"WebRaycasting. At its most basic level, raycasting is the act of sending out an invisible ray from a Vector3 point in a specific direction with a defined length. Once cast, you can detect if the ray hits a BasePart or Terrain cell. Lasers are fired by floating orbs, and raycasting determines whether a laser hits a platform. " - Ray cast implicit surface
