quat-slerp

Standalone spherical interpolation for quaternions, from gl-matrix.

var slerp = require('quat-slerp')

var out = []
slerp(out, [0, 0, 0, 1], [0, 1, 0, 0], 0.5)

// out is now [0, 0.707106, 0, 0.707106]

Usage

slerp(out, a, b, t)

Interpolates from quaternion a to b with the given t alpha, storing the result in out. Returns the out quaternion.

out, a and b are all 4-component arrays in the form [x, y, z, w].
