interpolate-angle v1.0.2

interpolate-angle

Linear interpolation between two angles along the shorter arc

Usage

interpolateAngle(from, to, t)

Parameters:
from - angle in radians 0..2PI
to - angle in radians 0..2PI
t - interpolation ratio 0..1

var interpolateAngle = require('interpolate-angle');

interpolateAngle(0, 2 * Math.PI, 0.5) //-> PI
interpolateAngle(-Math.PI/6, Math.PI/6, 0.5) //-> 0
interpolateAngle(Math.PI*5/3, Math.PI/3, 0.25) //-> -1/6 PI
