Struct Detector 

Source 
pub struct Detector { /* private fields */ }
Expand description

Spherical detector that collects escaping photons and bins them by direction.

Uses CIE photometric coordinates:

  • C-angle: azimuth (0-360), C0 = +X, C90 = +Y
  • Gamma: from nadir (0-180), gamma=0 = -Z (down), gamma=180 = +Z (up)

Implementations§

Source§

impl Detector

Source

pub fn new(c_resolution_deg: f64, g_resolution_deg: f64) -> Self

Create a new detector with the given angular resolution.

Source

pub fn record(&mut self, direction: &Vector3<f64>, energy: f64)

Record an escaping photon by its world-space direction and energy.

Source

pub fn to_candela(&self, source_flux_lm: f64) -> Vec<Vec<f64>>

Convert accumulated bins to candela values.

cd = (energy_in_bin / solid_angle_of_bin) * (source_flux / total_energy)

Source

pub fn total_flux(&self, source_flux_lm: f64) -> f64

Total detected flux in lumens (for energy conservation validation).

Source

pub fn total_energy(&self) -> f64

Total accumulated energy.

Source

pub fn num_c(&self) -> usize

Number of C bins.

Source

pub fn num_g(&self) -> usize

Number of gamma bins.

Source

pub fn c_resolution_deg(&self) -> f64

C resolution in degrees.

Source

pub fn g_resolution_deg(&self) -> f64

Gamma resolution in degrees.

Source

pub fn bins(&self) -> &Vec<Vec<f64>>

Access raw bins (energy).

Source

pub fn counts(&self) -> &Vec<Vec<u64>>

Access raw counts.

Source

pub fn merge(&mut self, other: &Detector)

Merge another detector’s data into this one (for parallel accumulation).

Source

pub fn candela_at(&self, c_deg: f64, g_deg: f64, source_flux_lm: f64) -> f64

Sample the candela value at a specific (C, gamma) angle pair.

Uses bilinear interpolation from the fine-resolution bins. This allows extracting cd values at the source LDT’s exact (non-uniform) C-plane angles.

Source

pub fn resample(&self, c_step_deg: f64, g_step_deg: f64) -> Detector

Resample to a coarser resolution for export.
