The paper shows how to generate shadows of different bodies in virtual scene by VRML,Java /JavaScript,projected algorithm onto a flat ground and generating dynamic shadows. Thereby,the VRML scene becomes a more realistic display.

• 利用VRML技术J、ava/JavaScript技术、平面投射阴影算法和动态阴影生成方法实现了虚拟场景中不同形体的阴影效果,从而极大地增强了VRML场景的真实感。
