I've quietly made my LayerProcGen framework public:
https://github.com/runevision/LayerProcGen

It's a framework (C#) that can be used to implement layer-based procedural generation that's infinite, deterministic and contextual.

Nobody else have tried/tested it yet - if you're up for taking it for a spin, let me know how it looks; what's clear or confusing, if you think there's low hanging fruit improvements I could make, etc.

@runevision I got a job offer and ran out of time, so I focused on implementing the functional terrain. Your implementation is much better fleshed out than mine would have been.

My idea was similar to yours in that coarse levels would place towns and the paths between them which would influence the terrain generation of the finer levels they overlap. Likewise, I intended to generate watersheds that would force the land to descend as needed.

Your implementation easily subsumes mine.

@runevision For my PhD thesis, I created a multi-layered grid generating / caching system that you could think of as the dual of a quad-tree with the grid coordinates on the odd values rather than the evens. No two LODs share the same boundary which let me amortize updates across the different levels as you move. Also, objects of any scale would be fully contained in a single cell of some detail level. I didn't get around to implementing anything using the latter.

Flock by hue

Particles are most strongly attracted to the hue just ahead of them on the color wheel and flee the ones opposite.

- Flocking

4000 particles swarm around each other creating temporary rainbow flows that break and reform as they crash into each other.

scdollins,
@scdollins@genart.social avatar

@qurlyjoe Yes. After the initial random start, it's purely deterministic, so the same initial conditions should always lead to the same animation.

The frustrating aspect to simulations is that there is no closed loop unless you do some rather contrived forcing to move particles back to their start positions.

3D Flock by hue

- Flocking

4000 particles swarm around within a sphere forming rainbow flows that break and reform as they pass near each other.

@TodePond Sorry to interrupt, but a Brit vector is any mechanism for spreading British memes, e.g. Monty Python or Douglas Adams quotes. Or todepond videos.

Looping flock

Coherent noise yields a coherent flock

- Flocking

Multi-colored worm-like particles swarm around in flock-like behavior within a sphere

scdollins,
@scdollins@genart.social avatar

@tschundler Right. Their behavior is only coherent because the underlying noise function is coherent. I just add a looping noise value to their start position and scale it back down into a sphere.

A Spiral of Cetaceans in a Swirling Sea

#CreativeCoding #AlgorithmicArt #Processing #Maze

looping animation of waves of light fading to dark sweeping through a radially symmetric circular maze with multiple smooth paths spiraling out separated by swirling paths spiraling inward

scdollins,
@scdollins@genart.social avatar

@txo_elurmaluta It's a maze where the paths have a bias to follow a polar graph of a multi-armed spiral. The animation colors each segment of the maze based on its distance to the starting point with a shifting phase.

It uses buffer-less rendering of 100,000 screen-aligned triangles textured with spheres. Each one is sized, colored, and animated entirely within the vertex shader.

This is basically the same code as my flocking algorithms, but looks cooler. 12,000 particles "flock" to be near their loop neighbors while avoiding other collisions.

scdollins,
@scdollins@genart.social avatar

@bit101 For a random point in a ball, you want to multiply the radius by the cube root of a random, not the square root.

You can use sqrt of the radius to generate points in a 2D disc.
