The Analysis And Implementation Of Urban Planning And Design

With the development of computer technology three-dimensional animation technology has come into being an emerging technology, and gained rapid development after the birth of digital art. As a tool to simulate objects in the real life, the three-dimensional graphic image has received considerable attention. In recent years, with level of city planning and construction being constantly improved, computer technology plays an increasingly important role in design concept and projects'showing. Digitization of urban planning and design, widen the thoughts of designers to reach the goal of perfect combination of design and art, and also enrich their technique of expression to make projects more vividly displayed. What's more, digitization itself has a positive meaning in integration of city planning with art and computer, and provides a wider development space for art designer and computer enthusiasts.Nowadays, digitization has gone through every segment of urban planning and design, such as project design, display, discuss, implement and management, which gives more direct understanding to planner, manger, and residents, and attracts more people to take part in urban planning.This paper takes planning and design methods and practical experience of the "Olympic" project as the study content. Urban planning and design concepts, unique feature and spatial distribution of the project, digital media technology are analyzed objectively, and the method for realization of urban planning is ultimately determined. The paper introduces the research progress of virtual reality and urban planning and design both home and abroad. The planning background and requirement for effect of the project are put forward. The target is achieved mainly by digitization of urban planning and design:work out planning proposal, determine the virtual reality path (camera animation path) based on geometric alternative model production line, do three-dimensional modeling design (including simple and refined models) to meet the needs of lens line, and arrange scene and design material and lighting as the model requires, then use VR agency to produce environmental agents for large layout and plants. After rendering the output, the digitization is completed.
