I think calcPathPoints can be made more efficient by calculating the slerp only once (for t = 1/segments), and then maintaining stepQuat like: // before the loop let stepQuat = new THREE.Quaternion(); // at end of loop body stepQuat.multiply(slerp); Sorry if this was discussed in the article already.
