Usage
System setup
Add the plugin to your app:
use bevy::prelude::*;
use bevy_points::prelude::*;
fn main() {
App::new()
.add_plugin(PointsPlugin);
}
Apply a component to a MaterialMeshBundle
fn setup(
mut commands: Commands,
mut meshes: ResMut<Assets<Mesh>>,
mut materials: ResMut<Assets<PointsMaterial>>,
) {
let n = 320; // # of points
let h = 3.0; // spiral height
commands.spawn(MaterialMeshBundle {
mesh: meshes.add(
PointsMesh::from_iter((0..n).map(|i| {
let t01 = (i as f32) / ((n - 1) as f32);
let r = t01 * TAU * 4.0; // spiral fineness
Vec3::new(r.cos(), (t01 - 0.5) * h, r.sin())
}))
.into(),
),
material: materials.add(PointsMaterial {
settings: PointsShaderSettings {
point_size: 20., // Defines the size of the points.
..Default::default()
},
perspective: true, // Specify whether points' size is attenuated by the camera depth.
circle: true, // Specify whether the shape of points is circular or rectangular.
..Default::default()
}),
..Default::default()
});
commands.spawn(MaterialMeshBundle {
mesh: meshes.add(
// Mesh can be converted to PointsMesh.
PointsMesh::from(Mesh::from(shape::Icosphere::default()))
.into()
),
material: materials.add(PointsMaterial {
settings: PointsShaderSettings {
color: Color::BLUE,
opacity: 0.5,
..Default::default()
},
alpha_mode: AlphaMode::Blend,
