A 2D or 3D mesh (bevy::render::mesh::Mesh) generated from a
single-variable function f(f32) -> f32.
We have one math function that generates a half squircle and one that generates a half circle.
``` fn squircle(x: f32) -> f32 { (1.0 - (x).abs().powf(4.0)).powf(0.25) }
fn circle(x: f32) -> f32 { (1.0 - x.powf(2.0)).powf(0.5) } ```
commands.spawn(PbrBundle {
mesh: meshes.add(
SingleVariableFunctionMesh {
f: squircle, // or circle
relative_height: 0.0,
..default()
}
.into(),
),
material: materials.add(StandardMaterial::default()),
transform: Transform::from_xyz(-2.5, 1.0, 0.0),
..default()
});
commands.spawn(PbrBundle {
mesh: meshes.add(
SingleVariableFunctionMesh {
f: squircle, // or circle
relative_height: 0.2,
..default()
}
.into(),
),
material: materials.add(StandardMaterial::default()),
transform: Transform::from_xyz(0.0, 1.0, 0.0),
..default()
