Let's start with the most interesting part of this chapter; the use of the built-in post-processes in Babylon.js. There are several post-processes that can beautify your scenes only though the use of the following elements:
- Volumetric light scattering: This shows how to easily scatter the light rays of a given light source, such as a sun or a moon.
- SSAO rendering pipeline: Screen-Space Ambient Occlusion. In other words, this rendering pipeline tends to approximate the ambient occlusion of a scene for more realism, only using a post-process.
- HDR rendering pipeline: High Dynamic Range rendering. This rendering pipeline is directly related to the lighting in the scene and tends to simulate the way retinas work in the real world.
