Struct calcify::ThreeField

pub struct ThreeField<'a> { /* private fields */ }

Three dimensional scalar field

Implementations

impl<'a> ThreeField<'a>

pub fn new(func: &'a dyn Fn(&ThreeVec) -> f64) -> ThreeField<'_>

Returns a new ThreeField

Arguments

• func - &’a dyn Fn(&ThreeVec) -> f64

Example

use calcify::ThreeVec;
use calcify::ThreeField;
 
let g = ThreeField::new(&|tv: &ThreeVec| tv.r());
let g2: ThreeField = 2.0*g;

let test_vec = ThreeVec::new(2.0,2.0,2.0);

assert_eq!(g.loc(2.0,2.0,2.0),test_vec.r());
assert_eq!(g.at(test_vec),test_vec.r());
assert_eq!(g2.loc(2.0,2.0,2.0),2.0*test_vec.r());

pub fn loc(&self, i: f64, j: f64, k: f64) -> f64

Return value of field from three floats.

pub fn at(&self, vec: ThreeVec) -> f64

Return value of field at vector.
