Enum PhotometricType 

pub enum PhotometricType {
    TypeA = 3,
    TypeB = 2,
    TypeC = 1,
}

Photometric measurement type.

Coordinate System Differences

• Type C: Vertical polar axis (0° = nadir, 180° = zenith). Standard for downlights, streetlights.
• Type B: Horizontal polar axis (0H 0V = beam center). Used for floodlights, sports lighting.
  • ⚠️ TODO: Implement 90° coordinate rotation for Type B → Type C conversion
  • Required transformation matrix: R_x(90°) to align horizontal axis to vertical
• Type A: Automotive coordinates. Rare in architectural lighting.
  • Currently parsed but may render incorrectly without coordinate mapping

Variants

TypeA = 3

Type A - Automotive photometry (rare)

TypeB = 2

Type B - Adjustable luminaires (floodlights, theatrical)

TypeC = 1

Type C - Architectural (most common)

Implementations

impl PhotometricType

pub fn from_int(value: i32) -> Result<Self>

Create from integer value.

Trait Implementations

impl Clone for PhotometricType

fn clone(&self) -> PhotometricType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PhotometricType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PhotometricType

fn default() -> PhotometricType

Returns the “default value” for a type.

impl PartialEq for PhotometricType

fn eq(&self, other: &PhotometricType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
