Available on crate feature meshlet only.
Expand description

A mesh that has been pre-processed into multiple small clusters of triangles called meshlets.

A bevy_render::mesh::Mesh can be converted to a MeshletMesh using MeshletMesh::from_mesh when the meshlet_processor cargo feature is enabled. The conversion step is very slow, and is meant to be ran once ahead of time, and not during runtime. This type of mesh is not suitable for dynamically generated geometry.

There are restrictions on the crate::Material functionality that can be used with this type of mesh.

See also super::MaterialMeshletMeshBundle and super::MeshletPlugin.

Fields§

§worst_case_meshlet_triangles: u64

The total amount of triangles summed across all LOD 0 meshlets in the mesh.

§vertex_data: Arc<[u8]>

Raw vertex data bytes for the overall mesh.

§vertex_ids: Arc<[u32]>

Indices into vertex_data.

§indices: Arc<[u8]>

Indices into vertex_ids.

§meshlets: Arc<[Meshlet]>

The list of meshlets making up this mesh.

§bounding_spheres: Arc<[MeshletBoundingSpheres]>

Spherical bounding volumes.

Implementations§

§

impl MeshletMesh

pub fn from_mesh( mesh: &Mesh, ) -> Result<MeshletMesh, MeshToMeshletMeshConversionError>

Process a Mesh to generate a MeshletMesh.

This process is very slow, and should be done ahead of time, and not at runtime.

This function requires the meshlet_processor cargo feature.

The input mesh must:

  1. Use PrimitiveTopology::TriangleList
  2. Use indices
  3. Have the exact following set of vertex attributes: {POSITION, NORMAL, UV_0, TANGENT}
