pub struct Orbit {
    pub azimuth: f32,
    pub elevation: f32,
    pub zoom: f32,
}

Fields

pub azimuth: f32

Degrees around the target (positive = to the right).

pub elevation: f32

Degrees above the starting angle.

pub zoom: f32

Distance multiplier (< 1 is closer).

pub fn drag(&mut self, dx: f32, dy: f32)

Apply a pointer drag of (dx, dy) CSS pixels.

pub fn wheel(&mut self, delta: f32)

Apply a wheel delta (positive zooms out).

pub fn key(&mut self, key: &str) -> bool

Arrow keys rotate, +/- zoom; returns whether the key was used.
