图形硬件辅助的快速数据场体绘制方法

A GL/OPENGL BASED APPROACH FOR REGULAR DATA FIELD VISUALIZATION

本文对规则数据场的体绘制过程进行了讨论，在此基础上给出一种图形硬件辅助的体绘制方法。该方法通过ＧＬ／ＯｐｅｎＧＬ提供的函数和接口，利用高性能图形工作站ＳＧＩ的硬件支持，快速实现规则数据场的体绘制。

The process of volume rendering regular data field in projection method is discussed in this paper.An approach for volume visualizating regular data field that based on the functions of GL/OpenGL in SGI workstation is described.The efficieny of rendering is increased becaues of the assistance of graphic hardware.The implementation of the approach,together with some exprimental results,are given in the paper.
