Struct LinearExtrusion 

pub struct LinearExtrusion {
    pub profile: Vec<[f64; 2]>,
    pub sweep_vec: [f64; 3],
}

A shape extruded linearly along a vector — a prism swept volume.

The base polygon is defined in the XY plane and the extrusion direction is given by sweep_vec.

Fields

profile: Vec<[f64; 2]>

2-D profile points (X, Y components).

sweep_vec: [f64; 3]

Extrusion vector in 3-D space.

Implementations

impl LinearExtrusion

pub fn new(profile: Vec<[f64; 2]>, sweep_vec: [f64; 3]) -> Self

Create a new linear extrusion.

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

Conservative AABB enclosing the extruded prism.

pub fn volume(&self) -> f64

Approximate volume: profile area × extrusion length.

pub fn profile_area(&self) -> f64

Area of the 2-D profile using the shoelace formula.

pub fn profile_perimeter(&self) -> f64

Perimeter of the 2-D profile.

pub fn surface_area(&self) -> f64

Surface area of the extruded prism.

= 2 * profile_area + perimeter * extrusion_length
