Description: OpenGL是美国SGI公司最新推出的一套开放式的三维图形软件接口，适用于广泛的计算机环境，从个人计算机到工作站，OpenGL都能实现高性能的三维图形功能。OpenGL本身不仅提供对简单图元的操作和控制，还提供了许多函数用于复杂物体的建模。但是，我们通常喜欢使用AutoCAD和3DS及3Dmax等工具来建立模型，并且我们已经有了很多这样的模型，那么我们如何才能资源共享，避免重复劳动呢？利用CAD图形标准数据交换格式—DXF格式，我们就能很容易地实现资源共享，而不需要重复建模。 -SGI OpenGL is the company's new open-3D graphics software interface, applied to a wide range of computing environments, from the personal computer workstations, can achieve high-performance OpenGL 3D graphics capabilities.

However, we usually prefer to use AutoCAD and 3DS max and tools to build models, and we have many such models, then how can we share resources and avoid duplication of work?

Description: The Swendsen-Wang Cuts algorithm is used to label atomic regions (superpixels) based on their intensity patterns using generative models in a Bayesian framework. The prior is based on areas of connected components, which provides a clean segmentation result. A performance comparison of the Swendsen-Wang Cuts algorithm with the Gibbs sampler shows that our algorithm is 400 times faster.

Description: Java 3D is a high-level 3D graphics API based around the construction of a scene graph data structure that contains the objects that appear in the 3D scene. Java 3D topics covered here include how to build your own 3D models, load existing models, create detailed landscapes, display beauti- ful skies and backgrounds, and have users navigate through the scene, bumping into things as they go.

Description: 压缩传感是一个从2006年左右开始兴起的研究领域，它关注于如何采样信号，也就是信号的采样方式或者压缩方式。通过设计一种特殊的采样方案，可以使得采样频率降低为信号的“信息率”，而不是传统的奈奎斯特采样率，于是，实际的采样率可以大大低于奈奎斯特频率，却只损失很少的信息量，依然保持了充足的信息量足以恢复出采样前的原始信号。这个研究思想挑战了奈奎斯特频率的理论极限，会对整个信号处理领域产生极其深远的影响，同时，信号处理的许多应用领域也会随之发生根本性的发展和变化。
-Compressive sensing (CS) is an emerging fi eld based on the revelation that a small
collection of linear projections of a sparse signal contains enough information for sta-
ble, sub-Nyquist signal acquisition. When a statistical characterization of the signal
is available, Bayesian inference can complement conventional CS methods based on
linear programming or greedy algorithms. We perform approximate Bayesian infer-
ence using belief propagation (BP) decoding, which represents the CS encoding matrix
as a graphical model. Fast encoding and decoding is provided using sparse encoding
matrices, which also improve BP convergence by reducing the presence of loops in
the graph. To decode a length-N signal containing K large coeffi cients, our CS-BP
decoding algorithm uses O(K log(N)) measurements and O(N log2
(N)) computation.
Finally, sparse encoding matrices and the CS-BP decoding algorithm can be modifi ed
to support a variety of signal models and measurement noi

Description: 在Windows系统中，安装GLUT库：打开glut-3.7.6-bin.zip，取出glut.h，glut32.lib，glut32.dll，分别放置。
使用Visual Studio C++编译已有项目工程，并修改代码生成以下图形：
在此基础上，修改各顶点颜色，使得每个顶点颜色不一样，多边形内部颜色渐变。
操作方法和实验步骤：
1.使用GL_POLYGON模式绘制白色的多边形，由于所绘多边形为凹多边形，故从最左上角的点开始绘制，以防得到不可预测的图形。注意求得各凹角(reflex convex)处的顶点坐标。
2.下面考虑修改各顶点颜色。首先多边形绘制改为从位于图形中心的(0,0)处开始，并设为白色。
3.此后对于六个凹角处的顶点分别设定其颜色为黄色，绿色，青色，蓝色，洋红色及红色。默认状态下多边形将出现渐变的效果。
4.此时运行程序将得到如右图所示效果：为此，我们再次绘制前面所绘制的第一个多边形顶点，即可得到所要求图形。
-In the Windows system, install the GLUT libraries: Open glut-3.7.6-bin.zip, remove glut.h, glut32.lib, glut32.dll, were placed.
The use of Visual Studio C++ compiler has been the project works, and modify the code generates the following graph:
On this basis, modify the vertex colors to make different colors for each vertex, polygon internal color gradient.
Operational methods and experimental steps:
1. Use GL_POLYGON draw white polygon models, as painted concave polygon as a polygon, so starting from the most upper left point rendering, in case the graphics to be unpredictable. Note to seek the concave angle (reflex convex) at the vertex coordinates.
2. The following consider amending the vertex colors. First, change from the rendering polygon graphics center located at (0,0) at the beginning, and set to white.
3. Then for the six respective concave corner vertex set its color to yellow, green, cyan, blue, magenta and red colors. Polygon will appear by default gradient e
