RANSACVelocity Class

A helper class that uses an underlying RandomSampleConsensus<TModel> to select the best pair of linear and angular velocities from a buffer of recent timed poses.

RANSACVelocity allows for the stable estimation of velocity under noise-prone circumstances. This is particuarly important when throwing objects because of the unreliability of data around the moment of intended release: if the perceived moment of release is slightly too late, for example, the behavior of the throwing implement (hand, controller, etc.) should not impact the calculated velocity. RANSAC velocity estimation across several frames mitigates this problem.

Constructors

RANSACVelocity ( samplesCount , samplesDeadZone , minHighConfidenceSamples )	Signature Oculus.Interaction.Throw.RANSACVelocity.RANSACVelocity(int samplesCount=10, int samplesDeadZone=2, int minHighConfidenceSamples=2) Parameters `samplesCount: int` `samplesDeadZone: int` `minHighConfidenceSamples: int`
RANSACVelocity ( samplesCount , samplesDeadZone )	Creates a new RANSACVelocity for estimating velocity. Signature Oculus.Interaction.Throw.RANSACVelocity.RANSACVelocity(int samplesCount=10, int samplesDeadZone=2) Parameters `samplesCount: int` The size of the rolling sample buffer from which to seek consensus. `samplesDeadZone: int` The number of most recent samples to exclude from the consensus.

Properties

MaxSyntheticSpeed : float

[Get][Set]

Maximum speed (in m/s) allowed for synthetic poses.

This is used in internal calculations and should generally not need to be tuned.

Synthetic poses are generated and used by RANSACVelocity to fill tracking gaps (when Input.IHand.IsHighConfidence for a tracked hand is false, for example). Capping the allowed speed mitigates the risk of generating nonsensical synthetic poses.

GetSortedTimePoses ( idx1 , idx2 , older , younger )	Signature void Oculus.Interaction.Throw.RANSACVelocity.GetSortedTimePoses(int idx1, int idx2, out TimedPose older, out TimedPose younger) Parameters `idx1: int` `idx2: int` `older: out TimedPose` `younger: out TimedPose` Returns `void`
PositionOffset ( youngerPose , olderPose )	Signature virtual Vector3 Oculus.Interaction.Throw.RANSACVelocity.PositionOffset(Pose youngerPose, Pose olderPose) Parameters `youngerPose: Pose` `olderPose: Pose` Returns `Vector3`

GetVelocities ( velocity , torque )	Estimates the current translational and rotational velocities based on the available data. If there is insufficient data to produce an estimate, returns 0 trivial velocities. Signature void Oculus.Interaction.Throw.RANSACVelocity.GetVelocities(out Vector3 velocity, out Vector3 torque) Parameters `velocity: out Vector3` Output parameter for translational velocity. `torque: out Vector3` Output parameter for rotational velocity. Returns `void`
Initialize ()	Initializes a RANSACVelocity calculator, clearing its state and preparing it to receive new data. Can be called repeatedly to reset the state of an existing RANSACVelocity. Signature void Oculus.Interaction.Throw.RANSACVelocity.Initialize() Returns `void`
Process ( pose , time , isHighConfidence )	Consumes a new frame of Pose data for example, from the IGrabbable.Transform of a grabbed GrabInteractable. The RANSACVelocity instance must be regularly supplied with such data so that velocities can be estimated when needed. Signature void Oculus.Interaction.Throw.RANSACVelocity.Process(Pose pose, float time, bool isHighConfidence=true) Parameters `pose: Pose` The Pose observed. `time: float` The time at which pose was observed. `isHighConfidence: bool` Whether or not pose was observed with high confidence. For example, if pose is from an IGrabbable.Transform being held by an Input.IHand for which Input.IHand.IsHighConfidence is false, then pose might also be considered to be known with low confidence. Returns `void`
