These function are extremely powerful to achieve amazing results in graphics. They can be used for Signed Distance Fields, Landscape Height Blending and much more stuff.
They come handy every time you want to pass through the highest or lowest value, but also blend them together to not have a sharp seam.
My explanation is done in Desmos and the implementation un Unreal Engine 4, but as always this stuff is perfectly valid for UE4, UE5, Unity, Godot, etc ;)
You can see this videos for a practical use case:

In this video we go through a simple implementation and use case sample of ray casting applied to material shaders.
It is done in Unreal Engine 5, but can be applied everywhere (UE4, Unity, Godot, Shadertoy and whatnot, your choice).
At the same time we also look at some more ways to make a plane billboard, as a followup of my previous video on that topic.
The shader will be available for my supporters on Patreon.

Grab the interpolated CellNoise function here: https://jumpeter.gumroad.com/l/VTA_InterpolatedCellNoise
This video explores the technical aspects of shaders and graphics in Unreal Engine 5, but these concepts are valid in any game engine that uses textures (all of them :D).
The focus is on the topic of filtering, specifically the differences between bilinear and bicubic filtering. The underlying mathematical concepts of bilinear filtering are discussed, as well as how it is used to smooth out textures.
Than we explore the concept of bicubic filtering and how it takes this technique to the next level.
The code behind these filters is analyzed, and a demonstration is provided on how to implement them in Unreal Engine 5 projects.
This tutorial provides valuable insights on how to connect art, math, and code, and viewers will gain a deep understanding of bilinear and bicubic filtering and how to use them to enhance video game graphics.

In this video we dive into the new shader pipeline that was revealed by Epic in Unreal Engine 5.2, Substrate!
We try to analyze everything as best as we can and make our own conclusion about how a new generation material pipeline might work.

In this video we go through a correct implementation of the triplanar projection mapping technique for world mapping textures in our shaders.
We discuss its properties, advantages and shortcomings. Then we build on that to create some new and better tech to fit it on the landscape material.
