Struct Light 

pub struct Light { /* private fields */ }

A light.

When a scene has no light and no Environment, init.js adds a default hemisphere light and a directional light.

use autumn_plugin_three::{Color, Light};

let sun = Light::directional().intensity(2.5).position([3.0, 5.0, 2.0]);
let sky = Light::hemisphere().ground(Color::hex(0x332211));

Implementations

impl Light

pub const fn new(kind: LightKind) -> Self

Makes a light of kind with the defaults for that kind.

pub const fn ambient() -> Self

An ambient light.

pub const fn directional() -> Self

A directional light.

pub const fn point() -> Self

A point light.

pub const fn spot() -> Self

A spot light.

pub const fn hemisphere() -> Self

A hemisphere light.

pub const fn color(self, color: Color) -> Self

Sets the color (the sky color for a hemisphere light).

pub const fn ground(self, color: Color) -> Self

Sets the ground color. Hemisphere lights only.

pub const fn intensity(self, value: f32) -> Self

Sets the intensity. Negative values become 0.

pub fn position(self, position: impl Into<Vec3>) -> Self

Sets the position. Ambient lights ignore it. For a hemisphere light, the position sets the sky direction. A non-finite component uses the default of the kind (LightKind::default_position).
