Expand description

Parametric knobs for the rabbit silhouette. All in the normalised [-1, 1] design box (y up). Rabbit::default is the tuned mascot; tests and renderers should use it so the geometry is the same everywhere.

Fields§

§body_cy: f64

Body ellipse centre + radii (the sitting haunch).

§body_rx: f64§body_ry: f64§head_cx: f64

Head circle centre + radius (sits above/forward of the body).

§head_cy: f64§head_r: f64§ear_w: f64

Ear geometry: half-width at the base, length, lean (x-offset of the tip), and the gap between the two ear centres at the head.

§ear_len: f64§ear_lean: f64§ear_gap: f64§eye_dx: f64

Eye dot centre (offset from the head centre) + radius.

§eye_dy: f64§eye_r: f64§segments: usize

How many segments to sample each rounded part with (even → symmetric).

Implementations§

Source §

impl Rabbit

Source

pub fn outline(&self) -> Vec<Loop> ⓘ

The rabbit as closed polygon loops, outer silhouette first, then the two ears, then the eye dot. Each loop is a CCW ring in the [-1, 1] box (y up). The 2D renderer fills the body+head as the silhouette, fills the ears on top, and punches the eye as a small dark dot.

Source

pub fn silhouette(&self) -> Vec<Loop> ⓘ

The fillable body silhouette: just the body + head + ears (no eye), the loops a 2D renderer fills as the solid mascot. Returned outer→inner so the renderer can paint them in order (body, head, ears) with one colour.

Source

pub fn eye(&self) -> Loop

The eye dot loop alone (the dark feature drawn on top of the fill).
