摘要:本文通过介绍使用三维仿真动画技术，在天津市的典型历史风貌建筑的综合改造技术示范工程中的实际应用，向读者展示了计算机图形技术在既有建筑的保护过程中发挥的巨大作用。本文以天津市典型历史风貌建筑“原法国工部局大楼”和“原盐业银行”的三维仿真动画的制作为实例，详述了从资料的准备、三维模型的建立、绘制纹理和调节材质到最后渲染输出的具体制作过程。

Abstract: The thesis introduces the 3D Animation Technology which is practically applied to Comprehensive Transformation Technology Demonstration Project with representative buildings of historical style and features in Tianjin.By way of illustration, the manufacturing process of the 3D Animation of"The French Ministry of Chemical Industry Bureau"and"Salt Industry Bank", both of which have reflected typical features of the Historic Architecture.Meanwhile, the thesis also recounts the process of manufacture including preparing materials, establishing three-dimensional model, drawing three-dimensional texture, adjusting the effect of materials as well as rendering output.Finally, it comes to the conclusion that the technology of the computer graphics exerts a tremendous impact in protecting existing buildings.
