Design And Realization Of 3D Graphics Animation System

With the development of computer technology has become more and more widespr ead application of image processing technology, particularly the application of three-di mension simulation and emulation technology favored alternate, however due to the co mplexity of the three dimensional graphics, animation of three dimensional graphics ani mation design and engines rendering of the scene became a problem in modern graphics, has become a hot area for research on three dimensional graphics.Due to the relevance and specificity of three dimensional graphics engine technolo gy, making three dimensional graphics engine in graphics processing as a whole has bee n widely used in the field. Currently not only in manufacturing simulation, game develo pment industry, control, or in various computer graphics development process, are rarel y on the API low-level graphics three dimensional graphics, instead of using three-dime nsion graphics technology for development.Reasonable scientific use three dimensional graphics engine technologies could make the graphics developer saves a lot of time, eng ine code reusability makes intelligent simple fabrication of three dimensional graphics. So how do we develop a set of practicability and efficiency of three dimensional graphic s animation system, how to make three-engine in the application process even more con venient for developers, more efficient upgrade, engine code powerful was the purpose a nd value of this research.Based three dimensional graphics rendering technology, this thesis mainly against t he Romans designed three dimensional graph animation engine and design research of r eal-time scene rendered with a direction, key elements include:1. Presentations were made to the current status of the study of three dimensional g raphics, analysis of the current development situation and development trend of three-di mensional graphics engine;2.according to the three dimensional graph research results, analyzed the prevailing characteristics of three dimensional graphics engine, and engine architecture was divide d, completed the three-dimensional animation system design of the structure and functio ns of the engine, the Romans engine was functional module of study;3. the system of three dimensional graphics on large vegetation rendering on the cu rrent difficulties were studied, including vegetation modeling, shading, lighting and volume rendering;4.Impostor graphics processing technology is used to solve the difficulties faced in the process of three dimensional graphics animation solution algorithm is proposed, and integrate applied to the fabrication of three dimensional graphics animation drawing alg orithm proposed systems for large-scale vegetation rendering solution.This thesis not only conducted a study and realization of three dimensional graphic s animation system, three dimensional graphics engine also conducted an in-depth discu ssion on the key technology of the animation, and gives suitable methods of production design, realization and improvement of algorithm for three dimensional engine has a cer tain innovation.
