Show wireframe on actual physics impostor?

Questions
1

I see there used to be a PhysicsImpostorHelper however it seems to be no longer working.

I know there is mesh.showBoundingBox but the bounding box of the mesh is not an accurate representation of the physicsImpostor applied to it.

Is there anything like mesh.physicsImpostor.showBoundingBox?

We still have the helper:

Its name is BABYLON.PhysicsViewer

Thank you!

I want to know what is showBoundingBox?Does the model itself have a bounding box? So if the model itself has a bounding box, why create a bounding box? If not, what does it do

Every mesh has a bounding box (call `mesh.getBoundingInfo().boundingBox)

It is used to do the frustum culling
