Functions

worldBoundingSector

open override fun worldBoundingSector(globe: Globe, tileToWorld: Matrix4, result: Sector): Sector

Walk ±worldRadius along each ECEF axis from the world-space sphere center, project, union. Coarse but conservative — sufficient for fly-to framing.

worldBoundingSphere

open override fun worldBoundingSphere(globe: Globe, tileToWorld: Matrix4, result: BoundingSphere): BoundingSphere

Conservative world-space sphere used for frustum culling + nearest-point distance.
