摘要:: 随着虚拟现实技术和人机交互技术的迅速发展，蒙版擦除动画成为一种新兴的互动方式，并被用于大量游戏软件中. 其中，实现三维场景中用户任意需求形状的动画擦除，有望进一步提升游戏的交互体验，具有较为重要的现实意义. 现有的蒙版擦除动画一般都是在二维空间内通过抠图等技术实现的，无法直接移植至三维空间. 基于此，本文提出了一种三维场景中基于模板的个性化蒙版擦除动画实现方法. 首先将包含用户个性化需求形状的栅格数据转化为易于处理的矢量数据，并作为模板存储起来. 然后采用三维空间正射投影分层绘制的方法实现三维空间内的个性化蒙版擦除动画效果. 实验证明，本文方法可以实现三维场景中用户任意需求形状的自动擦除且具有较高的擦除效率.

Abstract:: With the rapid development of virtual reality and human-computer interaction technology, the erasure animation becomes a new form of interaction and has been used by lots of virtual computer games. A three dimensional(3D) erasure animation will give a high virtual interaction and has an important significance to virtual computer games. Existing erasure animations mainly focus on two dimensional animations. They can’t be used in a 3D scenario directly. In this paper, we propose a template based 3D personalized erasure animation method. There are two parts in our method. Firstly is the template making. We transform raster data, in which there are erasure shapes, into vector data and do the matrix generation and affine transformations for these data and then store them as templates. Secondly is our erasure animation. We use LOD technique to give a quickly and variedly erasures through simple translations and rotations. Experimental results show that our method can show erasure animations efficiently and effectively.
