What are the potential problems with this multithreaded procedural generation algorithm?

I know this is game design related, but I have read the StackOverflow FAQ and it states software algorithm questions can be asked here. If this is better off in game design then I hope someone can help me move it, thanks! I am designing a…

How do I get rid of seams in my procedural asteroid generator?

I am coding a procedural asteroid generator in Unity using a custom mesh. The main idea is taken from this YouTube series, where you basically create your own cube with six evenly sub-divided sites, then normalize the vertices and apply a noise…

hash function for a set of 2d curves

I am looking for some spatial hashing algorithms that can hash a list of 2d curves (bezier splines) and have following properties: Tolerance: since control points are expressed in float3 (where z is always 0), I need some kind of threshold to…

Godot: Rendering Terrain In Separate Thread Slower Than Main Thread?

I'll admit, I'm new to multithreading and I was hoping to dabble in it with my C++ project first but I've hit a snag in my Godot game project where rendering the terrain gave me a small lag spike every time new terrain was generated so I wanted to…

What is the best approach to make procedural world generation in three.js?

I have the function CreateChunk(x,z) that creates a "chunk" of terrain in the specified coordinates x and z that is a plane, whose vertex heights are modified with Perlin noise and then painted based on their height (a layer of water is added too)…

How can I rotate a square to minimize the distance between each point and four arbitrary points?

I have been trying to follow this article: https://andersource.dev/2020/11/06/organic-grid.html Specifically, the appendix. But my understanding of calculus and its notation is limited. So I tried also to understand and adapt/rewrite the source…

How to create a Save / Load system for Unity Tilemaps?

I am making a game that procedurally generates a level and sets tiles via Tilemap.SetTile(). I've been reading and watching tutorials about saving in unity and from what I understand I need to serialize data so it can be saved in a binary file.…

How to fill out a procedurally generated mesh with quads of varying sizes?

I'm generating meshes based of color coded areas on an image. In the following picture, the semi-transparent image is a representation of what a color coded section might look like, with the black dots being natural 2d vertex…

Calulating The derivative of an fbm function and applying

I'm creating a 2D mesh based off of an fbm function in unity. I know a good thing to implement is using the derivative of the function to smooth the side of steeper mountains and hills accordingly for more realistic effects. My question is given my…

How can I take an algorithm that works very well in a 2D space and adapt it for 3D environments?

I liked the technique Spelunky used to generate the levels in the game, and I want to adapt it for a 3D space, so that I can use it to help me design something in that 3D space. I'm just not sure how to approach this kind of problem. I feel like a…
