Is ambient occlusion needed?
You would want to use ambient occlusion because it shows subtle variations in lighting and helps your eyes detect surface details that would otherwise be washed out or unnoticeable. Ambient occlusion is great for softening the overall lighting in your scene if it’s too bright.
Is ambient occlusion expensive?
Screen Space Ambient Occlusion is a post processing effect using the depth buffer to approximate the effects produced by Ambient Occlusion. Ambient Occlusion is a relatively expensive global method, while Screen Space Ambient Occlusion is the cheaper alternative for real time animation.
What are the different types of ambient occlusion?
There are a slew of different types and tweaked versions of true ambient occlusion. The main ones are SSAO, HBAO, HDAO and VXAO. What does SSAO mean? It stands for ‘screen space ambient occlusion’. It is a great alternative to normal ambient occlusion, especially for games with lower visual settings.
What does screen space ambient occlusion stand for?
It stands for ‘screen space ambient occlusion’. It is a great alternative to normal ambient occlusion, especially for games with lower visual settings. Instead of using shapes to determine the space between lighting, screen space ambient occlusion utilizes sleight of hand, specifically pixel depth to give the impression of lighting changes.
Which is better, ambient occlusion or SSAO?
If your game is simpler than Crysis, (and it probably is), SSAO is a totally viable and smoother counterpart to normal, full-fledged ambient occlusion. Of course, the drawback of using SSAO is that you aren’t exactly getting the entire graphical power that you would normally get.
How does ambient occlusion work in a game?
Aspects of a level where you would not see light normally will appear darker than those aspects of a level in which light is touching. An ambient occlusion is a trusty tool in which game developers and designers shade a scene and set up lighting to be as realistic as possible.
