sift 旋转方向法

本软件是用在SMT行业，回流焊设备设定制程文件时，把PCB的温度测试曲线(*.tdx)导入， 对该温度曲线的分析工具(英文版)。-the software is used in SMT industry, equipment set reflow process documents, PCB test the temperature curve (*. tdx) introduction, this temperature curve analysis tool (English).

一款手写数字识别系统，不错哦！学习的参考-A handwritten numeral recognition, it is true! Learning reference

关于直线的一个优化算法-This is an optimized algorithm about straight line.

clamped bspline function.

简单的二维图形，电路图，没什么特别，但实用-A simple two-dimensional graphics, schematics, nothing special, but the practical

注意： 1。tc支持16色，所以所读的图片要是16色图片 2。图片的的存放是从最后一行开始的，倒过来存放的 3。每行的字节数是4的倍数-attention : 1. Tc support 16 colors, and read the picture if two 16-color pictures. Photo storage is the last line from the start, the reverse of the three storage. Each trip is the number of bytes in multiples of 4

YUV数据的直接显示，用于那些对yuv不是很了解的人还是很有帮助的，请大家看看吧-YUV data directly, for those who do not know much about yuv person or helpful, If you look at it

OPENGL的开源版本，支持OPENGL2.0-Open-source version of the OPENGL support OPENGL2.0

一个完整的3DS文件导入到OpenGL中的源代码，代码简单易读，具有很好的参考价值.3DS file into a complete OpenGL source code, the code easier to read, have a good reference value.
