Expand description

Global viewer settings resource.

This resource controls the viewer’s behavior and appearance. Changes to this resource trigger reactive updates to the scene.

Fields§

§scene_type: SceneType

Current scene type

§room_width: f32

Room/scene width in meters (X axis)

§room_length: f32

Room/scene length in meters (Z axis)

§room_height: f32

Room height in meters (Y axis, only for Room scene)

§mounting_height: f32

Luminaire mounting height in meters (for outdoor poles) For indoor scenes, this is ignored - use pendulum_length instead

§pendulum_length: f32

Pendulum/suspension length in meters (for indoor ceiling-mounted luminaires) 0.0 = flush mounted to ceiling

0.0 = hangs down from ceiling by this amount

§light_intensity: f32

Light intensity (not used directly, available for UI)

§show_luminaire: bool

Whether to show the luminaire model

§show_photometric_solid: bool

Whether to show the photometric solid

§show_shadows: bool

Whether to enable shadows

§ldt_data: Option<Eulumdat>

The LDT data to display

§luminaire_tilt: f32

Luminaire tilt angle in degrees (for road/outdoor scenes). 0 = pointing straight down, 90 = pointing horizontally across the road. Default is 15 degrees for road luminaires.

§lane_width: f32

Lane width in meters (for road scenes). Default 3.5m per EN 13201.

§num_lanes: u32

Number of lanes (for road scenes). Default 2 (one per direction).

§sidewalk_width: f32

Sidewalk width in meters. Default 2.0m.

§pole_spacing: f32

Pole spacing in meters. Calculated based on mounting height if 0. Typical: 3-4x mounting height for good uniformity.

Implementations§

Source §

impl ViewerSettings

Source

pub fn effective_pole_spacing(&self) -> f32

Calculate effective pole spacing. If pole_spacing is 0, use 3.5x mounting height (good uniformity).

Source

pub fn total_road_width(&self) -> f32

Calculate total road width including sidewalks.

Source §

impl ViewerSettings

Source

pub fn luminaire_height(&self, ldt: &Eulumdat) -> f32

Calculate the effective luminaire center height for the current scene.

For Room scenes:

Luminaire hangs from ceiling by pendulum_length
Center Y = room_height - pendulum_length - half_luminaire_height

For outdoor scenes (Road, Parking, Outdoor):

Luminaire is fixed to pole arm at mounting_height
Center Y = mounting_height - arm_offset - half_luminaire_height

Source

pub fn attachment_height(&self) -> f32

Get the attachment point height (where pendulum/cable starts). Only meaningful for Room scene.
