OpenGL的学习程序，可以作为练习来分析，参考了Nehe的程序-OpenGL learning procedures, can be used as exercises to analyze, with reference to the procedures Nehe

VC+OpenGL做的,还有些ｂｕｇ,显示二维是根据高程的分层设色,三维能很明显表现出地形起伏.-VC OpenGL done, but also some bug show is based on two-dimensional layered elevation colors, 3-D can be shown very clearly undulating topography.

说明：  晶体相场方法对应合金的材料计算初始代码，初学者可取，很有帮助(The crystal phase field method corresponds to the material calculation of the initial code of the alloy, which is suitable for beginners and is very helpful.)

这是在vs2010下编译好的meshlab1.3.3。欢迎大家下载、试用。谢谢大家的支持！
