Struct DirectionalLight 

pub struct DirectionalLight {
    pub direction: [f32; 3],
    pub color: [f32; 3],
    pub intensity: f32,
    pub casts_shadow: bool,
}

The sun — a single directional light for the whole scene. World space.

Fields

direction: [f32; 3]

Direction the light travels (from the sun toward the scene), world space. Need not be normalized — the backend normalizes. The N·L term uses the negation (the direction to the sun).

color: [f32; 3]

Linear RGB, 0..1 (may exceed 1 for extra punch; the output is clamped). [1.0; 3] is neutral white.

intensity: f32

Scalar brightness multiplier on color.

casts_shadow: bool

Whether this light casts stylized hard shadows (DL.3). The sun is the natural first shadow caster.

Trait Implementations

impl Clone for DirectionalLight

fn clone(&self) -> DirectionalLight

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DirectionalLight

impl Debug for DirectionalLight

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

Formats the value using the given formatter.

impl Default for DirectionalLight

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for DirectionalLight

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