Points

[
    {
        id: 0,
        position: { x: 1, y: 1, z: 1 },
        rotation: { x: 0, y: 0, z: 0 },
        // payload can be anything (e.g. target camera position)
        payload: {
            x: -0.9,
            y: 0.5,
            z: -1.1
        }
    },
    {
        id: 1,
        position: { x: 2, y: 4, z: -1 },
        rotation: { x: 1, y: 2, z: 0 },
        // payload can be anything
        payload: {
            x: -0.9,
            y: 0.5,
            z: -1.1
        }
    }
]

v-model

Animate positoin with e.g. Greensock:

<gltf-viewer url="path/to/model.gltf" 
             v-model="position" />

data() {
    return {
        position: {}
    }
},
methods: {
    tweenPosition() {
        let formPos = { ...this.position }
        let targetPos = { x: 1, y: 2, z: 3 }
        TweenLite.to(fromPos, 0.6, {
            ...targetPos,
            onUpdate: () => {
                this.position = fromPos
            }
        })
    }
}

Note that you cannot change the camera position via v-model if autoRotate is true!
