3D打印源码，引擎源码，包括头文件和库文件(3D print source code)

说明：  能花线，圆，矩形，正方形 能选者颜色，能选者填充的背景图案 (can spend line, circle, rectangle, square color who can be elected, who can be elected to fill the background logo)

使用VisualC++ Win32应用程序开发的一个OpenGL程序，实现雾的效果。(Using VisualC++ Win32 application development an OpenGL program to achieve the effect of fog.)

说明：  访问最底层LOD模型路径，打开后获取顶点数据和PirmitiveSet，重绘模型的三角面片(Visit the bottom LOD model path, open it, get vertex Array and PirmitiveSet, and redraw the triangle of the model.)

D3D创建球体并且加贴图的例子，可以用来做星球(Sphere, and add texture to create D3D example, can be used to make the planet)

NVIDIA实现硬件阴影贴图的源代码 需要硬件支持DX8.1的显卡。(NVIDIA hardware shadow mapping of the source code necessary hardware support 24x graphics.)
