The Animation Rendering Technology And Application In Movies

The research we are involved in is rendering technology in three-dimensional animation. The animation rendering technology can be approximately divided into two categories: photorealistic rendering technology and non-photorealistic rendering (NPR) technology. It is a long time to development for photorealistic rendering technology, but the NPR technology is a new research domain in the world for computer graphics and image field in recently years. The NPR is based on photorealistic rendering technology, and it can render 3D graphics to cartoon style image and a certain artistic image. The silhouette edges are importment characteristic for three-dimensional model and represent the approximate model's shape. So, the technology of detecting 3D model silhouette is foundation information for NPR. It also render the 3D model to a line style image. The rendering technology of cartoon style belongs to NPR's field, and it is to be widely applied in animation telefile and movie area and development games.In this thesis, our research work mainly focuses on the following aspects, including:1 Perfecting and implement the algorithm of phong illumination modelAfter we research some illumintion models, we perfect and implement the phong illumination model and gain a nice photorealistic effect.2 Generating the NPR for the three-dimensional cartoon style using the Perfected phong illumination modelWe ameliorate the perfected phong illumination model and generate the new material that derectly rendering a chromatic cartoon image in a three-dimensional scene.3 The silhouette rendering technology for 3D modelWe have researched and compared these silhouette rendering algorithms that based on the theory and practice, developing the program of rendering silhouette using VC, and find anew method for rendering the 3D model's silhouette in MAYA. 4 The silumation for crowd animationWe also research and implement the algorithm and model for crowd behavior steering in 3D scene because of the whole project requiring, and silumate it later.At last, I summarize the work of this thesis and discuss the potential research topics in the future.
