| 摘 要： | 在科学计算可视化中，由于直接体可视化技术能够反映数据场内部的信息，所以它已经成为近年来研究的重点。通过应用三维纹理和可编程显卡的片段着色器（Fragment Shader）技术，在当前主流PC机上，实现了带有完整Phone光照阴影效果的三维数据场直接体可视化。仿真结果表明该方法在医学和军事学的三维数据场可视化中，能够实时生成高质量的体可视化图像。

| Abstract: | In visualization of scientific computation, because the volume visualization can display the inner information of 3D data sets, it has become researching emphasis in recently years. Byapplying the technology of 3D texture and Fragment Shader of programmable graphics hardware, the real time volume rendering of 3D data sets with full Phone shading model was realized on commodity PCs. The results show that the arithmetic can create real time high quality image in the medical and military realm. |
