This is a bin packing implementation based off of this fantastic paper. Originally developed as part of Part Placer for the woodworking community, however it can be used for all sorts of bin packing applications! Guillotine based algorithms translate well for many real-world material use cases, as they nicely balance outputs that can easily performed on machinery with efficient material use.
npm install guillotine-packerimport { packer } from 'guillotine-packer'
const result = packer({
binHeight: 30,
binWidth: 30,
items: [
{
name: 'test2',
width: 20,
height: 20
} as Item,
{
name: 'test',
width: 20,
height: 20
} as Item
]
})
/* OUTPUT:

*/| Property | Default | Description |
|---|---|---|
| binHeight | undefined | required Height of the bin we will be packing the items into |
| binWidth | undefined | required Width of the bin we will be packing the items into |
| items | undefined | required Array of items. Each item should have a width and height property. Additional properties will be included in the item property of the results |
| Option | Default | Description |
|---|---|---|
| kerfSize | 0 | The size of the blade kerf to account for when splitting rectanges |
| sortStrategy | undefined | SortStrategy to use. Undefined will try all strategies and pick which performs the best. |
| splitStrategy | undefined | SplitStrategy to use. Undefined will try all strategies and pick which performs the best. |
| selectionStrategy | undefined | SelectionStrategy to use. Undefined will try all strategies and pick which performs the best. |
| allowRotation | true | Whether items may be rotated. If true, items will be rotated if doing so maximizes the offcut size. |
