是3d_rma数据库读写的程序，原来随数据库附带的读数据的程序读出的点有误，在此基础上做了一些修改，可以正确的读出。(3d_rma database is read-write procedure, the original database with the data attached to the procedure time to read out the points to be wrong, on this basis to do some modifications, you can read out the correct.)

转动的彩色立方体（1~2人）谭飞、吴颖颖 1) 绘制一个不停转动的彩色立体球，可以绕着任意方向旋转； 2) 采用一定的光照明技术，考虑环境光、反射光以及镜面光的作用； 3) 采用消隐算法，体现立方体表面的遮挡关系； 4) 具有较好的动画效果，消除闪烁现象； 5) 不可以采用OpenGL中的函数。 (Rotating color cube (1 ~ 2)谭飞,吴颖颖1) draw a non-stop rotation of the color three-dimensional ball, you can spin around in any direction 2) the use of certain lighting technology, consider the ambient light, reflected light and the mirror The role of surface light 3) the use of blanking algorithm, reflecting the relationship between cube block surface 4) has good animation effects, to eliminate flicker phenomenon 5) can not be used in a function of OpenGL.)

在MC（Marching Cubes）算法中,考虑了二义性的问题，是一个很好的程序(MC (Marching Cubes) algorithm, consider the ambiguity problem, it is a good program)

openGL编的类似3D MAx的程序代码，非常有用支持OBJ和3DS文件格式导入及渲染(openGL made similar 3D MAx procedure code, a very useful support OBJ and 3DS file formats import and rendering)

Prewitte边缘算子法(Prewitte Edge Operators)

DEM三维可视化的简单程序，利用Open GL实现。(DEM visualization of simple procedures, the use of Open GL implementation.)

基于PCL的三维点云模型表面主曲率估计的具体实现(estimation of the principal curvature)

网格简化程序基于3D三角网格简化，代码简单实用，而且非常有效的节省时间(meshsimplification is a C++ library and set of utilities for input, output, and basic manipulation of 3D triangle meshes. The goals of the code are ease of use and efficiency, possibly at the expense of some generality.)

说明：  三维均匀介质的高阶交错网格弹性波方程数值模拟（未加PML吸收边界条件），模拟结果以切边形式显示(Numerical simulation of three-dimensional homogeneous medium of high-order staggered elastic wave equation (not PML absorbing boundary conditions), the simulation results are displayed in the form of trimming)

说明：  自己编写的一个VC++程序，打开可执行程序后可以读取wave文件，此时程序将在客户区绘制波形图；之后可以计算短时能量、短时过零率和自相关函数，并且在客户区依次显示函数图像。(own VC prepared by a procedure to open executable wave after reading documents, this process will draw customers District waveform diagram; after short-term energy can be calculated, short-term rates and zero autocorrelation function, District customers in the sequence of images function.)
