Digital Image Filtering

这个也是图形学的一个作业，不过功能比较全面和强大，可以完成基本几何体的造型、多边形化，可以设置场景光源并进行光线跟踪渲染等。启动类为final_3d.Final_3D-this is a graphics operation, but function more comprehensive and powerful, can be completed basic geometric shapes, polygons, and can be installed Scene light source and Ray Tracing rendering, etc.. Start category final_3d.Final_3D
