摘　　要：给出了一个三维场景交互漫游系统的框架，着重介绍了三维空间漫游的方法及实现，包括键盘漫游、路径漫游、记录漫游路径、记录场景动画、碰撞检测等，并提出了按线性样条路径漫游时转角处抖动问题的解决方法。这些方法都已应用到作者开发的系统当中，收到了满意的效果。The paper presents a frame work of interactive walkthrough in 3D scene and focuses mainly on the implementing techniques of walkthrough in 3D space, including walkthrough by keyboard, walkthrough along path, recording path of walkthrough, converting video to files, collision detection. The problem of dithering when walking along the linear spline path and reaching a corner is solved. These techniques have been applied in the developed system and do well.
