    pub vids: [u32; 4],
    pub eids: [u32; 4],
    pub fid: u32,
    pub num_vertices: usize,
}

A polygonal feature representing the local polygonal approximation of a vertex, face, or edge of a convex shape.

Fields

vertices: [Point<Real>; 4]

Up to four vertices forming this polygonal feature.

vids: [u32; 4]

The feature IDs of this polygon's vertices.

eids: [u32; 4]

The feature IDs of this polygon's edges.

fid: u32

The feature ID of this polygonal feature.

num_vertices: usize

The number of vertices on this polygon (must be <= 4).
