Struct HexagonalSearch 

pub struct HexagonalSearch {
    pub inner: [(i32, i32); 6],
    pub outer: [(i32, i32); 6],
    pub max_iterations: u32,
}

Hexagonal search pattern (HEX) for motion estimation.

A 6-point pattern inspired by the H.264 HEX search:

    *   *
  *   O   *
    *   *

Hexagonal patterns often outperform diamond patterns for complex motion because they cover 6 equidistant directions simultaneously.

Fields

inner: [(i32, i32); 6]

Inner hex (6 points, radius ≈ 2).

outer: [(i32, i32); 6]

Outer hex (6 points, radius ≈ 4).

max_iterations: u32

Maximum iterations before refinement.

Implementations

impl HexagonalSearch

pub const INNER_PATTERN: [(i32, i32); 6]

Standard inner hexagon offsets (radius ≈ 2).

pub const OUTER_PATTERN: [(i32, i32); 6]

Standard outer hexagon offsets (radius ≈ 4).

pub const fn new() -> Self

Create a new hexagonal search.

pub const fn max_iterations(self, max: u32) -> Self

Set maximum iterations.
