本文提出了一种在虚拟3D空间中漫游的交互技术，用户可直接在场景中绘制预期路径，虚拟角色会自动沿该路径移动。系统通过将屏幕上绘制的笔画投影到3D世界中的行走表面来计算路径。利用这种技术，用户不仅可以用一笔指定目标位置，还可以指定要走的路线以及目标处的摄像机方向。使用集成显示屏的平板电脑对一个原型系统进行了测试，实验结果表明该技术可以增强现有的漫游技术。
This paper presents an interaction technique for walkthrough in virtual 3D spaces, where the user draws the intended path directly on the scene, and the avatar automatically moves along the path. The system calculates the path by projecting the stroke drawn on the screen to the walking surface in the 3D world. Using this technique, the user can specify not only the goal position, but also the route to take and the camera direction at the goal with a single stroke. A prototype system is tested using a displayintegrated tablet, and experimental results suggest that the technique can enhance existing walkthrough techniques.
