Navigating in 3D

The 3D view has four camera modes. Switch with the keys below or from Tools. Esc returns to Orbit.

Orbit (default)

Input	Action
Left-drag	Rotate around the target
Right-drag	Pan
Wheel	Zoom towards the cursor
Arrow keys (canvas focused)	Orbit
+ / −	Zoom in / out
R	Reset camera
N	Face north
One finger / pinch / two fingers	Rotate / zoom / pan on touch screens

Walk (F)

First-person on the terrain surface, with pointer lock.

Input	Action
Mouse	Look around
W A S D	Move
Shift	Run
Space / C	Up / down
Esc	Release the pointer, then leave walk mode

Flight (G)

A simple flight model over the scene. Gamepads are supported.

Input	Action
W / S	Throttle up / down
Arrow keys	Pitch and roll
Q / E	Yaw
Shift	Boost
R	Level out

Drone tour (T)

An automatic flight path around the scene, with play / pause and a speed slider (0.2–4×). Useful for demos and screen recordings.

HUD and mini-map

In Walk and Flight modes, a heads-up display shows a heading tape and read-outs: AGL (height above ground), ALT (altitude), HDG (heading), plus SPD, PIT and ROL in flight. A mini-map shows your position over the height map.

Performance

• Choose Mesh detail (Fast / Balanced / Full) in Inspector → Layers. Fast keeps navigation smooth on laptops.
• Ambient occlusion and anti-aliasing switch off automatically when the frame rate drops. The fps read-out in the status bar turns orange below 30.
• If WebGL is unavailable, a fallback screen explains why. All three views share the same WebGL canvas.

Tip

Vertical exaggeration (Inspector → Layers, 0.2–8×) makes low relief visible, but reset it to 1× before taking screenshots that others will read as true scale.
