摘  要
 
 三维动画又称3D动画，是近年来随着计算机软硬件技术的发展而产生的一项新兴影视艺术。随着三维动画对计算机技术的越来越高的需求，一些专业的三维动画软件相继被开发出来并不断更新与完善，加上计算机硬件技术的迅速发展，这些都大大促进了三维动画的发展。如GPU的开发大大提高了三维图象处理的效率，也使三维动画的质量得到很大提高。
 在本次毕业设计团队分工中，本人结合自身擅长，将工作重心定位于模型与后期特效的制作。因此^论文多角度探讨了三维动画制作过程中建模技巧与后期特效应用等。本片计时共十分钟，是一部全部由电脑完成的三维动画短片。在制作过程中充分利用了现代计算机技术——在硬件部分，采用了新型高配置计算机、数绘板、GPU图形处理器等；在人物的三维建模方面利用先进的Maya2010三维动画开发软件，结合Z-brush、VUE等建模软件，进行了剧中角色和场景的三维建模、材质选择、贴图和动作设计等；在特效和渲染中利用RUINS和 Ferryball两个软件，调用GPU进行刚体破碎的动力学计算和图象渲染，大大提高了运算速度和画面质量；在后期处理方面，综合了多种后期处理软件，如Shake，AfterEffect，Combution等软件，结合运用了大量特效滤镜，形成了片中精彩纷呈的各处效果。
 《重塑》是一部科幻题材的三维动画短片，描述了若干年后的桂林，由于气候和人为因素的影响，已然变为一片人迹罕至的荒漠。片中主人公却执著地想改变环境，梦想着某一天绿色重归大地，并日复一日为此付出艰辛劳动。本片旨在通过主人公近乎悲凉的结局，启发着人们开始思索：逝去的一切，是否都能重塑？

Abstract
    3D （3-dimensional） animation is a new style of movie/TV art, which is developed together with the development of computer technology. Computer-based 3D animation means that the movie is totally produced by computer. Computer science (hardware and software) step forward very quickly in recent year, a number of 3D animation tools have been developed, and the old 3D animation software have improved much. For example, GPU  (Graphic Processing Unit) is a new computer technology, it has been widely used in bulk  scientific calculation, and 3D animation since it has been invented. This technology largely improved the quality and effection of 3D animation.
 In the working group that finish this 3D movie, the main task for me is modeling and effects because of my expertise in 3D modeling and application of effects. The dissertation discuss the story design, 3D modeling, material, effects applying and productive process of this 3D animation. “Rebuild” is a ten minutes computer-based 3D animation. For 3D modeling of roles and scenes, we use Maya, Z-brush , VUE as main development tools. The dynamic calculation and image rendering were completed by use RUINS （software） and Ferryball （software） calling GPU.  The using of GPU greatly improved the efficiency of image processing and quality of the image in the movie. “Rebuild” is a science fiction.
 The story happens in Guilin sometime in the future. Because of the climate change and environment pollution, Guilin has had become a desert, no trees, no water, just sand and bare mountains.  The movie tell a story about a scientist who has a dream that is to recover the beautiful Guilin like before. He had paid great effort to do that, but failed. “Rebuilt” is an alert that remind people to think “Does the earth environment can be rebuilt, if it has been polluted, damaged, ruined?”

Key words ：3-D animation; Modeling, Effects; Breaking up of rigid body; GPU, Rebuilt
