Struct ProfileLoop 

pub struct ProfileLoop {
    pub edges: Vec<ProfileEdge>,
}

A closed chain of curves, each ending where the next starts.

Fields

edges: Vec<ProfileEdge>

Implementations

impl ProfileLoop

pub fn reversed(&self) -> ProfileLoop

The same loop traversed the other way.

pub fn to_nurbs<S: Scalar>( &self, sketch: &Sketch, positions: &Positions, ) -> GeopResult<Vec<ProfilePiece<S>>>

The loop as NURBS pieces, each on the domain [0, 1], each starting exactly where the previous one ends, with the sketch’s points placed at positions (the sketch’s own positions, or a rigid, orientation-preserving motion of them).

Arcs are split into pieces of at most a quarter turn — a rational quadratic’s middle weight cos(sweep / 2) must stay positive — and circles into four quarters. A loop of a single piece (a closed spline) is split in two, so every loop has at least two joints. Each piece records which sketch curve it is part of and which joints it runs between (see ProfilePiece).

Also used for an open chain (a revolve profile): the pieces then simply don’t close up, and the last one’s end is the chain’s end.

pub fn polyline(&self, sketch: &Sketch, positions: &Positions) -> Vec<[f64; 2]>

A dense polyline along the loop (for nesting tests and display).

Trait Implementations

impl Clone for ProfileLoop

fn clone(&self) -> ProfileLoop

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProfileLoop

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

Formats the value using the given formatter.

impl Eq for ProfileLoop

impl PartialEq for ProfileLoop

fn eq(&self, other: &ProfileLoop) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
