Struct SearchlightRenderer 

pub struct SearchlightRenderer {
    pub c: f64,
    pub observer_pos: Vec3,
    pub max_boost: f32,
}

Renderer that modifies entity brightness based on velocity direction relative to observer.

Fields

c: f64

observer_pos: Vec3

max_boost: f32

Implementations

impl SearchlightRenderer

pub fn new(c: f64, observer_pos: Vec3) -> Self

pub fn entity_brightness( &self, entity_pos: Vec3, entity_velocity: Vec3, base_luminosity: f32, ) -> f32

Compute the apparent brightness of an entity given its position, velocity, and base luminosity.

pub fn batch_brightness(&self, entities: &[(Vec3, Vec3, f32)]) -> Vec<f32>

Compute brightness for multiple entities.

pub fn beamed_color( &self, entity_pos: Vec3, entity_velocity: Vec3, base_color: Vec4, ) -> Vec4

Apply beaming to a color by scaling its RGB components.

pub fn beaming_half_angle(&self, v: f64) -> f64

Compute the half-angle of the beaming cone (angle where intensity drops to half of forward max).
