New library : purescript-geometria (was purescript-geometry-plane)

purescript-geometria

A library to build geometric abstractions from

points, vectors, lines, half-lines, segments in any dimension
circles and ellipses in 2-dimension
using intersections to define new 2-dimension points .

No graphical backend is provided.

Example

Ebmtranceboy/purescript-geometria/blob/main/test/Test/Main.purs

module Test.Main where

import Prelude

import Data.Array (head, any)
import Data.Array (length) as Array
import Data.Geometria
  ( class Analytic
  , circle
  , dot
  , halfline
  , length
  , line
  , meets
  , middle
  , normalTo
  , point
  , quadratic
  , segment
  , toCoordinates

Edit 18AUG2019: version 2.0.0 refactoring breaks compatibility. Effect is no more, the lib is entirely pure (see README).
Edit 11SEP2020: geometry-plane version 1.0.1 : Since there is no rendering instructions anymore, choice is yours to use it with canvas, SVG, …
Edit 28JUL2024: geometria version 2.1.0 : The implementation of the ellipses’ intersections algorithm (via 3D-projection) was the occasion to remove the planar constraints for the basic types (Point, Vector…) that are polymorphic from now on. point zero :: Point 2 is the planar origin, point zero :: Point 3 is the spatial origin, and so on. I want to thank the PureScript community to make it possible to create such precise, concise and elegant definitions !
