Arc

Module Geometry.Arcs

In ixfx, a circle is simply an object with radius, or if it’s positioned it also has coordinates:

type Arc = {
  counterClockwise?: boolean;
  endRadian: number;
  radius: number;
  startRadian: number;
}
type ArcPositioned = Point & Arc;

Once you have that there are a bunch of functions to help you work with arcs.

  • bbox - compute bounding box
  • distanceCenter - compute distance of centers of two arcs
  • fromDegrees - Make an arc using degree angles
  • interpolate - compute relative position along circumference
  • length - compute length of arc
  • point - calculate a coordinate of arc based on angle
  • toLine - returns a Line connecting start and end points of arc
