SpatialIndex

Struct SpatialIndex 

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

Spatial index wrapping an octree for pre-filtering graph traversal candidates.

Build once from the node array, reuse across multiple algorithm calls. Provides O(log n) spatial queries instead of O(n) brute-force containment checks.

Implementations§

Source§

impl SpatialIndex

Source

pub fn from_nodes(nodes: &[GraphNode4D]) -> Self

Build a spatial index from a slice of graph nodes.

Source

pub fn prefilter(&self, region: &SpatialRegion) -> HashSet<u64>

Pre-filter node IDs matching the spatial region using the octree.

Returns a HashSet of node IDs that fall within the region. Use this to populate TraversalContext4D::spatial_candidates.
