polygon

this is a polygon related library. with this you can generate ramdon polygon, point contain test, polygon clipping, get convex hull etc. cc0. just enjoy it!

polygon's Issues

License?

First of all, thanks for making this available on github.
What's the license on this code? I wanted to use this to help merge collision boxes in a love game

docs / sources

Hi,

I'm interested in the polybool algorithm. It would be nice if you could add som documentation of usage, limitations and links to sources of the algorithms you use.

Thanks!

trying to do certain things with this, certain overlaps result in strange shapes, hole punching i can't seem to manage

Hi

two squares:
p1{ 100, 100, 200, 100, 200, 200, 100, 200 }
p2{ 150, 100, 250, 100, 250, 200, 150, 200 }

"not" =>

p3{ { 150, 100, 150, 200, 150, 200, 100, 200, 100, 100 }, { 200, 100, 250, 100, 250, 200, 200, 200, 200, 100 } }

I was trying to figure out why this happens, i imagine what I'm doing is bad practise but I still liked to figure it out!

also the "donut", slicing a hole in the middle:

p1 { 100, 100, 200, 100, 200, 200, 100, 200 }
p2 { 120, 120, 180, 120, 180, 180, 120, 180 }
p3 { 100, 100, 200, 100, 200, 200, 100, 200, 120, 120, 180, 120, 180, 180, 120, 180 }

I appreciate for the donut, we perhaps just have to do some work here, it's not gonna be possible to return a triangulate

I was working on a framework and investigating the possibility of dynamic terrain destruction, I have already wrote some polygon reduction code

attached is a very simple testing demo for the latest love 2d version:
