Struct VolumeData 

Source 
pub struct VolumeData {
    pub data: Vec<f32>,
    pub dims: [u32; 3],
    pub origin: [f32; 3],
    pub spacing: [f32; 3],
}
Expand description

A structured 3D scalar field on a regular grid.

Fields§

§data: Vec<f32>

Flattened scalar values in x-fastest order: index = x + y*nx + z*nx*ny.

§dims: [u32; 3]

Grid dimensions [nx, ny, nz].

§origin: [f32; 3]

World-space origin of the grid corner (0, 0, 0).

§spacing: [f32; 3]

Cell size in each axis direction.

Implementations§

Source§

impl VolumeData

Source

pub fn in_bounds(&self, ix: u32, iy: u32, iz: u32) -> bool

Source

pub fn sample(&self, ix: u32, iy: u32, iz: u32) -> f32

Read the scalar value at grid point (ix, iy, iz).

§Panics

Panics if the index is out of bounds.
