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:
Existing erasure animations mainly focused on two-dimensional animations, so they couldn’t be used in three-dimensional scenes directly. Aiming at this problem, a template-based and personalized erasure animation method in three-dimensional scenes was introduced. In our method, firstly, the erasure shape was extracted from the image data and semanticized as a template so that it can be used conveniently in erasure animations. Then the three-dimensional orthographic projection method was used to realize erasure animations. Experimental results showed that our method can realize a real-time animation for various kinds of users’ erasure shape in three-dimensional scenes efficiently.
