Struct TangentChain 

pub struct TangentChain {
    pub links: Vec<Link>,
    pub closed: bool,
}

The edges blended as one: a tangent chain (see the module docs), in the order it runs, around to the first again if closed.

Fields

links: Vec<Link>

closed: bool

Implementations

impl TangentChain

pub fn vertices(&self, model: &Model) -> GeopResult<Vec<VertexId>>

The chain’s vertices in order: where each link starts, and — for an open chain — where the last one ends.

pub fn first(&self) -> GeopResult<&Link>

Its first link.

pub fn last(&self) -> GeopResult<&Link>

Its last link.

pub fn edges(&self) -> Vec<EdgeId>

pub fn ends( &self, model: &Model, ) -> GeopResult<[(VertexId, [FaceId; 2], Vector3); 2]>

An open chain’s start and end: at each its vertex, the faces either side of the link there, and the unit direction out of the chain.

Trait Implementations

impl Clone for TangentChain

fn clone(&self) -> TangentChain

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TangentChain

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
