Gerstner Wave Livestream

-
I was watching the Gerstner Wave Livestream but there a few things that are worth noting down but I forgot what they were. So I went through it again and at the same time I created the material and made Notes.



Here are the notes made:

  • Mentions that Wavelength (L) and Speed (S) could be related to each other based on physics/gravity? livestream vaguely mentions this. Might be worth looking into. Time: 41:50
  • Some people divide the Gerstner Waves by the number of Gerstner Waves used for a nicer result. Time:51:30
  • Uses Screen Space Normals which is expensive. Requires turning off tangent space in details panel of the material to set it to world space. Time:52:20
  • Says there is a way to do Tangent Space Normal (Cheaper) but does not cover this using Cosine but he sticks to Screen Space Normal. Time:53:40
  • This is not related to the Gerstner Wave but mentions "Texture Bombing" to break up tiling. Might be still worth learning about for general purposes. Time1:05:10
  • Mentions a way to control Steepness (Q) based on the Amplitude (A). Time: 1:42:40
There's a lot of interesting things that could be added. I'm particularly very interested in creating the Tangent Space Normals and Texture Bombing. Although texture bombing is off-topic from the Gerstner wave, it might be really useful for material creation in general. Especially for breaking up the repeating patterns of the texture. As for other features such as linking parameters together, those may or may not be added depending on the time I have.

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.
