squad
fun squad(q0: Quaternion, q1: Quaternion, s0: Quaternion, s1: Quaternion, t: Double, result: Quaternion): Quaternion(source)
Computes the spherical quadrangle interpolation between quaternions.
// 1. compute the squad interpolation between two quaternions on a curve
const s0 = Quaternion.computeInnerQuadrangle(quaternions[i - 1], quaternions[i], quaternions[i + 1], new Quaternion());
const s1 = Quaternion.computeInnerQuadrangle(quaternions[i], quaternions[i + 1], quaternions[i + 2], new Quaternion());
const q = Quaternion.squad(quaternions[i], quaternions[i + 1], s0, s1, t, new Quaternion());
// 2. compute the squad interpolation as above but where the first quaternion is a end point.
const s1 = Quaternion.computeInnerQuadrangle(quaternions[0], quaternions[1], quaternions[2], new Quaternion());
const q = Quaternion.squad(quaternions[0], quaternions[1], quaternions[0], s1, t, new Quaternion());Content copied to clipboard
