Struct RotationalSweep 

pub struct RotationalSweep {
    pub profile: Vec<[f64; 2]>,
    pub segments: usize,
}

A rotational sweep (lathe) — rotate a 2-D profile around the Y axis.

The profile is specified as (r, y) pairs where r is the radial distance from the Y axis. The resulting solid of revolution is discretised into segments triangular strips.

Fields

profile: Vec<[f64; 2]>

Profile: (radius, height) pairs.

segments: usize

Number of angular segments (resolution).

Implementations

impl RotationalSweep

pub fn new(profile: Vec<[f64; 2]>, segments: usize) -> Self

Create a new rotational sweep.

pub fn aabb(&self) -> ([f64; 3], [f64; 3])

Conservative AABB.

pub fn volume(&self) -> f64

Approximate volume via the disk/washer method (trapezoidal integration).

pub fn lateral_surface_area(&self) -> f64

Approximate surface area (lateral only, no caps).

pub fn vertices(&self) -> Vec<[f64; 3]>

Generate vertex positions for the mesh.

Returns a Vec of [f64; 3] positions.
