      如题,结果看起来是正确的,但是这个进度条都要10几分钟是怎么回事..有同学遇到吗

      应该是BVH做的不对,你这个速度比直接遍历所有三角面还慢

      说个题外话,我第一次渲染15min,然后结果啥都没有;后来发现BVH的逻辑写反了,把有交点的都忽略调了
      像这种耗时久的问题,建议debug的时候,只渲染一部分,比如图片中间的100*100的像素

      我想问下只要写完那几个函数就可以运行吗?因为我建树的过程是0,但是渲染要十几分钟,我不知道是不是哪里没有修改……

      我一开始比你还夸张,渲染了半个小时,后面发现是bounds范围写错了,你可以检查一下
