Implementations§

Source§

impl Octree

Source

pub fn new(points: &ArrayView2<'_, f64>) -> SpatialResult<Self>

Create a new octree from a set of 3D points

§Arguments
  • points - An array of 3D points
§Returns

A new Octree containing the points

§Errors

Returns an error if the points array is empty or if points don’t have 3 dimensions

Source

pub fn query_nearest( &self, query: &ArrayView1<'_, f64>, k: usize, ) -> SpatialResult<(Vec<usize>, Vec<f64>)>

Query the k nearest neighbors to a given point

§Arguments
  • query - The query point
  • k - The number of nearest neighbors to find
§Returns

A tuple of (indices, distances) where:

  • indices: Indices of the k nearest points in the original data
  • distances: Squared distances to those points
§Errors

Returns an error if the query point doesn’t have 3 dimensions or if k is 0

Source

pub fn query_radius( &self, query: &ArrayView1<'_, f64>, radius: f64, ) -> SpatialResult<(Vec<usize>, Vec<f64>)>

Query all points within a given radius of a point

§Arguments
  • query - The query point
  • radius - The search radius
§Returns

A tuple of (indices, distances) where:

  • indices: Indices of the points within the radius in the original data
  • distances: Squared distances to those points
§Errors

Returns an error if the query point doesn’t have 3 dimensions or if radius is negative

Source

pub fn check_collision( &self, other_points: &ArrayView2<'_, f64>, collision_threshold: f64, ) -> SpatialResult<bool>

Check for collisions between two objects represented by point clouds

§Arguments
  • other_points - Points of the other object
  • collision_threshold - Maximum distance for points to be considered colliding
§Returns

True if any point in other_points is within collision_threshold of any point in this octree

§Errors

Returns an error if other_points doesn’t have 3 dimensions or if collision_threshold is negative

Source

pub fn size(&self) -> usize

Get the total number of points in the octree

§Returns

The number of points

Source

pub fn bounds(&self) -> Option<BoundingBox>

Get the bounding box of the octree

§Returns

The bounding box of the entire octree, or None if the tree is empty

Source

pub fn max_depth(&self) -> usize

Get the maximum depth of the octree

§Returns

The maximum depth of the tree
