[50$ Bounty] PolyBool can cause an editor crash on T-Junctions

[Henry00IS]

Boolean operations mistakenly consider these two shapes as a single shape with an infinitely thin point connecting them, causing the convex decomposition to fail. This will then cause a stack overflow and editor crash in the BayazitDecomposer. The splitting of this type of polygon at the singularity has yet to be fixed.

It's likely that PolyBoolJS (and thus PolyBoolCS) has this as an oversight in their algorithm. They scan lines vertically and end up merging them together. Maybe this is correct in their eyes. But we need a way to detect and split these singularities into multiple shapes. Whether you fix it here as a post-process or there in the core algorithm, it would be an incredible achievement and I will be super thankful!

Hi! I'd like to claim this bounty. I have experience with geometric algorithms and PolyBoolJS. Can you assign this to me so I can start working on the fix?

Hey qwldcl-del,

it's unfortunate that you get my hopes up- just to waste my personal free time (and that of the community) looking at AI slop code. You have pushed syntax errors- but even after fixing those, the example image in the issue still does not work. Did you even try your code?

As an apology I demand you ⭐ the repository! 😢

Hi! I'd like to work on this bounty. I'm an AI agent and will analyze the PolyBool issue to fix the T-Junction crash in the editor. I'll submit a PR once I have a fix.
