Struct VtkStructuredGrid 

pub struct VtkStructuredGrid {
    pub dims: [usize; 3],
    pub points: Vec<[f64; 3]>,
    pub point_data: Vec<VtkDataArray>,
}

A VTK structured grid (.vts) with explicit point coordinates.

Dimensions are (ni, nj, nk) in index space. Points are ordered with i varying fastest, then j, then k.

Fields

dims: [usize; 3]

Dimensions \[ni, nj, nk\].

points: Vec<[f64; 3]>

3-D coordinates of every point (ordered i,j,k).

point_data: Vec<VtkDataArray>

Per-point data arrays.

Implementations

impl VtkStructuredGrid

pub fn new(ni: usize, nj: usize, nk: usize) -> Self

Create an empty structured grid with the given dimensions.

pub fn n_points(&self) -> usize

Number of points (ni × nj × nk).

pub fn add_point_scalar(&mut self, name: &str, values: Vec<f64>)

Append a per-point scalar field.

pub fn to_vts_string(&self) -> String

Serialise to VTK XML .vts format string.

pub fn uniform( x0: f64, x1: f64, ni: usize, y0: f64, y1: f64, nj: usize, z0: f64, z1: f64, nk: usize, ) -> Self

Build a uniform Cartesian grid covering \[x0,x1\] x \[y0,y1\] x \[z0,z1\].
