説明

Casts a ray from a screen point against selected trackables (e.g., planes and feature points).

Casts a ray from a screen position against selected trackables in the Scene. trackableTypeMask defaults to TrackableType.All.

説明

Casts a ray using ray against selected trackables (e.g., planes and feature points).

Use this method to raycast against selected trackables in the Scene. trackableTypeMask defaults to TrackableType.All.

When raycasting against TrackableType.FeaturePoint, Unity uses a cone defined by pointCloudRaycastAngleInDegrees. It defaults to 5 degrees.
