Struct SymmetryHandler 

pub struct SymmetryHandler;

Handler for symmetry-based operations on photometric data.

Implementations

impl SymmetryHandler

pub fn expand_to_full(eulumdat: &Eulumdat) -> Vec<Vec<f64>>

Expand symmetric data to full 360° distribution.

Takes the stored (reduced) intensity data and expands it based on the symmetry type. Returns a full intensity matrix with all C-planes from 0° to 360°.

pub fn expand_c_angles(eulumdat: &Eulumdat) -> Vec<f64>

Get the C-plane angles for the full 360° distribution.

pub fn get_intensity_at(eulumdat: &Eulumdat, c_angle: f64, g_angle: f64) -> f64

Get intensity at any C and G angle by interpolation.

This handles symmetry automatically, interpolating between stored data points.

pub fn polar_to_cartesian( c_angle: f64, g_angle: f64, intensity: f64, ) -> (f64, f64)

Convert polar coordinates (C, G, intensity) to Cartesian for visualization.

Returns (x, y) coordinates where:

• x axis points right (C=90°, G=90°)
• y axis points up (C=0°, G=90°)
• The returned coordinates are scaled by intensity.

pub fn generate_polar_points( eulumdat: &Eulumdat, c_index: usize, ) -> Vec<(f64, f64)>

Generate points for a polar diagram of a C-plane.

Returns a vector of (x, y) points for rendering.
