Enum fyrox::scene::camera::Exposure

pub enum Exposure {
    Auto {
        key_value: f32,
        min_luminance: f32,
        max_luminance: f32,
    },
    Manual(f32),
}

Exposure is a parameter that describes how many light should be collected for one frame. The higher the value, the more brighter the final frame will be and vice versa.

Variants

Auto

Fields

key_value: f32

A key value in the formula above. Default is 0.01556.

min_luminance: f32

A min luminance value in the formula above. Default is 0.00778.

max_luminance: f32

A max luminance value in the formula above. Default is 64.0.

Automatic exposure based on the frame luminance. High luminance values will result in lower exposure levels and vice versa. This is default option.

Equation

exposure = key_value / clamp(avg_luminance, min_luminance, max_luminance)

Manual(f32)

Specific exposure level. To “disable” any HDR effects use std::f32::consts::E as a value.

Trait Implementations

impl AsRef<str> for Exposure

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Exposure

fn clone(&self) -> Exposure

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Exposure

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

Formats the value using the given formatter.

impl Default for Exposure

fn default() -> Self

Returns the “default value” for a type.

impl FromStr for Exposure

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Exposure, <Self as FromStr>::Err>

Parses a string s to return a value of this type.

impl PartialEq for Exposure

fn eq(&self, other: &Exposure) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
