Script node embedded JavaScript program can model the natural movement of an object. The paper, based on the VRML technique, introduces the method to display the special effects, such as water-waving, water-flowing and planar imaging and so on.

• 通过在Script节点中嵌入JavaScript脚本程序,模拟自然型体的运动特点,给出了基于VRML的波浪起伏、水流前进和平面镜像等特殊显示效果的实现方法。
