I have been working on a procgen dungeon maker and I have no idea what I am doing.
I am not exactly sure what I am doing wrong. Wvwry time I think I am getting close, my logic in the code just goes bonkers. It always overlaps no matter what I do! The rooms always overlap each other. I'm aware this is a learning curve kind of thing. Does anyone have a good tutorial/guide for the coding algorithm needed for procgen to work with room prefabs and specific door locations per room?

more voronoi trouble...why are some cell walls not extending to their circumcenter?
if you have seen some of my other posts, you know i am working on developing a voronoi based city using threejs. I am taking a different approach now, utilizing the [delaunator npm package](https://github.com/mapbox/delaunator) to detect circumcenters, and then connect them to form the cell walls.
i have spent all day trying to figure out why some of these walls are not reaching their end points (see image below)

here is my script. any ideas what is causing this problem? thank you
import Delaunator from "delaunator";
import * as THREE from "three";
import { _math } from "../_/math";
export const getVertexData = (x: number, y: number) => {
const gridSize = 100; //500?
const roadWidth = 5;
const currentGrid = [Math.floor(x / gridSize), Math.floor(y / gridSize)];
var points = [];
for (let ix = currentGrid[0] - 1; ix <= currentGrid[0] + 1; ix++) {
for (let iy = currentGrid[1] - 1; iy <= currentGrid[1] + 1; iy++) {
var pointX = _math.seed_rand(ix + "X" + iy);
var pointY = _math.seed_rand(ix + "Y" + iy);
var point = new THREE.Vector3(
(ix + pointX) * gridSize,
(iy + pointY) * gridSize,
0
);
points.push(point);
}
}
var currentVertex = new THREE.Vector3(x, y, 0);
const delaunay = Delaunator.from(points.map((point) => [point.x, point.y]));
const circumcenters = [];
for (let i = 0; i < delaunay.triangles.length; i += 3) {
const a = points[delaunay.triangles[i]];
const b = points[delaunay.triangles[i + 1]];
const c = points[delaunay.triangles[i + 2]];
const ad = a.x * a.x + a.y * a.y;
const bd = b.x * b.x + b.y * b.y;
const cd = c.x * c.x + c.y * c.y;
const D = 2 * (a.x * (b.y - c.y) + b.x * (c.y - a.y) + c.x * (a.y - b.y));
const circumcenter = new THREE.Vector3(
(1 / D) * (ad * (b.y - c.y) + bd * (c.y - a.y) + cd * (a.y - b.y)),
(1 / D) * (ad * (c.x - b.x) + bd * (a.x - c.x) + cd * (b.x - a.x)),
0
);
circumcenters.push(circumcenter);
}
const voronoiWalls = [];
for (let i = 0; i < delaunay.halfedges.length; i++) {
const edge = delaunay.halfedges[i];
if (edge !== -1) {
const v1 = circumcenters[Math.floor(i / 3)];
const v2 = circumcenters[Math.floor(edge / 3)];
if (v1 && v2) voronoiWalls.push(new THREE.Line3(v1, v2));
}
}
for (let i = 0; i < voronoiWalls.length; i++) {
var closestPoint = new THREE.Vector3(0, 0, 0);
voronoiWalls[i].closestPointToPoint(currentVertex, true, closestPoint);
if (currentVertex.distanceTo(closestPoint) <= roadWidth) return "road";
}
return "block";
};
Edit: i have confirmed that the circumcenters are in the correct spots. i think this may have something to do with the voronoiWall calculations...having a bit of trouble understanding the delaunator plugin. Here are the docs i've been trying to follow: [https://mapbox.github.io/delaunator/#incoming-edge-index](https://mapbox.github.io/delaunator/#incoming-edge-index)

What algorithm would work best for rigid stepped elevations, while having smooth portions.
Wow, that's a long title! But it basically describes exactly what I'm looking for. I had previously been using fractal noise with octaves in order to create terrain, and this worked very well for things such as large "relatively smooth / flat" areas of land mass.
However I am wondering what algorithm would work best to incorporate rocky formations or ridges on top of these smooth portions. Sort of like a step elevation.
Below are a few pictures which represent what I'm attempting to achieve. Thanks for your time! :)

Ridges and a sort of \\"step\\" elevation
Rocky Formations, etc...

Games with a lot of procedural content
Hi! Is any games that generates a lot of content procedurally? Not only map or dungeons. I mean random/procedural NPCs, divines, mythology, lore, quests, races, etc.
I know, Dwarf Fortress and Wizards and Warlords can do some of that.

How could you create very abstract and ever-changing terrain?
I've been experimenting with procedurally generated terrain in Roblox, specifically with modifying 3D Perlin noise. While I've managed to create a variety of terrains, from abstract to realistic, I'm facing a challenge.
The issue is that the generated terrain tends to look quite similar across the map due to the inherent characteristics of Perlin noise. I'm on a quest to achieve something more extraordinary – a terrain that becomes increasingly bizarre and otherworldly the further you travel, almost like stepping into another dimension. Something that always looks different and unique.
Is it simply a matter of adding more noise layers, with varying levels of amplitude and frequency, or are there other methods to break away from the Perlin noise predictability and achieve that mind-bending, alien, or and almost inter dimensional effect?

Need ideas for my dissertation project please
Ok first of all I am a complete newbie with procedural generation. Please treat me like one. I was just very fascinated with the whole idea of procedurally generating stuff. I have played No Man's Sky and the whole concept just blew my mind. And I really want to try it myself.
So to the main point. I need help for ideas about my dissertation project. In general, we are supposed to base our project on a pre-existing paper published by someone else and maybe try to find improvements in it. I have around 2 Months to do the project and learn the stuff. I very much want to do something with ML and PCG. I personally want to do something original using methods that have not been researched upon a lot and hopefully achieve positive results that show that the method I used is better than the ones that other papers mention.
So any and all ideas are appreciated please! _/\\_
As for my knowledge level, I am a computer science master's student and I created a project where I trained a model that predicts the guitar chords using CNN in real time. So I have some knowledge in Machine Learning and Neural Networks.

Can we consider AI-assisted game designing as a part of PCG?
I am currently working on a review paper related to Procedural Content Generation. When I was reading research papers, I came up with AI-assisted game design as a different topic from the PCG. The term PCG refers to using algorithms to create content, either semi-automatically or automatically. AI-assisted game design also aids designers in creating game content such as levels, items, and so on. So, can it also be considered a component of PCG, especially since there is a sub-field of PCG called mixed-initiative/Co-creation?
Please note that I'm a beginner in this field.
