[Bf-committers] Carve vs. Bmesh booleans

Dear Blender devs, After the removal of Carve for booleans, which is an important part of the Fracture Modifier, I did some tests with Bmesh booleans to find out the differences and what we need to change in order to make FM work with that system. I'd like to share some of my observations and

Hi Mikhail, I wonder what makes you so certain that the Bmesh way is the way how a boolean tool is supposed to work? > Incorrect input should result in incorrect output. Sure, you can declare everything being incorrect input that your tool can't handle properly. Or you just can make it w

Thanks Kai. I am actively working on trying to improve the Bmesh booelans. This is useful input. - Howard Trickey On Wed, Apr 18, 2018 at 12:38 PM Kai Kostack wrote: > Dear Blender devs, > > After the removal of Carve for booleans, which is an important part of the > Fracture Modifier, I did so

Hi Kai and Howard, >> 1. Bmesh is leaving free edges in non-manifold results (well visible in orange in the lower right), those should be removed after operation. It is out of scope of a boolean tool, it should not try to fix geometry, it's just should perform a boolean operation. Incorrect input

Kai, > I actually don't think that we want nor need two different boolean tools in Blender if one can do it both. I was thinking towards Bisect tool with additional features: working with mesh planes, curves, GP and settings like "split distance". But this is also the add-ons territory, and they
