Methods

AddCameraPoseKey(Single, MixedRealityPose, Single, Single)

Add a keyframe for the camera transform.

Declaration

public void AddCameraPoseKey(float time, MixedRealityPose cameraPose, float positionThreshold, float rotationThreshold)

Parameters

Type	Name	Description
Single	time
MixedRealityPose	cameraPose
Single	positionThreshold
Single	rotationThreshold

AddHandJointKey(Single, Handedness, TrackedHandJoint, MixedRealityPose, Single, Single)

Add a keyframe for one hand joint.

Declaration

public void AddHandJointKey(float time, Handedness handedness, TrackedHandJoint joint, MixedRealityPose jointPose, float positionThreshold, float rotationThreshold)

Parameters

Type	Name	Description
Single	time
Handedness	handedness
TrackedHandJoint	joint
MixedRealityPose	jointPose
Single	positionThreshold
Single	rotationThreshold

AddHandStateKey(Single, Handedness, Boolean, Boolean)

Add a keyframe for the tracking state of a hand.

Declaration

public void AddHandStateKey(float time, Handedness handedness, bool isTracked, bool isPinching)

Parameters

Type	Name	Description
Single	time
Handedness	handedness
Boolean	isTracked
Boolean	isPinching

AddMarker(InputAnimationMarker)

Add a user-defined marker.

Declaration

public void AddMarker(InputAnimationMarker marker)

Parameters

Type	Name	Description
InputAnimationMarker	marker

Clear()

Remove all keyframes from all animation curves.

Declaration

public void Clear()

CreateHandJointCurves(Handedness, TrackedHandJoint)

Make sure the pose animation curves for the given hand joint exist.

Declaration

public InputAnimation.PoseCurves CreateHandJointCurves(Handedness handedness, TrackedHandJoint joint)

Parameters

Type	Name	Description
Handedness	handedness
TrackedHandJoint	joint

Returns

Type	Description
InputAnimation.PoseCurves

CutoffBeforeTime(Single)

Remove all keyframes from all animation curves with time values before the given cutoff time.

Declaration

public void CutoffBeforeTime(float time)

Parameters

Type	Name	Description
Single	time

Remarks

If keyframes exists before the cutoff time then one preceding keyframe will be retained, so that interpolation at the cutoff time yields the same result.

EvaluateCameraPose(Single)

Evaluate the camera transform at the given time.

Declaration

public MixedRealityPose EvaluateCameraPose(float time)

Parameters

Type	Name	Description
Single	time

Returns

Type	Description
MixedRealityPose

EvaluateHandJoint(Single, Handedness, TrackedHandJoint)

Evaluate joint pose at the given time.

Declaration

public MixedRealityPose EvaluateHandJoint(float time, Handedness handedness, TrackedHandJoint joint)

Parameters

Type	Name	Description
Single	time
Handedness	handedness
TrackedHandJoint	joint

Returns

Type	Description
MixedRealityPose

EvaluateHandState(Single, Handedness, out Boolean, out Boolean)

Evaluate hand tracking state at the given time.

Declaration

public void EvaluateHandState(float time, Handedness handedness, out bool isTracked, out bool isPinching)

Parameters

Type	Name	Description
Single	time
Handedness	handedness
Boolean	isTracked
Boolean	isPinching

FindMarkerInterval(Single)

Find an index i in the sorted events list, such that events[i].time <= time < events[i+1].time.

Declaration

public int FindMarkerInterval(float time)

Parameters

Type	Name	Description
Single	time

Returns

Type	Description
Int32	0 <= i < eventCount if a full interval could be found. -1 if time is less than the first event time. eventCount-1 if time is greater than the last event time.

Remarks

Uses binary search.
