DeMatrix: 生物分子结构pdb文件的变换矩阵提取程序的源码。pdb文件可显示三维生物分子结构，并且用其他程序显示，显示后可以随意变换，这个程序可以抽取变换的数学矩阵，用于变化同类pdb.-DeMatrix: bio-molecular structure pdb file extraction program source code transformation matrix. pdb file can be displayed three-dimensional structure of biological molecules, and other programs to use a display that can be freely after the change, this program can extract the mathematical transformation matrix for the change in the same pdb.

opengl入门，画图的各种步骤比较详细-opengl portal, drawing the various steps in more detail

创建OpenGL窗口的基本代码，自己觉得很有用，与大家分享。-Create OpenGL window for the basic code, feel useful, to share with you.

在vc的环境下关于mfc的opengl的窗口设置的简单例子,程序很简单,对opengl的初学者应该很有用.-in vc environment on the opengl mfc the window set up a simple example, the procedures are simple, right opengl beginners should be very useful.

Bezier Curve / Bezier Surface renderer in OpenGL. Press 1-4 to control level of details. Press l to toggle outlines. Press s to toggle smooth. Project was built using XCode, but should be easily portable to other platforms. See SceneFileFormat.txt for scene file instructions.-Bezier Curve/Bezier Surface renderer in OpenGL.

在vc环境下运用opengl绘制的颜色立方体。这是一个采用光滑着色的立方体， 立方体的表面从一角的一种颜色渐变到正对角落的另一种颜色，还可以用键 盘上的箭头键来旋转该色彩立方体，观察它的各边各角。-environment in vc use opengl rendering color cube. This is a sleek-colored cube, the cube corner from the surface of a color gradient is to the right corner of a different color, you can use the keyboard arrow keys to the rotation of the color cube, it"s the observation of the edge angle.

该方法的想法是在亮度阈值二值化 B 变异从一个点到另一个点基于本地的标准偏差。阈值亮度点 (x，y) 的计算公式如下： B (x，y) = m (x，y) + ks (x，y)， 其中 μ (x，y)-平均值和 s (x，y)-给附近居民样本的标准偏差。邻里的大小应该是最小的但保持局部细节。同时，大小应足够大，以减少噪声对结果的影响。K 值确定边界的对象是对象本身采取的哪一部分。K 值 =-0.2 给对象的分离效果相当好，如果他们都提出了在黑色，而 k 值 = +0.2，-，如果对象是白色的。

利用opengl生成水面和地形，能用键盘进行控制漫游效果。这个程序十分具有参考价值，生成的效果是非常不错的！-use opengl generate topographic surface and can use the keyboard to control the roaming effect. This procedure is very valuable, and the production was very good!
