Set the camera's near/far planes from its altitude every frame.
Keep the camera at least this far above the ground, metres (scaled down near minDistance).
Smoothing of motion (0 = none, 0.9 = very smooth).
Farthest, metres. 0 = automatic (6 planet radii, or 80 km on flat worlds).
Highest view angle (straight down = π/2), radians.
Closest the camera gets to the focus point, metres (0.01 ≈ an ant's eye).
Lowest view angle above the horizon, radians.
Pan / WASD speed as a fraction of the camera distance per second.
Drag rotation speed.
Wheel zoom speed (exponential, so it feels the same at every scale).
