A plane cut material for the bevy game engine.
Install the crate.
cargo add bevy_plane_cutuse bevy::prelude::*;
fn main() {
App::new()
.add_plugins(bevy_plane_cut::PlaneCutPlugin)
.run();
}use bevy::{
prelude::*,
color::palettes::basic,
pbr::ExtendedMaterial,
};
use bevy_plane_cut::*;
fn setup(
mut commands: Commands,
mut meshes: ResMut<Assets<Mesh>>,
mut materials: ResMut<Assets<PlaneCutMaterial>>) {
commands.spawn(MaterialMeshBundle {
mesh: meshes.add(Sphere::new(1.0)),
material: materials.add(ExtendedMaterial {
base: StandardMaterial {
base_color: basic::RED.into(),
..default()
},
extension: PlaneCutExt {
plane: Vec4::new(-1.0, 1.0, -2.0, 0.0),
color: Color::linear_rgb(0.0, 0.0, 0.7),
shaded: true,
space: Space::World,
},
}),
..default()
});
}Run the "simple" example like so:
cargo run --example simpleThis will show a red sphere with a light rotating around it and blue plane cut.
simple- A red sphere with a plane cut.simple_screenspace- A red sphere with a plane cut in screen space.moving_cut- A red sphere with a plane cut moving in and out.
simple_deferred- same as simple but using deferred renderer. NOTE: This one does not look right on my macOS machine.deferred- A red sphere rendered with deferred renderer. This has no plane cut at all and it still does not look right. I'm using macOS, so I'd be curious if it looks correct on other platforms.two_cuts- This is a material that has been extended byPlaneCutExttwice. However, it has a bug. Seetwo_cuts.rsexample for more details. PRs welcome!

Clipping a Model with a Plane by Ronja taught me the technique many years ago.

Extending Materials in Bevy 0.12 with Material Extension by Chris Biscardi showed off how cool

Thanks to robtfm who wrote the original extended_material.rs example in bevy.
