init(origin:direction:allowing:alignment:)

Creates a new raycast query.

Declaration

init(origin: simd_float3, direction: simd_float3, allowing target: ARRaycastQuery.Target, alignment: ARRaycastQuery.TargetAlignment)

Parameters

  • origin:

    A 3D position that describes the raycast’s starting point.

  • direction:

    A 3D vector that describes the raycast’s direction.

  • target:

    The type of plane with which you allow the raycast to intersect.

  • alignment:

    The target’s alignment with respect to gravity with which you allow the raycast to intersect.

Discussion

This creates a query by supplying a 3D starting place and vector. To acquire a raycast query using a screen point and vector that points outward from the user, call raycastQuery(from:allowing:alignment:) on ARSCNView.
