Struct Rim 

pub struct Rim {
    pub vertices: Vec<u32>,
    pub vector_area: Vector,
    pub centre: Point,
    pub flatness: f64,
    pub closed: bool,
}

Where a mesh is open: a chain of edges each of which only one triangle uses.

Fields

vertices: Vec<u32>

The vertices in the order the mesh’s triangles traverse the rim; the last joins the first where the rim is closed.

vector_area: Vector

The vector area of the face that would close the rim, wound the way the mesh is: the sum of area × normal over any surface spanning it, which is the same for every one. Its length is the opening’s area where the rim is planar, and it points out of the mesh through the opening, so it can vote as the face that would close it.

centre: Point

The rim’s centroid, by length.

flatness: f64

The greatest distance of a rim vertex from the plane through the centre square to the vector area: zero for a planar rim.

closed: bool

Whether the chain returns to where it started. A rim through a vertex where the triangles round it do not meet in one fan breaks there, and its vector area is the chain’s closed by its chord.
