Struct ParametricSurface

pub struct ParametricSurface {
    pub f1: Function,
    pub f2: Function,
    pub f3: Function,
}

Special function of R^2→R^3

Parametric Surface

Parametric surfaces are part of a Surface, but you can create one by itself with the parametric_surface! macro. They are composed of three scalar two-dimensional functions, and they behave like 2D functions, except they return a 3D vector.
These also implement display, and have a .ddu(f64,f64) and .ddv(f64,f64) that returns the partial derivative vectors.

Examples

use vector_calculus::*;
let p:ParametricSurface = parametric_surface!(u, v, u.powi(2)*v, u+v, v*u);
println!("p(u,v) = {}", p);
assert_eq!(p(1., 2.), vector!(2, 3, 2));

Fields

f1: Function

f2: Function

f3: Function
