3D Track Replay

WebGL 3D track reconstruction with ghost cars, free camera, and live telemetry overlay.

Last updated July 14, 2026

Summarize this page with AI

The 3D Replay view renders a WebGL track model with your car and ghost vehicles synchronized to replay time. Use it when you want to see the car on track, orbit corners, or capture clean screenshots.

3D track replay — WebGL track with ghost car
3D track replay — WebGL track with ghost car

Enable 3D

Press M or click the 2D/3D toggle in the top-left toolbar.

What you see

ElementWhat it does
3D track surfaceCircuit mesh aligned to your telemetry
Your carLive position during replay
Ghost car(s)Up to two reference cars in Custom ghost mode
Racing linesOptional paths on the track — toggle in display preferences
Sector labelsS1/S2/S3 on the track surface during replay
Data HUD cardsLive inputs above cars when Data overlay is on
Segment mini mapTop-right when traces are closed; compact strip beside traces when open — see Segment mini map

Follow car camera

Turn Follow car on in the toolbar for a chase-style camera. On desktop, a panel appears beside the toolbar:

ControlEffect
DistanceHow far the camera sits from the car
ChaseOrbit around the car (default)
FrontHood / forward camera
BackRear camera looking behind

Use Reset View to return to the default chase camera and clear any corner preset.

Turn Follow car off for free camera movement. Preset corner cameras from Overlays → Corners override follow until you pick Clear preset.

Follow-car state carries over when you switch 2D ↔ 3D.

Ghost cars in 3D

Reference modeGhost cars on track
Best lapOne ghost car
Custom (picked lap)One ghost via Laps overlay 1 slot; second via 2 slot
External / CommunityOne ghost car

Toggle ghost car visibility with the car icon in the driver strip or traces toolbar. The dashed Ghost lap line on the track is separate — toggle it in display preferences.

Overlays for 3D

These launch from the Overlays tab — see Overlays and modals:

ButtonWhat it does
DataFloating HUD above your car and each ghost — gear, throttle, brake, steering
CornersTurn list (T1, T2, …) with preset orbit cameras per apex
Tyres, Brakes, etc.Same draggable popups as 2D

Data and Corners only appear in 3D. In cinema mode, HUD cards hide with the rest of the chrome.

Free camera controls

When Follow car is off:

ActionControl
Fly forward / backW / S
Strafe left / rightA / D
Move up / downE / Q
Orbit / rotateLeft-click + drag
PanRight-click + drag
ZoomScroll wheel

Cinema mode

Cinema mode is 3D only. Press ⌘ + ⇧ + U (Mac) or Ctrl + Shift + U (Windows/Linux) to hide all map chrome — toolbar, driver strip, replay bar, traces, mini map, and overlays.

What remains:

  • The 3D scene and ghost cars (if visible)
  • Save 3D screenshot button (top-right) — exports a PNG

Press Esc to exit cinema mode. See Fullscreen and cinema mode.

Performance

3D is graphically intensive. Files over 50 MB may stutter. Switch to 2D map if lag occurs. Close unused overlay popups on large files.

Suggested workflow

  1. Load a reference ghost from the driver strip
  2. Turn Follow car on with Chase camera for a driving replay
  3. Open Data overlay to see live inputs on the cars
  4. For a specific corner, open Corners and pick a turn — or switch to 2D for comparison markers
