Using advanced effects
The effects we are going to look at in this section don't differ a lot from the previous ones; they are just a little bit trickier and you will need some background knowledge to use them. So, let's dive into them!
In this section, we are going to look at the high dynamic range (HDR) and depth map advanced effect concepts.
Advanced effects
Let's start by discussing some requirements for some of these effects to work properly.
HDR and Depth maps
Some effects don't just work with the rendered image – they also need additional data. First, we will discuss depth maps, a concept we discussed in the previous chapter. To recap, a depth map is an image that's 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 farther from the camera the pixel is, and vice versa. In...
