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.

stm32识别颜色的算法程序源代码，对于不同颜色的识别准确率极高(STM32 color recognition algorithm program source code)

Description CC非常喜欢化学，并且特别喜欢把一大堆液体倒在一起。 现在CC有n种液体，其中m对会发生反应，现在她想把这n种液体按某种顺序倒入一个容器内，让她获得最刺激的体验，使危险系数尽量大。 我们可以这样计算危险系数，一开始容器内没有任何液体，危险系数为1。每次液体倒入容器时，若容器内已有一种或多种液体会与这种液体发生反应，则危险系数会乘2，否则危险系数不变。 请你求出把这n种液体倒在一起的最大危险系数。(most dangerous numbers)

AD7671采集,并行16位采集，采集速率为1M，CPU为STM32F407(AD7671 collection, parallel 16-bit capture, capture rate of 1M, CPU of STM32F407)

说明：  STC15W4K48S4串口打印程序,利用硬件串口..(use; utilize; make use of; take advantage of)

同时使用STM32三个串口的接收与发送，串口1使用printf(),串口2使用u2_printf(),串口3使用u3_printf().接受采用定时器中断超时，5ms未接收到数据认为本次接收结束，置位相应的标志位，主程序检测并处理接收数据。(STM32 simultaneously receive and send three serial, serial port 1 to use printf (), 2 serial ports use u2_printf (), 3 serial ports use u3_printf (). Accepting timer interruption timeout, 5ms does not receive data that the receiving end of this, set the appropriate flag, the main program to detect and process the received data.)
