Class: BabylonHitTester

Defined in: babylon-interactions/src/hit-tester.ts:56

Resolves which interactable a ray or a proximity probe touches. Implemented by the adapter (three.js Raycaster, engine BVH, …). A provider that pre-resolves targeting (IWSDK) may make this redundant - provider hints always take precedence over hit-tester results.
