cube mapping映射，里面有几个不同的3ds模型，还有几个不同的cube包围盒，大家可以看看。-cube mapping mapping, there are several different 3ds models, there are several different cube bounding box, we can see.

光线跟踪算法，能显示基本图形（球形，立方体，墙面），实现阴影，高光，反射，折射等效果-Ray tracing algorithm, can display basic graphics (sphere, cube, wall), to achieve shadows, light, reflection, refraction and other effects

识别魔方颜色，根据颜色不同识别输出相应标号，通过画矩形框的方式确定模块位置-Identification cube colors, according to the corresponding labels in different colors to identify the output to determine the position of the module by way of drawing a rectangle

通过knn分类算法识别魔方的色块颜色，加入是否识别成功判断，成功识别率比阈值法识别更高。有完整的备注(Through the KNN classification algorithm to identify the color block of the cube, the success rate is higher than the threshold method. Code has complete comments)
