Orbit and fly

The page decides which modes exist. modes: ['orbit', 'fly'] (the default) offers both: F or the pad’s Y button switches, Esc leaves fly mode, and leaving puts the orbit point straight ahead at the same distance, so the view does not jump. modes: ['fly'] gives a fly-only viewer and modes: ['orbit'] an orbit-only one; with one mode the switch does nothing and is left out of bindings. setMode('fly') switches in code.

	Orbit	Fly
Mouse	drag to rotate and pan; the wheel zooms toward the cursor	look around (pointer lock after a click, or drag); the wheel sets the speed
WASD, arrows	move the orbit point along the ground	move where you look, pitch included
Q/E, C/Space	down and up	down and up
Shift, Ctrl	x4, x0.25	x4, x0.25
Left stick	move	move, with a response curve
Right stick	rotate around the orbit point	look from where you are
Triggers, LB/RB, stick click, A	down and up, speed steps, x4, home	the same
One finger	rotate (rotate-left) or pan (pan-left)	look around
Two fingers	pinch zooms by the finger ratio; dragging pans (rotate-left) or rotates and tilts (pan-left)	drag moves like a stick held away from where it began; pinch sets the speed
On-screen joystick (optional)		moves, like WASD; any other touch looks

Fly speed per second is a fraction (speed.rangeFactor, 0.5) of your height above the surface when the page supplies surfaceAt(x, z) (scene units in and out), so low passes are slow and high ones fast; without it, of the distance to the orbit point when fly mode began. Movement eases in and out over about 0.15 s. The fly settings sensitivity (degrees per pixel), invertY and curve can be changed with setFlySettings() and remembered per browser with settingsKey. Flying through terrain is allowed.
