Struct Shutter 

pub struct Shutter {
    pub range: Range<Time>,
    pub opening: Range<Time>,
}

Shutter timing for motion blur sampling.

A Shutter struct defines a time range and opening pattern for generating motion blur samples. The opening function determines the weight of samples at different times within the shutter interval.

Fields

range: Range<Time>

The overall time range for sampling.

opening: Range<Time>

The time range during which the shutter is opening.

Implementations

impl Shutter

pub fn opening(&self, pos: Time) -> f32

Evaluate the shutter at time.

Returns a value between 0.0 and 1.0 that represents the shutter’s opening at time.

pub fn evaluate(&self, pos: f32) -> Time

pub fn center(&self) -> Time

Returns the center of the shutter.

Trait Implementations

impl Clone for Shutter

fn clone(&self) -> Shutter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Shutter

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

Formats the value using the given formatter.

impl Default for Shutter

fn default() -> Shutter

Returns the “default value” for a type.

impl Hash for Shutter

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 Shutter

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