This crate provides a Bevy plugin for drawing outlines around meshes using the vertex extrusion and jump flood methods.

[dependencies]
bevy_mod_outline = "0.10"

A rotating cube and torus with opaque and transparent outlines.

cargo run --example shapes

Multiple intersecting meshes sharing an outline plane. The outline stencil is offset to create a gap between the object and its outline.

cargo run --example pieces

Many instances of the same mesh, with two different outline configurations, flying towards the camera.

cargo run --example flying_objects

An outlined torus viewed through four cameras with different combinations of render layers enabled.

cargo run --example render_layers

An animated jointed glTF model with an outline.

cargo run --example animated_fox

A glTF model with pre-baked outline normals.

cargo run --example hollow

An animated morphing glTF model with an outline.

cargo run --example morph_targets

A pair of spheres, one outlined, with a UI for selecting different anti-aliasing modes.

cargo run --example ui_aa

An outlined non-manifold shape, with a UI for selecting different outlining methods and shapes.

cargo run --example ui_mode

An emissive sphere orbits another sphere, with outlines and HDR bloom post-processing.

cargo run --example bloom

A flat square with a pulsing jump-flood outline masked by a checkerboard alpha pattern.

cargo run --example alpha_mask

A set of shapes which can be selected by (shift-)clicking on them.

cargo run --example picking

• flood (default) Enable support for the jump flood algorithm.
• interpolation (default) - Define Lerp trait impls using the interpolation crate.
• reflect (default) Define Reflect trait impls for the components.
• scene (default) Enable the AsyncSceneInheritOutline component.
