Clipper2 is a polygon clipping, offsetting, and triangulation library available in C++, C#, and Delphi. It performs boolean operations (intersection, union, difference, XOR) on simple and complex polygons, plus polygon offsetting and Constrained Delaunay Triangulation.

Use cases

• compute intersection or union of polygons
• perform boolean difference and XOR on complex polygons
• offset or inflate polygon outlines
• triangulate polygons with constrained Delaunay triangulation
• clip polygons in a graphics or CAD application
• use polygon clipping from C#, C++, or Delphi

When to choose

• you need robust polygon boolean operations or offsetting in C++, C#, or Delphi
• you want a well-documented, actively maintained computational geometry library
• you need cross-language access via a compiled DLL

When to avoid

• you need reliable polygon triangulation right now - the triangulation code is acknowledged as buggy
• you need 3D geometry operations
• you need a language other than C++, C#, or Delphi without going through a DLL
