Abstract
It introduces U3D (Universal 3D) file format and the method to embed U3D data into PDF to produce a 3DPDF file which can be browsed by PDF reader. It analyzes the architecture, mechanism and data structure of U3D. C++ language is used to translate 3D model to U3D file and then embed U3D into 3DPDF file. A 3D geology model which is expressed by Geo3DML (Three Dimension Geological Model Data Transfer Format), which has been published by CGS (Chinese Geological Survey) has been translated into 3DPDF file. The results file is small in file capacity, good in visualization, convenient in operation. U3D file format is appropriate to express a variety of complicated 3D models, and expand the application of 3D computer models when embed into 3DPDF.
