2D Geometry Clipping

[LuizZak]

A tentative implementation of boolean operations on 2-dimensional non-intersecting shapes made up of lines and arcs, the result of which is not a raster output but instead other lines and arcs.

Sample of a union between a circle and a hexagon:

A small interactive sample of the generated clipped geometry along with how the periods map to a scalar value is available on p5js:

Checklist

• Define final clipping geometry type API
• Implement tolerance in new unit test APIs and new unit tests
• Implement Union boolean operation
• Implement Intersection boolean operation
• Implement Subtraction boolean operation
• Derive a better name, as 'periodic geometry' relates to crystal and prism-like geometric grids that repeat periodically
  • Renamed to GeometriaClipping
• Support holes as extra contours within a geometry
• Apply optimizations and inlinable attributes
  • Optimize compound geometry inversion
• Handle interference of vertices/edges
