闭塞动作

Question

I just started learning opengl and writing a first person shooter but I'm getting horrible framerates when I draw 5000 cubes. So now I'm attempting to perform occlusion and culling using an octree. What I'm confused about is where to cast the rays from. Do I only cast them from the fustrum near plane? It seems like I would miss part of the fustrum that expands.任何帮助都将受到赞赏。

Answer 1

如果5000立方体已经给出了不良的帧速率，则应考虑更改渲染立方体的方式。

我想提供更多帮助，但我不确定您在做什么。
