What is occlusion in design?

In 3D computer graphics, modeling, and animation, ambient occlusion is a shading and rendering technique used to calculate how exposed each point in a scene is to ambient lighting.

What is occlusion layer?

Occlusion is a technique for calculating the shading of surfaces based on how occluded they are. Depending on the settings, any receding or recessed areas are shaded darker (or lighter).

What is ambient in 3D?

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 an occlusion shadow?

The crevasse shadow (also known as the occlusion shadow) is the part of the sphere just above where it touches the ground. Light can’t bounce it’s ways back up into this part of the form. For this reason, the crevasse shadow will be the darkest part of your shadow.

What is ambient occlusion?

Ambient occlusion is a scalar value recorded at every surface point indicating the average amount of self-occlusion occurring at the point on the surface. It measures the extent to which a location on the surface is obscured from surrounding light sources.

Does ambient occlusion make a difference?

HDAO or High Definition Ambient Occlusion is a similar technique, though it’s meant for AMD graphics cards to compete with NVIDIA’s HBAO. There’s no real difference between HBAO and HDAO, except that they’re native to their respective distributer’s GPUs.

Does ambient occlusion affect FPS?

Ambient Occlusion will have a noticeable impact on your FPS when you change its value from OFF to SSAO. However, as you increase it to HBAO+ and higher, the difference in terms of performance is insignificant (1 or 2 FPS reduction) while you get a decent visual improvement in return.

What is ambient occlusion HBAO vs SSAO?

We now know what SSAO stands for, but what is HBAO? HBAO stands for ‘horizon based ambient occlusion’. It is a step up graphically from the simpler screen space ambient occlusion. It ups the ante from every aspect in SSAO, giving the game better and higher definition, and visibility.

Which ambient occlusion is best?

HDAO is more subtle than SSAO and HBAO. It’s probably the most accurate, because there’s much less incorrect darkening. Choosing HDAO over SSAO or HBAO results in a small framerate drop on AMD cards, and a significant one on Nvidia cards.

What is an ambient occlusion map used for?

The occlusion map is used to provide information about which areas of the model should receive high or low indirect lighting. Indirect lighting comes from ambient lighting and reflections, so steep concave parts of your model like a crack or a fold would not realistically receive much indirect light.

How does an ambient occlusion map work?

An Ambient Occlusion or AO map is a grayscale map which contains lighting data. It is not typically used as its own map, and is instead usually combined with the diffuse map to bake in soft shadows.

When were ambient occlusion invented?

Ambient occlusion was first introduced by Crytek in 2007 with their creation of Crysis.

What are the 6 types of light and shadow?

Artists refer to six basic concepts when describing the behavior of light on a form, listed here in order of brightness: highlight, direct light, reflected light, shadow, core shadow and cast shadow.

What is ambient occlusion VRAY?

Ambient occlusion is a simplified way of using Vray dirt in the scene. The first scene did not use ambient occlusion. The walls are too bright, while the joints and the ceiling’s corners aren’t that well defined. There are also a lot of overblown highlights in the scene.

What is ambient lighting?

By definition, the term “ambient lighting” is also used to refer to general lighting. Ambient lighting dominates the lighting landscape of any space. This lighting category generally includes the main lights that you utilize to illuminate the entire area. Ambient light also has a way of setting the mood in a room.
