Struct DirectionalLight 

pub struct DirectionalLight {
    pub direction: [f32; 2],
    pub color: [f32; 3],
    pub intensity: f32,
    pub cast_shadows: bool,
}

Directional (sun) light parameters.

A single infinitely-distant directional light source, equivalent to Mapbox’s "directional" light type.

Fields

direction: [f32; 2]

Light direction toward the light source, in world space.

Encoded as [azimuth_deg, altitude_deg]:

• azimuth_deg: compass bearing of the sun (0 = north, 90 = east). Default: 210.0 (south-west, matching Mapbox’s default).
• altitude_deg: elevation angle above the horizon. Default: 45.0.

color: [f32; 3]

Directional light colour (linear RGB, 0–1). Default: white.

intensity: f32

Directional intensity multiplier. Default: 0.5.

cast_shadows: bool

Whether this light should cast shadows (reserved for Phase 7 cascaded shadow maps). Default: false.

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 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.
