The accelerated algorithm of volume rendering based on textures mapping and the wavelet-based multiresolution volume rendering in network are performed by using OpenGL 3D visualization technique. From the point of view of computer graphics, 3D visualization mechanism of volume rendering based on OpenGL textures mapping is studied, including modelview transformation, projection transformation, perspective division, viewport transformation and the ways to embed textures mapping and blending in above four transformations.

利用OpenGL三维可视化技术实现了本文所提出的基于纹理映射的体绘制加速算法和网络环境下基于小波的体数据的多分辨率体绘制，并从计算机图形学的角度，研究了基于OpenGL纹理映射技术的体绘制的三维可视化流程，包括OpenGL的模视变换、投影变换、透视除法、视区变换，以及纹理的定义、映射与融合等步骤在上述四个变换中的嵌入方法。

In addition, the algorithm has comprehensive potential application in computer graphics, computational geometry and so on. To fast and precisely select nodes and elements, some transformation functions which are implemented substitute the OpenGL's API functions, then facilitate dynamic interactive query.

为了精确、快速的选择节点和单元，作者通过对OpenGL拾取选择技术内部实现细节的深入分析，开发程序实现了一些变换函数，解决了OpenGL提供的API函数不能对节点单元的精确任意拾取的问题，并实现了节点单元的动态交互查询。

Take some of the recent academic research: computer graphics allow us to predict whether small molecules will fit into or react with larger ones - this could lead to a whole new generation of drugs to control disease; chemists are also studying the use of chemicals to trap the sun's energy and to purify sea water; they are also investigating the possibility of using new ceramic materials to replace metals which can corrode.

以一些近来的学术研究为例，计算机呈像技术使我们能预言是否小的分子能与大分子匹配结合或反应？这可能会导致一种全新的制造控制疾病的药物的技术；化学家们也正在研究利用化学物质来获取太阳能和对海水进行纯化；他们也正在研究用新的陶瓷材料来替代易腐蚀的金属材料的可能性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
