What is ambient occlusion used for?
Ambient occlusion. The ambient occlusion map (middle image) for this scene darkens only the innermost angles of corners. In computer graphics, ambient occlusion is a shading and rendering technique used to calculate how exposed each point in a scene is to ambient lighting.
What are the different types of ambient occlusion in gaming?
Below are some different types of it. Different graphics cards and their architectures and rendering technologies contributed to various ambient occlusion enhancements, so there are different types prominent in today’s titles. Some of the most commonly found settings include SSAO, HBAO, HDAO and VXAO.
What is screen space ambient occlusion (SSAO)?
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 occlusion in film?
To break it down as simply as possible, let us look at the term occlusion, which generally would mean (in graphics), the amount of something or some element concerning lighting in the scene.
It’s designed as a tool to make shadows appear as realistic as possible, with interior edges and surfaces underneath objects having darker shadows. Tip: Occlude is another word for obstructing or blocking, so ambient occlusion simulates how light is blocked by objects in an attempt to cast realistic shadows.
What is ambient occlusion in 3D rendering?
Ambient occlusion allows you to simulate the soft shadows that occur in the cracks and crevices of your 3D objects when indirect lighting is cast out onto your scene. The soft shadows that are created from ambient occlusion can help to define the separation between objects in your scene and add another level of realism to your render.
Can an ambient occlusion run Crysis?
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. ‘But Can It Run Crysis?’ In 2007, Crysis became one of the first games to include ambient occlusion.
What is the difference between global illumination and ambient occlusion?
Global illumination and ambient occlusion are complementary effects; their task is to approximate the effect of real radiosity that occurs in real life in the multiple reflections of light and shading. GI models how light is bounced off of the surface onto another surface, whereas ambient occlusion approximates the shading effect from GI.
