Overview

Package path simplifies paths of 2-dimensional points.

Index

• func OfFloatPoints(pt func(i int) (x, y float64), len int) path

Functions

func OfFloatPoints

func OfFloatPoints(pt func(i int) (x, y float64), len int) path

OfFloatPoints creates an abstract path of float64 2d points.

The path has a length len and float64 2d coordinates for each point at index i with 0 <= i < len.

func OfIntPoints

func OfIntPoints(pt func(i int) (x, y int), len int) path

OfIntPoints creates an abstract path of integer 2d points.

The path has a length len and integer 2d coordinates for each point at index i with 0 <= i < len.

func Simplify

func Simplify(path path, epsilon float64) []int

Simplify finds representative points in the given path and returns their indices. The path is given through the abstract path interface, which is constructed with one of the helpers in the same package.
