Struct SpatialHash 

Source 
pub struct SpatialHash { /* private fields */ }
Expand description

A flat 2D spatial hash grid for O(1) proximity queries against road nodes and edges.

Implementations§

Source§

impl SpatialHash

Source

pub fn new(world_width: f32, world_depth: f32, cell_size: f32) -> Self

Creates a new spatial hash covering a world_width × world_depth area with cells of the given size. If the resulting grid would exceed MAX_CELLS, cell_size is automatically increased to fit.

Source

pub fn insert_node(&mut self, id: NodeId, pos: Vec2)

Registers a node in the cell containing pos.

Source

pub fn remove_edge(&mut self, id: EdgeId, start: Vec2, end: Vec2)

Removes an edge from every cell it was registered in.

Source

pub fn insert_edge(&mut self, id: EdgeId, start: Vec2, end: Vec2)

Registers an edge in every cell its axis-aligned bounding box overlaps.
