虚拟场景中自动漫游路径的多分辨率规划

在三维虚拟场景中，为了避免自动生成的漫游路径所引起的视觉抖动和场景跳变现象，增强漫游的真实感，提出了一种基于样条小波的多分辨率漫游路径生成方法，详细叙述了根据自动漫游过程中通道宽度的变化采用不同的分辨率来构造漫游路径的原理和具体实现。最后，给出了一个在船舶设计三维虚拟环境中漫游的实例，进一步说明该方法能够获得更加流畅的漫游路径，使漫游中的场景变化更加连续平滑。

Navigation Path Multi-resolution Planning in Virtual Environment

In order to eliminate the vision dither phenomenon and enhance the immersed feeling in navigation in three dimensions virtual environment, a method on navigation path multi-resolution planning based on wavelets was proposed. The theory and realization of constructing navigation path by different resolution according to different width of navigation channels were introduced in details and an example about ship design was given. This method can help user to get more fluent navigation path, make scenes changing more smoothly and prevent vision dither phenomenon efficiently.
