pub fn regular_octree_with_bounding_box<T: RealType>(
    particles: ArrayView2<'_, T>,
    max_level: usize,
    origin: [f64; 3],
    diameter: [f64; 3],
) -> Octree<'_, T>

Create a regular Octree with given bounding box.

Returns a RegularOctree struct describing a regular octree.

Arguments

• particles - A (3, N) array of particles of type f32 or f64.
• max_level - The maximum level of the tree. origin - The origin of the bounding box. diameter - The diameter of the bounding box in each dimension.
