What is Horizon based ambient occlusion?

HBAO & HDAO HBAO stands for ‘horizon based ambient occlusion’. It is a step up graphically from the simpler screen space ambient occlusion. At first, I thought that HBAO was simply a step up from SSAO.

What should my ambient occlusion be?

This means HBAO, HBAO+ or VXAO on Nvidia graphics cards and HDAO on AMD cards. If none of the above are supported or if there are GPU compatibility issues, then SSAO is always a good choice. It will produce a very immersive environment and with a minimal performance impact.

Should I enable ambient occlusion?

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.

What is ambient occlusion quality?

Ambient occlusion is a technique used in production to approximate the effect of environment lighting. Unlike the dull, flat look of local lighting models, ambient occlusion can add realism to a scene by accentuating small surface details and adding soft shadows.

What does ambient occlusion?

15.14. 3 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.

Is ambient occlusion real?

Ambient Occlusion is a term which is used in computer graphics. However, there is no ambient occlusion in the real world. It is a rendering technique in the world of graphics that can duplicate the shading of light on an object in the real world. This method is implemented in real-time games, animation fields etc.

When to use Horizon based ambient occlusion ( HBAO )?

Horizon Based Ambient Occlusion (HBAO) is a post processing image effect to use in order to add realism to your scenes. It helps accentuating small surface details and reproduce light attenuation due to occlusion.

Is there such a thing as ambient occlusion?

VXAO, or Voxel Ambient Occlusion, is the closest video games can get to reality in terms of lighting and shadow rendering. However, not many games boast this setting, mainly because it’s too tasking and will push the limits of your processor and graphics card.

What are the settings for ambient occlusion in Crysis?

Some of the most commonly found settings include SSAO, HBAO, HDAO and VXAO. SSAO or Screen-Space Ambient Occlusion was the type of occlusion introduced by Crytek in their debut of Crysis. However, to save the processing power, SSAO doesn’t consider the space and elements that produce shadows.
