Description: 国外程序员编写的基于OpenGL的3D地形引擎。
errain Engine
I started working on a terrain engine around October 2000.
I was deeply moved by screenshots from black and white :)
My intention and main goal was to create something visually stunning.
This meant writing a terrain texture-generator, and working hard to find good textures and blending modes.
The outcome is an engine that hold a (supposedly) 1km by 1km piece of terrain with very high accuracy.
There is no triangle-cutting algorithm employed, simple brute-force. I use a large terrain texture and
a tiling detail texture. There s a skybox and the terrain reflects on the water.
I used OpenGL for this one, employing the OGLC skeleton to avoid most of the opengl-win32 business.
You can move through this world using descent keys (a,z, keypad). use w to switch to wire-frame and d to render without the detail texture.-foreign programmers prepared by the OpenGL-based 3D terrain engine.

Description: Natas 病毒，长度 4744 字节，有的地方有把它称为 4744 病毒，由于病毒是用了变型技术，本身的形态几乎有无穷多种，使杀毒软件总漏掉一两个，不知什么时候又冒了出来，所以又称它为‘幽灵王’。-Natas virus, the length of 4,744 bytes, in some places it is called the 4744 virus, because the virus is a variant technology, the form itself almost infinite variety, so that anti-virus software omitted from the total 12. I do not know what time has run out, so the call 'ghost Wang'.

Description: 数字通信系统的设计及其性能和所传输的数字信号的统计特性有关。所谓 加扰技术，就是不增加多余度而扰乱信号，改变数字信号的统计特性，使其近 似于白噪声统计特性的一种技术。这种技术的基础是建立在反馈移位寄存器序 列（伪随机序列）理论之上的。解扰是加扰的逆过程，恢复原始的数字信号。 如果数字信号具有周期性，则信号频谱为离散的谱线，由于电路的非线 性，在多路通信系统中，这些谱线对相邻信道的信号造成串扰。而短周期信号 经过扰码器后，周期序列变长，谱线频率变低，产生的非线性分量落入相邻信
道之外，因此干扰减小。 在有些数字通信设备中，从码元“0”和“1”的交变点提取定时信息，若
传输的数字信号中经常出现长的“1”或“0”游程，将影响位同步的建立和保 持。而扰码器输出的周期序列有足够多的“0”、“1”交变点，能够保证同步 定时信号的提取。
-digital communication system design and performance and the transmission of digital signals on the statistical characteristics. The so-called scrambling technology is not to increase the degree to disrupt redundant signal, digital signal change the statistical properties it is similar to white noise statistical characteristics of a technology. This technology is based on feedback shift register sequences (pseudo-random sequence) of the above theory. Decryption is the reverse of the scrambling process, the restoration of the original digital signal. If the digital signal is cyclical, the signal spectrum of discrete lines, as the nonlinear circuit, in multi-channel communication system, these lines of the adjacent channel signal causing crosstalk. And the short-cycle signal after scrambling
