Struct ExtrusionSurface 

pub struct ExtrusionSurface { /* private fields */ }

A curve swept along a direction.

u is the generating curve’s parameter; v is the distance swept.

Implementations

impl ExtrusionSurface

pub fn new( curve: Curve, direction: Direction, distance: f64, ) -> OgeomResult<Self>

Sweep curve along direction over [0, distance].

Errors

OgeomError::Construction if distance is not finite and positive.

pub fn over( curve: Curve, direction: Direction, extent: (f64, f64), ) -> OgeomResult<Self>

Sweep curve along direction over an explicit window of the sweep parameter: a file’s extrusion, unbounded either way, is given the window its faces reach.

Errors

OgeomError::Construction if the window is not finite and increasing.

pub const fn curve(&self) -> &Curve

The generating curve.

pub const fn direction(&self) -> Direction

The sweep direction.

Trait Implementations

impl Clone for ExtrusionSurface

fn clone(&self) -> ExtrusionSurface

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExtrusionSurface

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

Formats the value using the given formatter.

impl From<ExtrusionSurface> for SurfaceGeometry

fn from(s: ExtrusionSurface) -> Self

Converts to this type from the input type.

impl PartialEq for ExtrusionSurface

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

impl StructuralPartialEq for ExtrusionSurface

impl Surface for ExtrusionSurface

fn domain(&self) -> ((f64, f64), (f64, f64))

The u and v parameter intervals.

fn point_at(&self, u: f64, v: f64, tol: Tolerances) -> OgeomResult<Point>

The point at (u, v).

What kind of surface this is.

fn continuity(&self) -> Continuity

How smooth the surface is across its domain.

fn is_closed_u(&self, tol: Tolerances) -> bool

fn parameter_outside( &self, t: f64, a: f64, b: f64, periodic: bool, across: bool, tol: Tolerances, ) -> OgeomResult<f64>

A parameter outside its domain, or on a periodic direction: wrapped where the direction repeats or closes on itself, refused otherwise.
