摘　　要：虚拟现实技术已广泛应用于考古领域,为文物和古环境的再现提供了平台。X3D作为VMRL语言的继承版本,是新的3D图形规范。本文以X3D/VRML为工具,结合现有的虚拟现实技术对三维虚拟古场景的开发原理和技术进行了研究。综合各方面专家的研究成果与文物考古成果,以精确的地理位置再现金沙地区三维古场景,并运用X3D的消息映射机制以及Java对VRML的控制实现了交互功能。基于X3D制作的虚拟现实场景文件体积小,方便网上传输;其平台无关性,便于实现交互功能。The virtual reality technology has been widely used in archaeology and it provides a new platform to the reappearance of cultural relics and ancient environment. Inherited from VRML, the Extensible 3D （X3D） has been improved a lot in many aspeers and is the next generation 3D graphic criterion. Combining the existing virtual reality technology, the paper studies the development principle and technology to construct the 3D ancient scene based on X3D/VRML. The paper integrates the production that experts in each field studied in Jinsha to confirm the exact ancient scene. At last the paper achieves interactive function by using the mapping messages of X3D and the control to VRML scripts by Java. The virtual scene file based on X3D is smaller, so that it is convenient to be transported through Intemet. It has nothing to do with the platform and can carry out interactive function easily.
