光线跟踪测试基准，BART的主要贡献是提供了三幅参数可变的栩栩如生的场景，以此可以用来比较不同的光线跟踪算法的性能。对于看上去很相似图像，我们也设计了方法用来比较相似图像的质量有何不同。-Light tracing test standards, BART is the main contribution of provide for three of the variable parameters of vivid scene, this can be used to compare different light tracing the performance of the algorithm. For look very similar image, we also designed the method used to compare the quality of the images is similar to the difference.
