The occlusion planes are used for occlusion culling and not the bounding boxes themselves. These just represent the possible area that is occluded by an occlusion plane.

Got here by googling Occlusion Cullion after reading Notch tweet it. PUPPY BWAIN CAN'T COMPWEHEND!

@chrisdoney Did Notch tweet it?

Using a bounding box to calculate occlusion surfaces may seem fine, but what happens when models, such as donuts, have holes in them ? The bounding box will still encompas the entire object, including the hole, which will cause the occlusion culling to not render items seen through the hole of the donut.

Thank you for the explication, good sir. :)

Is this song from Oblivion?

@AquarianPython The reason you'll need a semi-decent GPU is that your PC has to calculate what is and isn't in view to determine what to process and what to not. So faster computers utilising OC perform even FASTER, whilst slower computers are still slow and won't benefit from this.

@AquarianPython Basically, if you can't see something in the game - it won't be rendered. Thus your computer doesn't have to process it at that point in time meaning performance from said game.

For example, if you are in your mine-shaft, you can't see the surface of the map and your housing etc., so why waste resources processing it? You'll likely gain an FPS boost as a result.

@AquarianPython me too!

@Skateronastick im sorry but im a total idiot in this. can you use simple words? lol

[Skateronastick]

@tingyuyan12 It's basically texture streaming but it hides everything you are not looking at instead of just the textures

[tingyuyan12]

i dont get it?
