Struct PhotometricWeb 

pub struct PhotometricWeb { /* private fields */ }

A photometric web representing the full 3D luminous intensity distribution.

This structure provides efficient sampling of intensity values at any C-plane and gamma angle, handling symmetry automatically.

Implementations

impl PhotometricWeb

pub fn generate_ldc_mesh(&self, c_step: f64, g_step: f64, scale: f32) -> LdcMesh

Generate LDC solid mesh vertices.

Convenience method that creates an LdcMesh.

pub fn generate_colored_ldc_mesh( &self, c_step: f64, g_step: f64, scale: f32, color_mode: ColorMode, ) -> ColoredLdcMesh

Generate a colored LDC solid mesh.

Convenience method that creates a ColoredLdcMesh with positions, normals, colors, and indices.

pub fn generate_ldc_vertices( &self, c_step: f64, g_step: f64, scale: f32, ) -> Vec<(f32, f32, f32)>

Generate just the vertex positions for the LDC solid.

Returns a vector of (x, y, z) tuples.

impl PhotometricWeb

pub fn new( c_angles: Vec<f64>, g_angles: Vec<f64>, intensities: Vec<Vec<f64>>, symmetry: Symmetry, ) -> Self

Create a new PhotometricWeb from raw data.

pub fn sample(&self, c_angle: f64, g_angle: f64) -> f64

Sample intensity at any C and G angle using bilinear interpolation.

Handles symmetry automatically - you can query any angle in the full 0-360° C range and 0-180° G range regardless of stored symmetry.

Arguments

• c_angle - C-plane angle in degrees (will be normalized to 0-360)
• g_angle - Gamma angle in degrees (will be clamped to 0-180)

Returns

Intensity in cd/klm

pub fn sample_normalized(&self, c_angle: f64, g_angle: f64) -> f64

Sample normalized intensity (0.0 to 1.0) at any C and G angle.

This is useful for mesh generation where you want distances scaled relative to the maximum intensity.

pub fn max_intensity(&self) -> f64

Get the maximum intensity value.

pub fn min_intensity(&self) -> f64

Get the minimum intensity value.

pub fn symmetry(&self) -> Symmetry

Get the symmetry type.

pub fn c_angles(&self) -> &[f64]

Get the stored C-plane angles.

pub fn g_angles(&self) -> &[f64]

Get the stored gamma angles.
