Struct QuadField 

pub struct QuadField { /* private fields */ }

A plane of columns × rows squares drawn on every frame. At rest it lies like a floor that waves, lit in the accent and lifting under the pointer; as the scroll progresses through its ScrollRange it stands up and becomes the picture its function paints, one color per square. Nothing is rebuilt or laid out while it moves. Under reduced motion the floor stands still.

use ravenrs_core::Color;
use ravenrs_widgets::QuadField;

// A blue square on a dark screen.
let field = QuadField::new(96, 54, |u, v, _time| {
    if (0.4..0.6).contains(&u) && (0.4..0.6).contains(&v) { Color::hex(0x4c66ee) } else { Color::hex(0x12151c) }
})
.height(720.0);

Implementations

impl QuadField

pub fn new( columns: u16, rows: u16, picture: impl Fn(f32, f32, f64) -> Color + 'static, ) -> QuadField

A field of columns × rows squares forming the picture picture(u, v, seconds), where u and v run from 0 to 1 across and down.

pub fn height(self, height: f32) -> QuadField

The height of the field (600 by default); it fills the width it is given.

pub fn range(self, range: ScrollRange) -> QuadField

The stretch of scrolling over which it stands up (ScrollRange::Scene by default: the scene around it, or its own pass across the view outside one).
