A variety of button controls, and I would like to offer the same beginners to learn, reference

说明：  《thinking_in_cpp》，计算机大师Bruce Eckel的著作，学习C++的顶级材料(&quot Thinking_in_cpp&quot , Master Bruce Eckel computer books, learning C++ of the top material)

fluent 中蒸发、冷凝模型的初步udf代码以及验证case(fluent in evaporation, condensation model code, and verify the case initially udf)

说明：  串口重定向，调试要用到，非常重要。printf函数重定向。(Serial port redirection is very important for debugging. Pritf function redirection.)

基于osg的场景漫游代码,OpenSceneGraph（简称OSG）使用OpenGL技术开发，是一套基于C++平台的应用程序接口（API），它让程序员能够更加快速、便捷地创建高性能、跨平台的交互式图形程序。它作为中间件（middleware）为应用软件提供了各种高级渲染特性，IO，以及空间结构组织函数；而更低层次的OpenGL 硬件抽象层（HAL）实现了底层硬件显示的驱动。
