Struct three::DirectionalLight

pub struct DirectionalLight { /* fields omitted */ }

The light source that illuminates all objects equally from a given direction, like an area light of infinite size and infinite distance from the scene; there is shading, but cannot be any distance falloff.

Methods

impl DirectionalLight

fn has_shadow(&self) -> bool

Returns true if it has ShadowMap, false otherwise.

fn set_shadow(&mut self, map: ShadowMap, extent_y: f32, near: f32, far: f32)

Adds shadow map for this light source.

Methods from Deref<Target = Object>

fn set_visible(&mut self, visible: bool)

Invisible objects are not rendered by cameras.

fn look_at<P>(&mut self, eye: P, target: P, up: Option<Vector3<f32>>) where
    P: Into<[f32; 3]>, 

Rotates object in the specific direction of target.

fn set_transform<P, Q>(&mut self, pos: P, rot: Q, scale: f32) where
    P: Into<Point3<f32>>,
    Q: Into<Quaternion<f32>>, 

Set both position, orientation and scale.

fn set_position<P>(&mut self, pos: P) where
    P: Into<Point3<f32>>, 

Set position.

fn set_orientation<Q>(&mut self, rot: Q) where
    Q: Into<Quaternion<f32>>, 

Set orientation.

fn set_scale(&mut self, scale: f32)

Set scale.

fn sync(&mut self, scene: &Scene) -> NodeInfo

Get actual information about itself from the scene.

Panics

Panics if scene doesn't have this Object.
