Struct Revolved 

pub struct Revolved {
    pub frame: Frame,
    pub profile: Profile,
    pub on_axis: f64,
}

A surface swept by a profile turning about the z of frame: the profile lies in the half plane of frame.x at angle 0.

Fields

frame: Frame

profile: Profile

on_axis: f64

How close to the axis a point is on it, and has no angle: the file’s uncertainty.

Implementations

impl Revolved

pub fn chart(&self, p: P3) -> (Option<f64>, f64)

The angle of p about the axis, and its profile parameter where the profile is analytic — None for the angle of a point on the axis, which has none.

pub fn iso_line(&self, shape: &Shape, uncertainty: f64) -> bool

Whether a curve of shape lying on this surface runs along a line of one parameter of its patches, to within uncertainty, the file’s statement of which places are one: a circle about its axis is a parallel, at one profile parameter, and a line in a plane through its axis a meridian, at one angle. On a patch its pcurve is then straight.

pub fn past_axis(&self, p: P3) -> Option<f64>

For a circle crossing the axis, how much nearer p lies to the sheet its arc past the axis turns into than to the one its arc on this side does: positive where p is on the sheet past the axis.

pub fn mirrored(&self) -> Revolved

The sheet the arc of a circle crossing the axis past it turns into, as a surface of its own: the circle mirrored in the axis, turned on this side. Its profile parameter runs the other way round the circle, so its normal is the other way round to the file’s.

pub fn v_is_angle(&self) -> bool

Whether the profile’s parameter v goes once round, as a torus’ does: then it is an angle too.

pub fn poles(&self) -> Vec<f64>

Where the profile meets the axis, by its parameter: the poles of the surface.

pub fn profile_point(&self, v: f64) -> P3

The profile’s point at v, in the half plane at angle 0.

pub fn profile_curve(&self, v0: f64, v1: f64) -> GeopResult<NurbCurve3D>

The profile from v0 to v1 as a curve, in the half plane at angle 0 — the whole curve, for a profile that is one.

pub fn parallel(&self, v: f64, from: f64, to: f64) -> GeopResult<NurbCurve3D>

The parallel at the profile parameter v — the circle about the axis the profile’s point there turns along — from the angle from counter-clockwise about the axis to to: all the way round where they are one.

pub fn axis(&self) -> GeopResult<Axis>

pub fn patch( &self, from: f64, to: f64, v0: f64, v1: f64, ) -> GeopResult<NurbSurface3D>

The surface between the angles from and to and, where the profile is analytic, the profile parameters v0 and v1.

pub fn iso(&self) -> Shape

What a parallel or a meridian of it is, as an edge’s Shape.

pub fn turn(&self, angle: f64) -> GeopResult<Pose>

The motion turning by angle radians about the axis.
