Unity3D: A set of helper classes for 2D geometric calculations.

Geometry2D

A set of 2D Geometric helper components and structs for Unity3D. All structs are immutable. Useful for many things including calculating intersections, projections, distances and lerping.

Structs

• Line2D - A line between point a and point b.
• Triangle2D - A 3-gon defined by point a, b and c. Can be converted into an array of Line2D.
• Polygon2D - An n-gon defined by an array of points. Can be converted into an array of Triangle2D or Line2D.
• Bounds2D - A simple axis-alligned bounding box for fast collision checks.

Components

• Area2D - Lets you assign and edit a polygon in 3D-space for various purposes.

Extensions

• Geometry2D - Contains extension methods for Vector2.
