Research On Technique Of 3D Graphic Engine Integrated Physical Features

As the growth of digital entertainment industry in China, the 3D game engine is becoming one of fast developing and far-ranging VR applications, but up to now the study of 3D game engine technology in China is still behind America and Japan. At present, the study of 3D engine system has been placed on the 863 plan. Research on 3D graphics engine the core of 3D game engine becomes hot at home and abroad.As relational academic study is ceaselessly developed, 3D graphics engine technology based on virtual reality is attracting more and more attentions, so computer animation based on physics modeling is proposed and expected to become a powerful 3D modeling and motion simulating technique. Although it is more complicated than traditional animation technique for application, it can really simulate so many physical behaviors in nature, which is just the disadvantage to traditional computer animation technique. Meeting the needs of 3D game engine, the research on effective dynamics simulation physically based modeling will be a way for researchers.The paper study on technique of 3D graphic engine integrated physical features, and primary tasks of the paper are described as followings:(1) To propose an improved multi-body collision detection algorithm based on dynamically aligned k-DOPs, which can detect the edges of object model, exactly determine the body's position and the interactive force actions, and effectively avoid penetrating. Our experiments demonstrate that the improved algorithm is better than previous one in accuracy and efficiency.(2) To master theoretical mechanics, and deeply investigate force analysis and motion rules, and then to build collision response model by momentum and angular momentum, finally to propose the multi-body motion simulating algorithm through combining theoretical mechanics with computer science.(3) To propose an improved Euler integral approach and integral controlling algorithm, which obviously reduces accumulated error and provides more accurate data.(4) Have analyzed the most current 3D graphic engines and the common model file formats, this dissertation designs a flexible and pluggable architecture that allows different components to be plugged in based on the requirements of an application or the capabilities of the device the application is running on, etc. and implements a 3D...
