What is the way to deal with 3D scanned model

Questions
1

I am using a scene scanned from an iPhone. In a scene scanned by iPhone, it looks like I can’t treat objects in the scene as 3D objects and the position of that object as a reference for another thing like creating the physics body of cannon-es.js

I am following this as a resource:

https://sbcode.net/threejs/physics-cannonDebugrenderer/

So I thought that I can add a physics body in the position where raycast intersect the 3d object in the scene and put 3d physics body in that place.

When it is placed in the scene, I want to be able to move it, scale it and select it so that I can manually make it’s size because it is not possible to find bounding geometry size in scanned model’s child objects.

I double clicked on chairs and i am able to place sphere in that position

but now i want to select them.

These physics body are visible by the

CannonDebugRenderer maintained and shared by @seanwasere .

This is my code to create a spahere:

function createPhysicsBody(e: MouseEvent) {
    event?.preventDefault()
    let mouse_position = new THREE.Vector2()
    mouse_position.x = (e.clientX / renderer.domElement.clientWidth) * 2 - 1
    mouse_position.y = -(e.clientY / renderer.domElement.clientHeight) * 2 + 1
    raycaster.setFromCamera(pointer, camera)
    const intersections = raycaster.intersectObjects(sceneObjects, true)
    let intersection = intersections.length > 0 ? intersections[0] : null
    if (intersection !== null) {
        let point = intersection.point
        let itemsBody = new CANNON.Body({
            mass: 0,
            shape: new CANNON.Sphere(5),
        })
        let itemsBodycopy = Object.assign(itemsBody, { name: 'chair' })
        console.log(itemsBodycopy)
        itemsBodycopy.position.copy(new CANNON.Vec3(point.x, point.y, point.z))
        world.addBody(itemsBodycopy)
    }
}

which is triggered by this:

renderer.domElement.addEventListener('dblclick', createPhysicsBody)

i added name element in the body with a hope that i will get this name in the CannonDebugRenderer

const cannonDebugRenderer = new CannonDebugRenderer(scene, world)

which i call

cannonDebugRenderer.update()

in animate function

i consoled in canonDebugRender, i found a mesh but could not find that name or anything !!

Is there anyway i can select this physics body so that i can do some work on the selected physics body.

Thank you
