Based on the book http://www.jeffreythompson.org/collision-detection/table_of_contents.php

Mostly used for vector 2d intersections checking for Pixie: https://github.com/treeform/pixie

Supported intersections:

Shape	Point	Circle	Rectangle	Segment	Polygon	Line	Wedge
Point	✅	✅	✅	✅	✅	✅	✅
Circle	✅	✅	✅	✅	✅	✅	✅
Rectangle	✅	✅	✅	✅	✅	✅	✅
Segment	✅	✅	✅	✅	✅	✅	✅
Polygon	✅	✅	✅	✅	✅	✅	✅
Line	✅	✅	✅	✅	✅	✅	✅
Wedge	✅	✅	✅	✅	✅	✅	✅

All shapes support overlaps.

if overlaps(circle, point):
  echo "Circle and point overlap"

if contains(circle, point):
  echo "Circle contains point"

And some shapes support intersects functions.

var at: Vec2
if intersects(circle, segment, at):
  echo "Circle and segment intersect at ", at

var at: Vec2
if intersects(circle, polygon, at):
  echo "Circle and polygon intersect at ", at
