the limitations, which makes them not free to import the model in3dsmax intoDirectX to display and use. For this problem, this paper first use3dsmax to establish the experimental three-dimensional model, and then study the bridge X file and improve it,todesign a new L file and then exporte the optimized L file through the3dsmax plug-in that isimproved, at the last, optimize DirectX’s loading and the rendering function to demonstratea new model animation files.
