rust-rectangle-dividing

A library of rectangle dividing written in Rust.
It can be compiled to WebAssembly. So you can use it in JavaScript.

Motivation

I want to divide a rectangle into smaller rectangles by given conditions (weights, aspect ratio, etc.).

Mainly, I want to use this for generating a map for my react-playground
- https://github.com/kitsuyui/react-playground
- https://react-playground.docs.kitsuyui.com/storybook/?path=/docs/base-treemap-introduction--docs

Usage in JavaScript

$3

This package is published on NPM @kitsuyui/rectangle-dividing

``sh
$ npm install @kitsuyui/rectangle-dividing


or

$ yarn add @kitsuyui/rectangle-dividing

or

$ pnpm add @kitsuyui/rectangle-dividing
`

$3

`js
import { dividing } from "@kitsuyui/rectangle-dividing";

const rect = { x: 0, y: 0, w: 900, h: 800 };
const weights: Float32Array = Float32Array.from([4, 4, 1, 1, 1, 1]);
const aspectRatio = 1.5;
const verticalFirst = true;
const boustrophedron = true;
const divided = dividing(rect, weights, aspectRatio, verticalFirst, boustrophedron);
for (const d of divided) {
console.log(d);
}
`

$3

`js
{ x: 0, y: 0, w: 600, h: 400 }
{ x: 0, y: 400, w: 600, h: 400 }
{ x: 600, y: 600, w: 300, h: 200 }
{ x: 600, y: 400, w: 300, h: 200 }
{ x: 600, y: 200, w: 300, h: 200 }
{ x: 600, y: 0, w: 300, h: 200 }
`

dividing's arguments are

- rect: The rectangle to be divided
- weights: The weights of each rectangle
- isVertical: The direction of the first division
- aspectRatio: The aspect ratio of each rectangle
- boustrophedon`: The direction of the next division in the same level
