What is occlusion computer graphics?

In graphics, ambient occlusion is a shadowing technique used to make 3D objects look more realistic by simulating the soft shadows that should naturally occur when indirect or ambient lighting is cast out onto your scene.

What is occlusion in gaming?

In graphics, ambient occlusion is simply the point at which an object stops light from a source, as well as the point in which an object throws light or shadow in its created world. It is what adds depth to a scene in a video game like Crysis or a movie like Pixar’s Monsters University.

Does ambient occlusion affect FPS?

And additionally, there seems to be a significant drop in performance – sometimes the difference between 60 and 45 FPS – if I use the different types of AO.

What is occlusion texture?

Occlusion texture maps are normally calculated by 3D applications directly from the 3D model using the modeller or third party software. An occlusion map is a greyscale image, with white indicating areas that should receive full indirect lighting, and black indicating no indirect lighting.

Is ambient occlusion CPU or GPU?

SSAO does not use any CPU to work, which provides the gamer with a solid amount of visual eye candy for 1/4th of the output.

Is SSAO good for games?

Screen space ambient occlusion is a great method in which to develop certain games, and especially great when running a game on perhaps an older PC, or one with low CPU power. SSAO does not use any CPU to work, which provides the gamer with a solid amount of visual eye candy for 1/4th of the output.

What is ambient occlusion art?

Ambient occlusion (AO) is best described as the soft, subtle shadowing that appears between close objects and other tight spaces where light can’t easily reach. When emphasized in the painting process, AO gives art a very distinct look — almost like a computer-generated 3D model.

What causes occlusion?

Most occlusions are caused by either a blood clot or the buildup of fatty plaque in the arteries (atherosclerosis). A blood clot can form at the site of occlusion, or it can travel from another area through the bloodstream and block an artery. That runaway clot is called an embolism.

What is an optical occlusion?

An eye occlusion is a blockage in one of the arteries or veins supplying blood to the retina and/or optic nerve. These blockages can cause severe and sudden vision loss.

What is SSAO type?

The most common type of ambient occlusion is SSAO or screen-space ambient occlusion. It is the least demanding out of all kinds of ambient occlusion, although the actual quality of the effect can vary greatly from game to game based on how well the developers implemented it.
