static void Oculus.Interaction.HandGrab.HandGrabInteraction.CalculateBestGrab ( this IHandGrabInteractor handGrabInteractor, IHandGrabInteractable interactable, GrabTypeFlags grabFlags, out GrabTypeFlags activeGrabFlags, ref HandGrabResult result )
Calculates a new target. That is the point of the interactable at which the HandGrab will happen. Parameters handGrabInteractor The interactor grabbing interactable The interactable to be HandGrabbed grabFlags The supported GrabTypes activeGrabFlags The anchor to use for grabbing result The a variable to store the result

static IMovement Oculus.Interaction.HandGrab.HandGrabInteraction.GenerateMovement ( this IHandGrabInteractor handGrabInteractor, IHandGrabInteractable interactable )
Initiates the movement of the Interactable with the current HandGrabTarget. Parameters handGrabInteractor The interactor grabbing interactable The interactable to be HandGrabbed

static Pose Oculus.Interaction.HandGrab.HandGrabInteraction.GetHandGrabPose ( this IHandGrabInteractor handGrabInteractor )
Gets the current pose of the current grabbing point. Returns The pose in world coordinates

static GrabPoseScore Oculus.Interaction.HandGrab.HandGrabInteraction.GetPoseScore ( this IHandGrabInteractor handGrabInteractor, IHandGrabInteractable interactable, GrabTypeFlags grabTypes, ref HandGrabResult result )
Calculates the GrabPoseScore for an interactable with the given grab modes. Parameters handGrabInteractor The interactor grabbing interactable The interactable to measure to grabTypes The supported grab types for the grab result Calculating the score requires finding the best grab pose. It is stored here. Returns The best GrabPoseScore considering the grabtypes at the interactable

static GrabPoseScore Oculus.Interaction.HandGrab.HandGrabInteraction.GetPoseScore
( this IHandGrabInteractor handGrabInteractor,
IHandGrabInteractable interactable,
GrabTypeFlags grabTypes,
ref HandGrabResult result )

Calculates the GrabPoseScore for an interactable with the given grab modes.

Parameters

handGrabInteractor

The interactor grabbing

interactable

The interactable to measure to

grabTypes

The supported grab types for the grab

result

Calculating the score requires finding the best grab pose. It is stored here.

Returns

The best GrabPoseScore considering the grabtypes at the interactable

static bool Oculus.Interaction.HandGrab.HandGrabInteraction.CanInteractWith ( this IHandGrabInteractor handGrabInteractor, IHandGrabInteractable handGrabInteractable )
Indicates if an interactor can interact with (hover and select) and interactable. This depends on the handedness and the valid grab types of both elements Parameters handGrabInteractor The interactor grabbing handGrabInteractable The interactable to be grabbed Returns True if the interactor could grab the interactable

static Pose Oculus.Interaction.HandGrab.HandGrabInteraction.GetGrabOffset ( this IHandGrabInteractor handGrabInteractor )
Calculates the offset from the Wrist to the actual grabbing point defined by the current anchor in the interactor HandGrabTarget. Parameters handGrabInteractor The interactor whose HandGrabTarget to inspect Returns The local offset from the wrist to the grab point

static float Oculus.Interaction.HandGrab.HandGrabInteraction.ComputeHandGrabScore ( IHandGrabInteractor handGrabInteractor, IHandGrabInteractable handGrabInteractable, out GrabTypeFlags handGrabTypes, bool includeSelecting )
