Function truck_modeling::builder::rsweep

pub fn rsweep<T: ClosedSweep<Point3, NURBSCurve, NURBSSurface>>(
    elem: &T, 
    origin: Point3, 
    axis: Vector3, 
    angle: Rad<f64>
) -> T::Swept

Sweeps a vertex, an edge, a wire, a face, or a shell by the rotation.

Details

If the absolute value of angle is more than 2π rad, then the result is closed shape. For example, the result of sweeping a disk is a bent cylinder if angle is less than 2π rad and a solid torus if angle is more than 2π rad.

Examples

// Torus
use truck_modeling::*;
const PI: Rad<f64> = Rad(std::f64::consts::PI);

let v: Vertex = builder::vertex(Point3::new(3.0, 0.0, 0.0));
let circle: Wire = builder::rsweep(&v, Point3::new(2.0, 0.0, 0.0), Vector3::unit_z(), PI * 2.0);
let torus: Shell = builder::rsweep(&circle, Point3::origin(), Vector3::unit_y(), PI * 2.0);
let solid: Solid = Solid::new(vec![torus]);

// Modeling a pipe.
use truck_modeling::*;
const PI: Rad<f64> = Rad(std::f64::consts::PI);

// Creates the base circle
let v: Vertex = builder::vertex(Point3::new(1.0, 0.0, 4.0));
let circle: Wire = builder::rsweep(&v, Point3::new(2.0, 0.0, 4.0), -Vector3::unit_z(), PI * 2.0);

// the result shell of the pipe.
let mut pipe: Shell = Shell::new();

// Draw the first line pipe
let mut first_line_part: Shell = builder::tsweep(&circle, Vector3::new(0.0, 0.0, -4.0));
pipe.append(&mut first_line_part);

// Get the new wire
let boundaries: Vec<Wire> = pipe.extract_boundaries();
let another_circle: Wire = boundaries.into_iter().find(|wire| wire != &circle).unwrap().inverse();

// Draw the bent part
let mut bend_part: Shell = builder::rsweep(
    &another_circle,
    Point3::origin(),
    Vector3::unit_y(),
    PI / 2.0,
);
pipe.append(&mut bend_part);

// Get the new wire
let boundaries: Vec<Wire> = pipe.extract_boundaries();
let another_circle: Wire = boundaries.into_iter().find(|wire| wire != &circle).unwrap().inverse();

// Draw the second line pipe
let mut second_line_part: Shell = builder::tsweep(&another_circle, Vector3::new(-4.0, 0.0, 0.0));
pipe.append(&mut second_line_part);

assert_eq!(pipe.shell_condition(), ShellCondition::Oriented);
