Using advanced effects
The effects we are going to see in this section don't differ a lot from the previous ones; they are just a little bit trickier and need some background to properly use them. So, let's dive into them!
In this section, we are going to see the advanced effect concepts of
High Dynamic Range (HDR) and Depth Maps.
Advanced effects
Let's start by discussing some requirements for some of these effects to work properly.
HDR and Depth Map
Some effects not only work with the rendered image but also need additional data. We can first discuss the Depth Map, a concept we already discussed in the previous chapter. To do a recap, a Depth Map is an image rendered from the point of view of the camera, but instead of generating a final image of the scene, it renders the scene objects' depth, rendering the objects in shades of gray. The darker the color, the further from the camera the pixel is, and vice versa. In the following screenshot, you...
