Struct EmissiveGlyph 

pub struct EmissiveGlyph {
    pub position: Vec3,
    pub color: Color,
    pub emission_strength: f32,
    pub radius: f32,
    pub glyph_character: char,
    pub enabled: bool,
    pub emission_threshold: f32,
}

Auto light source generated from a bright glyph that exceeds the emission threshold.

Fields

position: Vec3

color: Color

emission_strength: f32

radius: f32

glyph_character: char

enabled: bool

emission_threshold: f32

The threshold above which a glyph emission value becomes a light source.

Implementations

impl EmissiveGlyph

pub fn new(position: Vec3, character: char, color: Color, emission: f32) -> Self

pub fn is_active(&self) -> bool

Check if the given emission value exceeds the threshold.

pub fn effective_intensity(&self) -> f32

The effective intensity above the threshold.

pub fn irradiance_at(&self, point: Vec3) -> Color

Compute irradiance at a world point (treated as a small point light).

pub fn auto_radius(emission_strength: f32) -> f32

Estimate emissive glyph radius based on emission strength.

pub fn from_glyph_data( character: char, emission: f32, position: Vec3, color: Color, threshold: f32, ) -> Option<Self>

Create from raw glyph data (character, emission value, position).

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

Performs copy-assignment from source.

impl Debug for EmissiveGlyph
