lerp the Camera LookAt

[carmandale]

I am using this...

useFrame((state, delta) => { const step = 0.1 state.camera.fov = THREE.MathUtils.lerp(state.camera.fov, zoom ? 10 : 42, step) state.camera.position.lerp(dummy.set(zoom ? 25 : 10, zoom ? 1 : 5, zoom ? 0 : 10), step) state.camera.lookAt(0, 0, 0) state.camera.updateProjectionMatrix() light.current.position.lerp(dummy.set(zoom ? 4 : 0, zoom ? 3 : 8, zoom ? 3 : 5), step) })

from this:
https://codesandbox.io/s/r3f-basic-demo-nsb7f?file=/src/App.js:597-994

and I want to also lerp the lookAt. I can't seem to figure out how to make that work. I thought it would be like the camera.position since that is also a vector3.

can anyone help?

thanks,
Dale
