Fields

nx: usize

Number of grid cells along X.

ny: usize

Number of cells along Y.

nz: usize

Number of cells along Z.

origin: [f64; 3]

World-space coordinates of cell (0,0,0).

spacing: f64

Uniform voxel spacing.

data: Vec<f64>

Flat SDF samples in (z, y, x) major order.

Implementations

impl SdfGrid

pub fn new( nx: usize, ny: usize, nz: usize, origin: [f64; 3], spacing: f64, ) -> Self

Create an empty grid of given resolution and spacing.

pub fn from_sdf<S: Sdf>( sdf: &S, nx: usize, ny: usize, nz: usize, origin: [f64; 3], spacing: f64, ) -> Self

Sample an SDF and fill the grid.

pub fn cell_center(&self, ix: usize, iy: usize, iz: usize) -> [f64; 3]

World-space position of cell centre (ix, iy, iz).

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

Get the SDF value at integer index (ix, iy, iz).

pub fn set(&mut self, ix: usize, iy: usize, iz: usize, v: f64)

Set the SDF value at integer index (ix, iy, iz).

pub fn interpolate(&self, p: [f64; 3]) -> f64

Trilinearly interpolate the SDF at world-space point p.

pub fn dilate(&mut self, delta: f64)

Apply morphological dilation (grow surface by delta).

pub fn erode(&mut self, delta: f64)

Apply morphological erosion (shrink surface by delta).
