离散元软件3DEC软甲隧道分析实例，考虑了节理分布情况以及各种支护结构单元，建模技术较高，有助于避免自带生成器的伪节理影响(Discrete element analysis software 3DEC soft-tunnel instance, consider the joint distribution as well as supporting a variety of structural units, higher modeling techniques to help avoid pseudo generator comes joints affected)

三维图形的切割就是要把三维网格模型进行切割然后以等值线显示切面上的数值。运用适当的三维图形显示技术和可视化C++编成技术来实现的。(Three-dimensional graphics of the cut is to take three-dimensional grid model and then cut the contour values on the display section. Use of appropriate three-dimensional graphics display technology and visualization techniques to compiled C++ implementation.)

说明：  采用％中值滤波％otsu 自动阈值计算％图像二值化％采用腐蚀的方法进行边缘检测(using median filter%% Otsu automatic threshold calculation% image binarization% of the corrosion methods Edge Detection)

shape from shaping 3D重构(shape from shaping 3D reconstructed)

相机在轨道上沿轨道（管状）运动； 右键可以选择不同视角观察和退出，有两个视角；(Camera on the track along the orbit (tubular) movement Right you can choose a different perspective and exit, there are two perspectives )

MATLBA 信道仿真,完成信道卷积码循环码的编译码 不错的(MATLBA channel simulation, complete channel convolution code of cyclic code compiled code is good)

osg 海面上添加小船，有月亮，有风，有倒影(OSG adds boats to the sea, with the moon, the wind and the reflection)

说明：  Shewchuk的三角剖分算法，能剖分带孔的离散点，PII233 剖分一百万个离散点只需20秒。(Shewchuk 涓夎鍓栧垎 the algorithm, can cut in half the belt hole the separate spot, PII233 cuts in half 1 million separates only to need for 20 seconds. )
