Struct LiftedCurve2

pub struct LiftedCurve2 {
    pub curve: Box<Curve3>,
    pub carrier: Carrier,
    pub start: f64,
    pub end: f64,
    pub guide: Vec<DVec2>,
}

A curve in space read in an analytic surface’s parameters: the pcurve at t is the carrier’s parameters of curve’s point at t, so it shares the edge’s parameter exactly. This is the pcurve, on the analytic face, of a section that only the other face’s surface can carry (a B-spline’s section, ADR 0077): the inverse is in closed form for planes, ruled surfaces, spheres and tori.

Angles are defined up to whole turns; guide holds the parameters at evenly spaced t over [start, end], unwrapped along the curve, and a point is read at the turn nearest the guide there. Evaluation lives in axiolid-evaluate, which evaluates the space curve.

Fields

curve: Box<Curve3>

The curve in space.

carrier: Carrier

The surface it is read on.

start: f64

Parameter range the guide covers.

end: f64

End of that range.

guide: Vec<DVec2>

Unwrapped parameters at evenly spaced t from start to end.

Implementations

impl LiftedCurve2

pub fn guide_at(&self, t: f64) -> Option<DVec2>

The guide’s parameters at t, interpolated.

pub fn unwrap_at(&self, t: f64, point: DVec3) -> Option<DVec2>

The carrier’s parameters of a space point, at the turns nearest the guide at t.

pub fn is_finite(&self) -> bool

Whether every number is finite.

Trait Implementations

impl Clone for LiftedCurve2

fn clone(&self) -> LiftedCurve2

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LiftedCurve2

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

Formats the value using the given formatter.

impl PartialEq for LiftedCurve2

fn eq(&self, other: &LiftedCurve2) -> 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.
