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].
