Easing function for whole animation

[Kuangzheng_Xia]

I have a bezierTorus animation with three keyframes. After I set the easing function, it goes straight with speed up and slow, and then goes straight with speed up and slow. Is it possible for the whole animation, speed up and then slow?

    keysBezierTorus.push({ frame: 0, value: bezierTorus.position });
    keysBezierTorus.push({ frame: 120, value: bezierTorus.position.add(new BABYLON.Vector3(-40, 0, 0)) });
    keysBezierTorus.push({ frame: 240, value: bezierTorus.position.add(new BABYLON.Vector3(-80, 0, 0)) });

Hey you can actually use the Animation Curve Editor for that:
