Boolean operations API about bezierjs HOT 7 CLOSED

agreed, making as enhancement, although I've been unhappy with the code that's been in place on bezierinfo for quite a while now. I need to find some time to actually write a better implementation, but that time's hard to come by.

@Pomax What is wrong with the existing implementation you have done in Processing? Does it fail with some edge cases?

from bezierjs.

yeah, it doesn't deal with colinear overlap, or point incidence (e.g. two shapes overlapping on the same hull point). It forms ... rather weird things

from bezierjs.

What do you think about VectorBoolean library that is used by Sketch.app? The library was initially written in Objective-C, but there is a Swift port which should be rather easy to port to JavaScript.

I was also thinking about porting the new intersection graph from 2Geom. Both VectorBoolean and 2Geom implementations look solid, but I find the 2Geom C++ code much harder to understand.

honestly at this point I'm using paper.js for shape operations, as it has pretty well implemented boolean operation support. (see http://paperjs.org/reference/compoundpath/#unite-path etc).

Example of use in another project: https://github.com/Pomax/quick-glyph-maker/blob/gh-pages/utils.js#L29

@Pomax Thanks for hint, I wasn't aware of the recent improvements to Paper.js, it looks like it can handle almost all edge cases now.

closing as I'm using paper.js for this myself.
