Struct DopplerRenderer 

pub struct DopplerRenderer {
    pub c: f64,
    pub observer_pos: Vec3,
    pub intensity_shift: bool,
}

Renderer that shifts entity colors based on radial velocity toward observer.

Fields

c: f64

observer_pos: Vec3

intensity_shift: bool

Implementations

impl DopplerRenderer

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

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

Compute the Doppler-shifted color for an entity.

pub fn frequency_ratio(&self, entity_pos: Vec3, entity_velocity: Vec3) -> f64

Compute the Doppler frequency ratio (observed/emitted).

pub fn shift_colors(&self, entities: &[(Vec3, Vec3, Vec4)]) -> Vec<Vec4>

Batch process: shift colors for multiple entities.

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

Compute intensity scaling from Doppler effect. Intensity scales as (f_obs/f_source)^3 for a moving isotropic source.
