摘要(Abstract)：

针对目前三维地质模型数据格式繁多,交换困难的问题,该文介绍了中国地质调查局颁布的三维地质模型数据交换格式标准(Geo3DML)及其向3DPDF文件转换的必要性和实现的技术途径。首先简单介绍了Geo3DML的背景、制定过程、标准概况与试用情况;然后介绍了3DPDF的背景与用途;接着介绍了3DPDF所依赖的U3D格式的背景;最后介绍了用C++编程实现Geo3DML向3DPDF转换的技术途径和一些关键技术以及对数据输出质量控制的选项设置方法。转换结果能够较好地表达三维地质模型几何特征和属性特征。

关键词(KeyWords)： 三维地质模型;数据交换格式;Geo3DML;3DPDF;U3D
