hitTest

fun hitTest(session: Session, ray: Ray): List<HitResult>

Performs a hit-test using the given ray.

A hit-test is a method of calculating the intersection of a ray with objects tracked by the session. Conducting a hit-test results in a list of hit objects, in other words, a hit-test does not stop at the first object hit.

Returns
List<HitResult>

A list of HitResult objects, sorted by distance from the origin of the ray. The nearest hit is at the beginning of the list.
