基于GPU的流体力学仿真程序（需要Geforce3以上显卡）-GPU-based fluid dynamics simulation program (PII/400 need more graphics)

本程序主要实现场景的读入，纹理映射，使用最新的opengl编程方法。是基于着色器的！(The main achievement of the program reads the scene, texture mapping, using the latest opengl programming methods. Is based shader!)

6s辐射传输模型最新版6sv2.1的源代码和编译后生成的可运行文件，编译是在ubuntu18.04下进行的，生成的运行程序名为6sv2.1,不带有输入参数说明，关于参数输入问题，可以在6s官网上下载指导手册，或是查看源代码里main.f文件(The source code of the 6S radiation transmission model and the compiled files are compiled under ubuntu18.04, and the generated run program is named 6sv2.1, and the actual measurement can be used.)

说明：  实现邓肯-张本构模型二次开发的Fortran程序(Fortran Program for the Second Development of Duncan-Zhang Constitutive Model)

用opengl和visual c++ 实现的例子系统的演示，漂亮的烟花效果-use opengl and visual realization of the c examples of the display system, the beautiful effect of fireworks

求解一元三次方程的Fortran源代码，自己试了试，可以用(Fortran source code for the three equation of a dollar, you can try, you can use)

用API写的OPENGL的程序-use the OpenGL API to write procedures

OpenGL tutorial. I found it on the net and it was pretty usefull to me, i change it a bit. try it out its awesome.

说明：  计算球体重力及重力梯度异常，已知地下球体的相关参数，即可正演该球体的重力及重力梯度(Calculation of gravity and gravity gradient anomaly of sphere)

通过简单了解slc文件格式，进行文件读取操作。通过VTK工具包读取所需slc文件
