Struct LightSpec 

pub struct LightSpec {
    pub azimuth_deg: f32,
    pub elevation_deg: f32,
    pub intensity: f32,
}

-light AZIMUTH,ELEVATION,INTENSITY — directional light override for the 3D→raster renderer.

azimuth and elevation are in degrees; intensity is a unit scalar in [0.0, ~] multiplied into the diffuse term. The renderer always also applies a small constant ambient term so back-faces stay visible.

Fields

azimuth_deg: f32

elevation_deg: f32

intensity: f32

Implementations

impl LightSpec

pub fn default_light() -> Self

Default directional light: from the upper-right-front quadrant at unit intensity. Matches the renderer baseline so explicit -light is never required.

pub fn parse(s: &str) -> Result<LightSpec, String>

Parse AZIMUTH,ELEVATION,INTENSITY. All three components are required; intensity is clamped to >= 0.0.
