PRIMARY + SECONDARY · STEEL-BELT CVT UNIT

1 · Drive the unit

• Pick a gear — click any P / R / N / D / S pill at the top, or use the DRIVER INPUT panel (bottom-left).
• Throttle & brake — drag the sliders and watch a full physics model spin the pulleys, move the belt, and shift the ratio in real time.
• Try a fault — the fault selector injects a documented CVT fault so you can see how it presents (symptom + DTC pulse on the affected part).

2 · Read the data

• Left column — live telemetry (vehicle speed, engine RPM, line pressure, temperatures, solenoid currents) computed every frame.
• Signal-quality dot: ● measured · ● derived · ● estimated. Hover any chip for its confidence + source.
• Right column — DTC fault panel, spec sheet, and solenoid current detail.

3 · Inspect the 3D model

• Drag to orbit the camera · Scroll to zoom · Right-click drag to pan.
• EXPLODE — separates all components along the axis for a teardown view.
• SECTION — cuts the model with a clipping plane.
• WIREFRAME — X-ray view showing only the cyan edge overlay.
• AUTO ORBIT — camera spins continuously around the assembly.
• PRESENT — hides UI chrome for a clean visualisation on a TV.

4 · ✋ Hand control (camera + webcam)

• Click ✋ HAND CONTROL (or press G) and allow the camera. A live webcam HUD appears bottom-left with the detected gesture and an EXPANSION % meter.
• ✊ Make a fist to LOCK — freezes the unit at its current angle. Open your hand again to carry on. Use it to hold a view steady.
• 🖐 Open palm facing the camera = ROTATE — push physics: the surface follows your hand, so move right and it turns right, push up and it rolls up and over (a full 180°, top to bottom), with momentum — a firm flick keeps coasting after your hand stops.
• 🤚 Turn the BACK of your hand to the camera = EXPAND — the compartments separate; spread your fingers to open further, curl them to close. Flip your palm back to the camera and it holds where you left it while you rotate.
• Roll it further than your reach: flick to give it spin (it coasts on its own), then move your hand back slowly to reposition and flick again — like spinning a real globe.
• 🤏 Pinch (thumb + index, palm up) — move your hand up / down to zoom in and out.
• If your hand leaves the camera frame, the unit keeps its momentum and holds position + explode — just bring your hand back to carry on. Brief tracking dropouts are smoothed over.
• Click the button again (or RESET) to release hand control back to the mouse. Needs a webcam + internet (vision model loads from CDN). Nothing is recorded — all processing is in your browser.
