Items are overlapped in some cases which provides incorrect results sometimes

Hi @dvdoug,

I loved the BoxPacker that you created and it seems to be working fine most of the times but in certain test cases I have observed that the items are not correctly stacked which results in inconsistent results.

I compared the results with the bin packer provided by - https://www.3dbinpacking.com which shows the 3D representation of packed items and below are the parameters that I used.

As you can see it packs the 18 items in a single medium box but when I try the same with BoxPacker implementation the items are packed in a medium (15 items) and a small box (3 items).

To further debug the issue I mapped the items from medium box into 3D cubes using threeJS and below are my findings -

As you can see some of the items are overlapping and not stacked correctly. You can check my implementation demo here - https://clarteresearch.com/projects/BoxSizeCalculator3D/

Here is the repo for the above demo - https://github.com/AdityaRawat96/BoxSizeCalculator

Thanks!

Hi @AdityaRawat96

I'll take a look, seems to be case of the first item being placed in a different orientation, and then everything else being a knock-on consequence of that.

Hopefully 🤞 this one should be fairly straightforward, as all items have the same dimensions so there's no issue around sorting, only placement

Did you had any suggestion here or fix? Having the same issue for us too..

Thanks
