So what is SSAO and HBAO? Well, let’s answer that with a look at the different types of ambient occlusion and how they’re used in your favorite titles. SSAO SSAO refers to screen space ambient occlusion. It was the first technology to render 3D lighting in real time, and it makes ...
With the help of geometry,it’s much more effective at rendering shadows and lighting. The major disadvantage of HBAO is that, unlike SSAO,it requires more computational power in both the CPU and GPU. Later, HBAO+ was introduced to provide a less performance-tasking algorithm for light and s...
