三维动画技术与三维虚拟技术的研究

Discussing of Differences Between 3-D Animated Technology and 3-D Virtual Technology

目前三维图形技术主要包括两大类 :三维动画技术和三维虚拟技术。该文的目的是研究两种技术的开发原理 ,并通过对两种技术的对比 ,进一步说明了三维虚拟仿真技术在实时性、交互性方面的优势。该文首先介绍了三维动画技术的应用原理、开发步骤 ,重点阐述了三维虚拟技术中的实时显示技术和交互技术 ,给出了虚拟仿真应用的开发方法及基于两种技术的应用实例 ,并对两种技术在实时性、交互性、时间性和三维建模效果等方面作了比较 ,最后展望三维虚拟技术的发展方向。

D technology includes two classes: 3-D animated and 3-D virtual. The article's intention is to study the principles of the two technologies, and to show the superiority of 3-D virtual in the real-time and interaction by the contrast. The principle and the developing steps of 3-D animated technology is presented and the real-time display technology and interaction of 3-D virtual are expatiated particularly. The development method of virtual and the two application examples are given. The differences of them in realtime, interaction, timeliness and 3-D modeling effect are offered. Lastly,the development direction of them are explained.
