@3dlyra/curve3 v1.0.0

Curve3

This library is a curves part of the 3DLyra's math library.

Installation

npm i @3dlyra/curve3

Example

import * as Curve3 from "@3dlyra/curve3"
import * as Vector3 from "@3dlyra/vector3"

// Control points
const a = Vector3.create( - 5, 0, 0 )
const b = Vector3.create( 0, 5, 0 )
const c = Vector3.create( 5, 0, 0 )

// Divisions
const div = 4 // or a higher number for better smoothness

const vertices = Curve3.quadratic( a, b, c, div )

console.log( vertices )
/*

  -5,   0,      0,
  -2.5, 1.875,  0,
  0,    2.5,    0,
