Struct HeightGrid

pub struct HeightGrid {
    pub origin_x: f64,
    pub origin_y: f64,
    pub dx: f64,
    pub dy: f64,
    pub ncols: usize,
    pub nrows: usize,
    pub heights: Vec<f64>,
}

Expand description

Terrain heights on an axis-aligned, uniform grid in metres. Row-major: heights[i * ncols + j] is column j (east), row i (north). Position y is up; the grid lies in the x–z plane.

Fields§

§origin_x: f64

Frame-x of the first column centre.

§origin_y: f64

Frame-z of the first row centre.

§dx: f64

Column spacing, metres.

§dy: f64

Row spacing, metres.

§ncols: usize

Number of columns (east).

§nrows: usize

Number of rows (north).

§heights: Vec<f64>

Row-major height samples, ncols * nrows.

Implementations§

impl HeightGrid

pub fn new( origin_x: f64, origin_y: f64, dx: f64, dy: f64, ncols: usize, nrows: usize, heights: Vec<f64>, ) -> Result<Self>

Build and validate a grid.

pub fn height_at(&self, x: f64, z: f64) -> f64

Terrain height at a horizontal position, bilinear between samples; clamps at the grid edges.

pub fn from_ascii(text: &str) -> Result<Self>

A grid from an ASCII ESRI .asc raster (projected, metres): header ncols/nrows/xllcorner/yllcorner/cellsize, then row-major heights (north-to-south, west-to-east).
