Enum ToneMapping

pub enum ToneMapping {
    None = 0,
    Reinhard = 1,
    Aces = 2,
    Filmic = 3,
}

Tone mapping is the process of mapping HDR color values computed with physical based rendering in the range [0,∞) into LDR values that can be displayed on the screen in the range [0,1].

Variants

None = 0

No tone mapping. Use this if you are rendering into an intermediate render target, ie. this is not the final render pass that renders into the screen.

Implementations

impl ToneMapping

pub fn fragment_shader_source() -> &'static str

Returns the fragment shader source for applying the specified tone mapping in a shader.

pub fn use_uniforms(&self, program: &Program)

Sends the uniform data needed to apply this tone mapping to the fragment shader.

Trait Implementations

impl Clone for ToneMapping

fn clone(&self) -> ToneMapping

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ToneMapping

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

Formats the value using the given formatter.

impl Default for ToneMapping

fn default() -> ToneMapping

Returns the “default value” for a type.

impl Ord for ToneMapping

fn cmp(&self, other: &ToneMapping) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ToneMapping

fn eq(&self, other: &ToneMapping) -> 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 ToneMapping

fn partial_cmp(&self, other: &ToneMapping) -> 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.
