valora
A declarative generative art toolkit!
Here's a demo. (Code below)
See some actual pieces I've made with it here.
````rust
extern crate valora;
use palette::;
use rand::StdRng;
use valora::;
struct Circle {
radius: f32,
count: usize,
}
impl Sketch for Circle {
fn sketch(&self, ctx: &SketchContext, mut rng: StdRng) -> Result {
let dotgen = |c: Colorer| {
move |p: Point| Mesh { src: Ellipse::circle(p, self.radius), colorer: c.clone() }
};
let dots: Vec>> = [Colorer::from(Colora::rgb(1.0, 0.0, 0.0, 0.7)),
Colorer::blue()]
.intoiter()
.flatmap(|c| {
sparkles(self.count, &Rect::frame(), &mut rng)
.intoiter()
.map(dotgen(c.clone()))
})
.enumerate()
.map(|(i, mesh)| {
Tween::from(mesh).animscale(1.0,
1.5,
Interpolation::Oscillation {
oscillation: Oscillation::Sine,
start: i,
period: 100,
})
})
.collect();
Ok(Composition::new()
.add(Mesh { src: Rect::frame(), colorer: Colorer::black() })
.add(dots))
}
}
fn main() {
sketch(SketchCfg { size: 500, rootframefilename: Some(String::from("circle")), seed: None },
Circle { radius: 0.05, count: 25 })
.expect("sketch");
}
