Struct Attenuation

pub struct Attenuation {
    pub constant: f32,
    pub linear: f32,
    pub quadratic: f32,
}

Specifies how the intensity of a light fades over distance. The light intensity is scaled by 1 / max(1, constant + distance * linear + distance * distance * quadratic).

Fields

constant: f32

Constant attenuation factor.

linear: f32

Linear attenuation factor.

quadratic: f32

Quadratic attenuation factor.

Trait Implementations

impl Clone for Attenuation

fn clone(&self) -> Attenuation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Attenuation

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

Formats the value using the given formatter.

impl Default for Attenuation

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Attenuation

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

impl PartialOrd for Attenuation

fn partial_cmp(&self, other: &Attenuation) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
