@relu-interactives/spatial-ecs / index / ThrowVelocityTracker

Class: ThrowVelocityTracker

Defined in: xr/throwVelocity.ts:52

Rolling buffer of hand positions used to recover throw velocity.

One per active grab; cleared on release.

Constructors

Constructor

new ThrowVelocityTracker(): ThrowVelocityTracker;

Returns

ThrowVelocityTracker

Methods

record()

record(position, time): void;

Defined in: xr/throwVelocity.ts:56

Record where the hand is now. Call once per frame while held.

Parameters

Parameter	Type
position	Vector3
time	number

Returns

void

---

computeVelocity()

computeVelocity(now): Vector3;

Defined in: xr/throwVelocity.ts:71

Velocity to release with, in metres/second.

Uses the FASTEST segment inside the window rather than the most recent or the window average. Users decelerate as they open their hand, so the last segment understates the throw and the average washes it out; peak speed is what matches the motion the user actually felt they made.

Parameters

Parameter	Type
now	number

Returns

Vector3

clear()

clear(): void;

Defined in: xr/throwVelocity.ts:105

Returns

void
