→How does Signed Distance Field work?
To read the SDF version of image, we will need to use a custom shader that can understand the SDF version. With help of custom shaders, we can do many more effects such as edge glows, drop shadows, soft edges and etc. All these effects at virtually no additional rendering costs.
=== How to convert image to SDF version? ===
It turns out to convert a image to SDF, it is very computationally expensive. There are however, many methods that approximates and are relatively fast, but the Brute-Force method produces the most accurate result and it is the method that Valve used for their textures.
