Culling is an important part of modern graphics, you definitely don't want anything you aren't looking at wasting

valuable resources.

Now wait... what's the purpose of doing it ourselves? I think I read somewhere that GPUs will cull

objects itself, and won't try to rasterize them...

## Theory
|
|
|
|
|
|
|
|
|
|
So let's go over that naive approach, and how it doesn't work. Let's take this scene
|
|
|
|
|
with a lot of McGuire models, which if you don't know are stupidly high poly so thse are perfect for testing.
|
|
|
|
|
|
|
|
|
|
If you remember, GPUs will check if your triangles are even in the viewport, and will
|
|
|
|
|
dynamically cull them and prevent them from rasterizing - right?
