Struct LoftSurface 

Source 
pub struct LoftSurface {
    pub curve_a: BezierCurve,
    pub curve_b: BezierCurve,
}
Expand description

A lofted surface interpolated between two Bezier curves.

For parameter (u, v), the surface point is: lerp( curve_a.evaluate(u), curve_b.evaluate(u), v ).

Fields§

§curve_a: BezierCurve

The “bottom” profile curve (at v = 0).

§curve_b: BezierCurve

The “top” profile curve (at v = 1).

Implementations§

Source§

impl LoftSurface

Source

pub fn new(curve_a: BezierCurve, curve_b: BezierCurve) -> Self

Create a new loft surface from two Bezier curves.

Source

pub fn evaluate(&self, u: f64, v: f64) -> [f64; 3]

Evaluate the lofted surface at (u, v) ∈ [0, 1]².

Source

pub fn normal(&self, u: f64, v: f64) -> [f64; 3]

Surface normal at (u, v) via finite differences: ∂P/∂u × ∂P/∂v.

Source

pub fn sample_grid(&self, nu: usize, nv: usize) -> Vec<Vec<[f64; 3]>>

Sample the surface as a nu × nv grid, returned row-major.
