Finds the closest hit when traversing the tile hierarchy

This function performs hierarchical raycasting against the tile hierarchy, finding the closest intersection by traversing bounding volumes and testing actual scene content only when necessary.

Signature:

export declare function raycastTraverseFirstHit(renderer: TilesRenderer, tile: ITile, raycaster: Raycaster, localRay?: Ray | null): TileIntersection | null;

Parameters

Parameter	Type	Description
renderer	TilesRenderer	The tiles renderer instance
tile	ITile	The root tile to start traversal from
raycaster	Raycaster	The raycaster to use
localRay	Ray | null	(Optional) Pre-calculated local ray (optional)

Returns:

[TileIntersection](./flywave-3dtile-datasource.tileintersection.md) \| null

The closest intersection or null if none found
