Struct MotionVector 

pub struct MotionVector {
    pub dx: f64,
    pub dy: f64,
    pub cost: f64,
}

A motion vector representing displacement of a block.

Fields

dx: f64

Horizontal displacement in pixels.

dy: f64

Vertical displacement in pixels.

cost: f64

Match quality (lower SAD means better match).

Implementations

impl MotionVector

pub fn new(dx: f64, dy: f64, cost: f64) -> Self

Create a new motion vector.

pub fn zero() -> Self

Create a zero motion vector.

pub fn magnitude(&self) -> f64

Compute the magnitude of this motion vector.

pub fn direction(&self) -> f64

Compute the direction angle in radians.

pub fn add(&self, other: &Self) -> Self

Add two motion vectors.

pub fn scale(&self, factor: f64) -> Self

Scale this motion vector by a factor.

Trait Implementations

impl Clone for MotionVector

fn clone(&self) -> MotionVector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MotionVector

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

Formats the value using the given formatter.

impl PartialEq for MotionVector

fn eq(&self, other: &MotionVector) -> 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.
