The Art of Procedural Noise
Hi! I’ve created a video about procedural noise that focuses on the relationship between noise and nature, the theory behind noise, and many other exciting topics that go beneath the surface. I hope it will give you a new fresh perspective on noise!

A random generator for videogame mechanics
As the title says, I've created a quick and dirty combinator of video game mechanics, it's crude and ugly, put if the community has interest on it, it will be expanded.

Building Room Generator Algorithm
I'm looking for a room generator algorithm for use in the basement areas of my procedural buildings. Something sort of maze-like where it's easy for the player to get lost. I guess it's "backrooms" style. However, the requirements are somewhat different from many of the dungeon generators I see here in this sub.
1. Not (necessarily) grid based. These room networks are huge with thin walls, so it's not practical to create a grid where the walls and objects fit inside grid cells. And connect to other doors, stairs, etc. that aren't aligned to a grid.
2. Maze-like, but not a perfect maze. There can and should be loops, ideally with some way to control their frequency.
3. The rooms fill a rectangular area with no or few gaps/empty regions. I'm looking for something that subdivides an input rectangle rather than creating rooms randomly in space.
4. All areas are reachable. Well, this may be too strong. I at least want a guarantee that a path exists between all entrance doors and most of the area is reachable as well. But it may be okay to remove walls to connect rooms as a postprocessing step.
5. Must be fast. These regions are generated on the fly as the player explores, so let's say 16ms max for subdividing the rectangle. This rules out algorithms with exponential runtime, backtracking, things like WFC, etc.
6. I'm looking for an algorithm that I can implement in C++ for a custom game engine. Not a plugin for an existing game engine or pre-built library.
So far the best I've come up with is placing walls of random position and length in either X or Y with constraints that no two walls can be less than a player diameter apart without touching (so no small gaps). Then I do a Boolean NOT of the walls expanded by the player radius to get the walkable area. I determine the connected components of the graph. Then I remove sections of walls that divide two disconnected components iteratively until all walkable areas are connected. This works and is relatively fast, but doesn't give much control over the number of loops, open areas, rooms vs. hallways, etc. Some results are acceptable, while others are not. For reference, the code I currently have is in the function building_t::add_backrooms_objs() here:

Any suggestions for alternate algorithms or improvements to what I have would be appreciated.

Guides on how to make procedural houses
What guides would you suggest on making procedural houses / towns / castles / villages? I want to incorporate procedural houses into my game with the procedural terrain but im not sure how to go about doing it. My main curiosity is how do i align the houses with the rise and fall of the terrains noise? Im making my game in unity.

Small Game Group looking for experience on Procedural Generation
Hi,
I have a small game group that is working on an open world multiplayer game, with a strong focus in open world, biome implementation, and meta mapping. We have a few guys fluent in C#, and some unity experience, but I would like to see if anyone would be around for possible project experience, or just general mentorship.
Thank you for reading, enjoy yourselves, I love seeing what this community makes :)

Procedural Road Generation
I am attempting to procedurally generate a road-surface mesh using B-splines. Currently, I am generating a B-spline from control points and applying an offset to those points to create the width of the road by calculating normal/tangent/bitangent vectors at interpolated spline vertices. The attached image is the result I'm getting (2d points for simplicity's sake). The inside corners of the road in the image show the issue with my implementation, but I'm not sure how to avoid this issue.
Is there a better solution I'm missing? Or is there a way to avoid the artifacts being created at the corners?
EDIT: Image didn't stick.

Various Unity noise libraries performance comparison
I've been doing a lot of benchmarking lately to try to optimize some of my heavier code, so I figured I'd post the results here in case others are curious.
​
# 2d Gradient Noise - 256x256
|Library|Computation Time|Uniformity|
|:-|:-|:-|
|FastNoiseLite Perlin|\~29 ms|Low|
|FastNoiseLite Simplex|\~28 ms|High|
|FastNoiseLite SimplexS2|\~29 ms|Moderate|
|Perlin Library|\~15 ms|Low|
|Mathf.PerlinNoise|\~16 ms|Moderate|
|Unity.mathematics Perlin|\~160 ms|Moderate|
|Unity.mathematics Simplex|\~140 ms|High|
It's important to note that Unity.mathematics was intended to be used with the burst compiler, so these results don't necessarily match it's optimal use.
​
# 3d Gradient Noise - 100x250x100
Run in a burst compiled, multithreaded job
|Library|Computation Time|
|:-|:-|
|Perlin Library|\~28.5 ms|
|Unity.mathematics Perlin|\~62.2 ms|
|Unity.mathematics Simplex|\~68 ms|
Interestingly, the Perlin library (which is almost a decade old at this point) seems to be 2x as fast as the newer, more highly optimized Unity.mathematics library. If anyone has an explanation I'm very curious as to why that is.
