Tween camera position while rotation with slerp — THREE.js

Question

I want to tween camera position while rotation.

Here is my function:

function moveAndLookAt(camera, d         


        

Answer 1

In your code

// rotation (using slerp)
(function () {
var qa = camera.quaternion; // src quaternion

Change it to

qa = new THREE.Quaternion().copy(camera.quaternion); // src quaternion

The way you do it, qa is the same as the camera quaternion, and it feeds back in the slerp calculus. It must be a constant variable.
