Implementations

impl Exposure

pub const SUNLIGHT: Self = _

pub const OVERCAST: Self = _

pub const INDOOR: Self = _

pub const BLENDER: Self = _

This value was calibrated to match Blender’s implicit/default exposure as closely as possible. It also happens to be a reasonable default.

See https://github.com/bevyengine/bevy/issues/11577 for details.

pub const EV100_SUNLIGHT: f32 = 15f32

pub const EV100_OVERCAST: f32 = 12f32

pub const EV100_INDOOR: f32 = 7f32

pub const EV100_BLENDER: f32 = 9.6999998f32

This value was calibrated to match Blender’s implicit/default exposure as closely as possible. It also happens to be a reasonable default.

See https://github.com/bevyengine/bevy/issues/11577 for details.

pub fn from_physical_camera( physical_camera_parameters: PhysicalCameraParameters, ) -> Self

pub fn exposure(&self) -> f32

Converts EV100 values to exposure values. https://google.github.io/filament/Filament.md.html#imagingpipeline/physicallybasedcamera/exposure
