Struct PointLight 

pub struct PointLight {
    pub transform: NodeTransform,
    pub color: Vec4,
    pub bias: f32,
    /* private fields */
}

point lights nodes represent point lights in the Scene

point lights are lights that are cast from a single point. light is calculated by getting the distance and direction to the point light position.

Fields

transform: NodeTransform

transform component for point light

color: Vec4

the light color default is White

bias: f32

Implementations

impl PointLight

pub fn new() -> PointLight

create a point light.

pub fn get_buffered_data(&self, index: usize) -> PointLightBufferData

returns the formatted buffer data

pub fn get_intensity(&self) -> f32

get the nodes intensity

pub fn get_intensity_mut(&mut self) -> &mut f32

get the nodes intensity

pub fn set_intensity(&mut self, intensity: f32)

how strong the light is.

this will also update the far plane for shadows since more intense lights go further

pub fn calculate_far_plane(intensity: f32, threshold: f32) -> f32

calculate the far_plane for a given intensity so that the shadow cutoff is at a light level thrshhold

to save resources we only want to render shadows as far as the light is visible so we can cut it off at a given threshold

pub fn get_shadow_transformations(&self) -> [Mat4; 6]

pub fn set_color(&mut self, color: impl Into<Vec4>) -> &mut PointLight

set the light color

pub fn get_color_mut(&mut self) -> &mut Vec4

get the light color

Trait Implementations

impl Buildable for PointLight

type Builder = PointLightBuilder

Node Specific Builder

fn builder() -> <PointLight as Buildable>::Builder

impl Default for PointLight

fn default() -> PointLight

Returns the “default value” for a type.

impl Node for PointLight

fn get_transform(&mut self) -> &mut NodeTransform

gets the transform of the node.
