Enum Geometry 

pub enum Geometry {
    None,
    PerPrimitive,
    PerVertex,
}

What a component’s value holds of its entity’s mesh (Component::GEOMETRY): whether an edit of the primitives or vertices must carry it along. A component holding geometry of its own (core.mesh, core.mesh_file, a source model a reader keeps beside it) describes no other component’s primitives: Geometry::None.

Variants

None

Nothing per primitive or vertex of its entity’s mesh: kept as it is whatever an edit does to them.

PerPrimitive

Something per primitive of its entity’s mesh (a material per primitive, provenance per part): it implements Component::remap_primitives, goes with the mesh (World::remove_mesh), and an edit that rebuilds the primitives refuses it when it does not answer.

PerVertex

Something per vertex of its entity’s mesh primitives (and so per primitive): as Geometry::PerPrimitive, and it implements Component::remap_vertices too.

Implementations

impl Geometry

pub fn describes_mesh(self) -> bool

Whether the value describes its entity’s mesh, so it goes when the mesh does.

Trait Implementations

impl Clone for Geometry

fn clone(&self) -> Self
