Enum ncollide2d::shape::FeatureId

source · [−]

pub enum FeatureId {
    Vertex(usize),
    Face(usize),
    Unknown,
}

Expand description

An identifier of a feature of a convex polyhedron.

This identifier is shape-dependent and is seach that it allows an efficient retrieval of the geometric information of the feature.

Variants

`Vertex(usize)`

Shape-dependent identifier of a vertex.

`Face(usize)`

Shape-dependent identifier of a face.

`Unknown`

Unknown identifier.
