Struct VoxelKey 

pub struct VoxelKey {
    pub level: i32,
    pub x: i32,
    pub y: i32,
    pub z: i32,
}

Octree node key: (level, x, y, z).

All fields are i32 to match the COPC wire format. level is always non-negative in practice; x, y, z are signed per the spec.

Fields

level: i32

Octree depth (0 = root).

x: i32

X coordinate at this level.

y: i32

Y coordinate at this level.

z: i32

Z coordinate at this level.

Implementations

impl VoxelKey

pub const ROOT: VoxelKey

The root octree node.

pub fn parent(&self) -> Option<VoxelKey>

Return the parent key, or None for the root node.

pub fn child(&self, dir: u8) -> VoxelKey

Return the child key in the given octant direction (0–7).

pub fn children(&self) -> [VoxelKey; 8]

Return all eight child keys.

pub fn bounds(&self, root_bounds: &Aabb) -> Aabb

Compute the spatial bounding box of this node given the root octree bounds.

Trait Implementations

impl Clone for VoxelKey

fn clone(&self) -> VoxelKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VoxelKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for VoxelKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for VoxelKey

fn eq(&self, other: &VoxelKey) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
