How it works

Real VR controllers don't report a throw velocity directly — headset SDKs estimate it from a short history of tracked poses using finite differences:

v = (p[n] - p[n-1]) / Δt

Raw single-sample velocity is noisy: a small jitter right at release can spike the estimate and send the throw wildly off target. Production SDKs (Quest, Vive, PSVR2) instead average velocity over the last few tracked samples before release — trading a little responsiveness for consistency. This sim's Velocity filter toggle switches between the two so you can feel the difference directly.

Once released, the ball is a free projectile under constant gravity g — no drag modeled, matching how most VR arcade throwing games simplify physics for readable, catchable trajectories:

x(t) = x0 + vx·t
y(t) = y0 + vy·t − ½·g·t²
z(t) = z0 + vz·t

A hit is scored when the ball's trajectory crosses the target's distance plane while still inside the ring radius. Moving the target farther out, or raising gravity, shrinks the launch-angle window that lands inside the ring — exactly the difficulty tuning real VR arcade titles use.
