dsp 方面的知识，拿来大家多学习学习，共同提高，共同进步(dsp knowlege)

多点聊天系统的源代码，用VC++写的，非常好用。(Multi-point chat system, source code, written using VC++, very easy to use.)

采用VB6.0编程的MD5加密算法。MD5就是采用单向加密的加密算法，对于MD5而言，有两个特性是很重要的，第一是任意两段明文数据，加密以后的密文不能是相同的；第二是任意一段明文数据，经过加密以后，其结果必须永远是不变的。前者的意思是不可能有任意两段明文加密以后得到相同的密文，后者的意思是如果我们加密特定的数据，得到的密文一定是相同的。(Using VB6.0 programming of MD5 encryption algorithm. MD5 is the use of one-way encryption algorithm, for MD5, there are two characteristics is very important, the first is any two plaintext data encrypted ciphertext, later not to be the same second is an arbitrary piece of plaintext encrypted data, then, the results must always be the same. The meaning of the former is unlikely to have any two plaintext after getting the same ciphertext, which means if we encrypt specific data, the encryption must be the same. )

Unicode编码转换器，输入Unicode字符，可以转换成相应的汉字，使用VC6.0编写，有MFC界面，代码测试绝对可以正确运行。(Unicode encoding converter, input Unicode characters can be converted into the corresponding Chinese characters, using VC6.0 prepared with MFC interface, code testing can definitely run correctly.)

点云数据转换文件。可以将PCL转换为PLY文件，反之亦然。其中用到了点云库PCL的代码。(Point cloud data file conversion. PCL can convert PLY files, and vice versa. Which uses a point cloud library PCL code.)

计算机图形学 图形填充算法 有序边表算法 通用性强 新边表建立有新意(Computer graphics graphics to fill algorithm ordered edge list algorithm versatility of the new side table to establish innovative)
