Struct FastMarchingMethod 

pub struct FastMarchingMethod {
    pub nx: usize,
    pub ny: usize,
    pub nz: usize,
    pub dx: f64,
    pub dist: Vec<f64>,
    /* private fields */
}

Fast Marching Method SDF solver on a uniform 3D grid.

Given initial interface cells (known SDF values near zero), propagates the signed distance function throughout the grid.

Fields

nx: usize

Grid size.

ny: usize

Grid size.

nz: usize

Grid size.

dx: f64

Grid spacing.

dist: Vec<f64>

Computed signed distances.

Implementations

impl FastMarchingMethod

pub fn new(nx: usize, ny: usize, nz: usize, dx: f64) -> Self

Construct a new FMM solver for a grid of given size and spacing.

pub fn set_known(&mut self, known: &[(usize, f64)])

Set known interface cells from (index, distance) pairs.

pub fn run(&mut self)

Run the FMM to propagate distances from known cells.

pub fn distance_at(&self, ix: usize, iy: usize, iz: usize) -> f64

Get the distance at grid index (ix, iy, iz).
