pub struct Preetham;

Expand description

Simplified Preetham sky model.

Implementations§

Source §

impl Preetham

Source

pub fn zenith_luminance(turbidity: f32, theta_s: f32) -> f32

Zenith luminance (kcd/m²) given turbidity t and sun elevation theta_s (radians).

Source

pub fn sky_luminance(view_dir: Vec3, sun_dir: Vec3, turbidity: f32) -> Vec3

Compute sky luminance (Y, x, y in Yxy colour space) for a view direction.

view_dir — unit vector pointing from camera into sky sun_dir — unit vector toward sun turbidity — atmosphere turbidity (1 = pure air, 10 = heavy haze)

Source

pub fn yxy_to_rgb(yxy: Vec3) -> Vec3

Convert CIE Yxy to linear sRGB.

Source §

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

Source §

impl<T> Borrow<T> for T
where T: ?Sized,

Source §

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

Source §

impl<T> Downcast for T
where T: Any,

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

Source §

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

Source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

Source §

impl<T> DowncastSync for T
where T: Any + Send + Sync,

Source §

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
