New blog post: "Please Steal My Meshing Algorithm Idea" This is something that I've been pitching to folks in person, but wanted to open it up to people that haven't met me at a graphics conference recently

It does not seem directly relevant but since you’re a modeling nerd I thought I would pass along this neat paper I’ve been using to build my CAD kernel. It’s BREP not implicit but perhaps thought provoking. bsky.app/profile/sequ...

Thanks! Ya the kernel is still very early but it is an implementation of this paper which offers a simpler method of performing booleans than more common approaches, which makes it tractable. Claude did all the heavy lifting, which is also what makes this tractable. dl.acm.org/doi/abs/10.1...

Ah yes, "We have simplified BREP intersection by reducing it to mesh intersection", a famously easy problem 😛 (this looks great, thanks for sharing it)

Have you seen the m-rep niche of b-rep research, e.g. www.mattkeeter.com/projects/mrep/? I have a vague feeling that there's a robust BREP kernel hiding somewhere in there, but it's hard to surmount the Wall Of Math

I haven’t seen that! I’ll take a look. And yeah, I had to find some sort of simplified b-rep Boolean architecture to make my project even remotely tractable. I still don’t have every case in my 300 case test set functional but we’re making great progress. Curious to find where the method fails.
