15. Raycasting in BabylonJS

Raycasting is incredibly useful for detecting other objects using a "ray". These are commonly used for "hitscan" weapons in first-person shooters. Raycasting creates an invisible line within our scene that we can use to detect other meshes. We can then get specifics about what we hit to include the exact Vector3 position of the hit, what mesh we hit, or even just check for a generic hit.
