Circle2d

Circle2d

A Circle2d is defined by its center point and radius. This module includes functionality for

  • Constructing circles through points or with a given center/radius
  • Scaling, rotating and translating circles
  • Extracting properties of circles like area, center point and radius
type alias Circle2d =
Circle2d
