Ray-Marching

-
The Fluid Simulation I made earlier using render targets broke as I made a lot of changes to the water system since I first made the render target. However, before I attempt to fix this I thought it might be a good idea to try and integrate another type of fluid simulation I saw on Twitter by Campo Santo's Matt Wilde.






I was a little confused by what Signed Distance Field is and if it was related to the normal distance field I see in UE4. However, James Burton (White Paper Games) informed me that signed distance field are usually used in Ray Marching. He advised me to watch some Youtube videos on the subject.. He also mentioned that this was getting into Graphics programming territory. As much as I'd like to learn how this is made, I might have to leave this alone and attempt to fix the render target fluid simulation I'm trying to create.


I thought you might like this funny video of Pythagoras using Laptop as seen in Sebastian Lague's video on Ray Marching. The sound effect in his video makes it even funnier: https://youtu.be/Cp5WWtMoeKg?t=16

Environment Showcase Concepts

I thought it's about time to start working on creating the environment to showcase the water in the best way possible. It was suggested that I create this really cool Skull Waterfall environment concept art by Andrey Egorov: However, I will be using this concept as my initial inspiration and will be making my own iteration to the environment so it will not look exactly the same as the concept. It takes a bit of time figuring out and creating some of the features for the water shader. While I do this, I can work on creating the environment so I will be working on the water shader in small increments.

Distance Field water foam

Distance Field Foam Vectortoradialvalue, DistanceFieldGradient used for U channel and DistanceToNearestSurface used for V. I thought about how texture coordinates worked and how VectorToRadialValue worked. Both being gradients in R(U) and G(V), I had a theory about creating coordinates based on using Distancetonearestsurface node as G(V) channel and have VectorToRadialValue or Distancefieldgradient node as the R(U) channel. I was initially going to use the DistanceFieldGradient node that I learned about when making the distance field flow map. This is because the node had that Texture coordinate look to it but it adds a lot to the shader instructions so I went with VectorToRadialValue node. I extracted and used maths for the R channel from VectorToRadialValue and it produced the coordinates I wanted. I then added this coordinate to the noise based foam I made earlier using Alex Vinogradov's approach. I later decided to add Distancefieldgradient node just to see if it pro

World alignment (Tri-planar mapping)

From reading the UE4 documentation, I found out that material functions are a bunch of nodes packed into one node. I figured out the Math behind how world alignment works by deconstructing and experimenting with the World Aligned Texture node. This node is one example of a material function. It is also widely known as Tri-planar mapping in substance painter. Material Function for Tri-planar mapping  This gave me the idea to make a block out material which can have grids, scale without texture stretching and change colours the way I want it to. I also wanted to add the functionality of animating the material. I did this by making some modifications to the World Aligned Texture material function. Modified Material function with comments to help understand which part is doing what. I found that substracting the WorldPosition from the Object Position will force the material to move along with the object and not have a weird scrolling effect whenever you move the object.
