How to save the exact position of camera?

Hi,

I recently needed to implement this so I thought I’d add to the discussion. To save the camera’s position, zoom, and rotation and the controls target I did the following inside my animation frame:

onTick () {
   
localStorage.setItem("camera.position.x", camera.position.x.toString())
localStorage.setItem("camera.position.y", camera.position.y.toString())
localStorage.setItem("camera.position.z", camera.position.z.toString())
localStorage.setItem("camera.rotation.x", camera.rotation.x.toString())
localStorage.setItem("camera.rotation.y", camera.rotation.y.toString())
localStorage.setItem("camera.rotation.z", camera.rotation.z.toString())
localStorage.setItem("camera.zoom", camera.zoom.toString())

localStorage.setItem("controls.target.x", controls.target.x.toString())
localStorage.setItem("controls.target.y", controls.target.y.toString())
localStorage.setItem("controls.target.z", controls.target.z.toString())
  }

I then retrieved this information in my init function:

camera.position.x = parseFloat(localStorage.getItem("camera.position.x"))
camera.position.y = parseFloat(localStorage.getItem("camera.position.y"))
camera.position.z = parseFloat(localStorage.getItem("camera.position.z"))

camera.rotation.x = parseFloat(localStorage.getItem("camera.rotation.x"))
camera.rotation.y = parseFloat(localStorage.getItem("camera.rotation.y"))
camera.rotation.z = parseFloat(localStorage.getItem("camera.rotation.z"))

camera.zoom = parseFloat(localStorage.getItem("camera.zoom"))

//camera.updateProjectionMatrix()

controls.target.x = parseFloat(localStorage.getItem("controls.target.x"))
controls.target.y = parseFloat(localStorage.getItem("controls.target.y"))
controls.target.z = parseFloat(localStorage.getItem("controls.target.z"))

As @Mugen87 mentioned, it seems that everything works fine without the camera.updateProjectionMatrix() part so I commented it out. Btw, localStorage is a JavaScript function. Hope this is useful to someone. The localStorage.setItem("camera.zoom", camera.zoom.toString()) is needed because otherwise the zoom is not saved
