Struct PySpatialHash 

pub struct PySpatialHash {
    pub cell_size: f64,
    pub points: Vec<[f64; 3]>,
    /* private fields */
}

A spatial hash map for fast point proximity queries.

Fields

cell_size: f64

Cell size determines resolution of the hash grid.

points: Vec<[f64; 3]>

Points indexed by ID.

Implementations

impl PySpatialHash

pub fn new(cell_size: f64) -> Self

Create a new spatial hash with the given cell size.

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

Insert a point and return its ID.

pub fn remove(&mut self, id: usize)

Remove a point by ID (marks its cell entry as removed).

pub fn query(&self, p: [f64; 3]) -> Vec<usize>

Query all points in the cell containing p.

pub fn sphere_query(&self, center: [f64; 3], radius: f64) -> Vec<usize>

Query all points within a sphere of the given radius around center.
