Function getLaneWorldPoint

getLaneWorldPoint(
    group: Group,
    exitIndex: number,
    laneIndex: number,
    which: "end" | "start",
    dir: "in" | "out",
): any
Returns the world-space midpoint of a specific lane strip at a junction exit.

Lane lines are boundary lines, so N lanes = N + 1 boundary lines, meaning strip laneIndex sits between boundary lines laneIndex and laneIndex + 1. Inbound lanes are indexed in reverse order relative to outbound lanes since they occupy the opposite side of the exit road.
Parameters
- group: Group
  The Three.js group of the junction object.
- exitIndex: number
  Which exit arm on the junction.
- laneIndex: number
  Which lane strip within that exit (0 = leftmost/nearside).
- which: "end" | "start"
  "start" (junction-side) or "end" (road-side) of the lane.
- dir: "in" | "out"
  "in" for inbound lanes, "out" for outbound.
Returns any
The world-space midpoint of the requested lane strip endpoint.
