}

All FW tuning in one place. Geometry fields are in cells (mip-0 voxels) and radians; rates are intensity units (0..=63) per second. The styling knobs at the bottom are read by the renderers from FW.2 on — unread in FW.0.

Fields

cone_half_angle: f32

Half-angle of the facing cone, radians.

cone_taper: f32

Angular taper band inside the half-angle over which intensity falls to zero (smooth cone rim), radians.

range: f32

Facing-cone reach, cells.

peripheral_range: f32

360° close-range vision, cells (an observer is never blind in their own back at arm’s length).

edge_taper: f32

Radial taper band inside range / peripheral_range / heard-blob radii, cells.

decks: Vec<DeckBand>

The decks, index-aligned with FowObserver::deck and every per-deck query. Must stay the same length across FogOfWar::set_config calls (layers are keyed by index).

light_gate: Option<LightGate>

Decision 5 — None = geometric visibility only.

fade_in: f32

Intensity rise rate toward a live (Visible/Heard) target.

fade_out: f32

Intensity fall rate when leaving sight, down to memory_intensity.

memory_intensity: u8

Where a freshly-demoted Memory cell settles before slow decay.

memory_decay: f32

Decision 7 — slow decay rate from memory_intensity toward memory_floor. 0 = memories never fade.

memory_floor: u8

Decayed-memory minimum intensity — old memories stay barely readable rather than vanishing back to Unseen.

heard_radius: f32

Heard-blob radius in cells per unit of loudness.

heard_duration: f32

Seconds a heard blob stays live before fading out.

memory_dim: f32

FW.2+ styling: Memory/Heard brightness multiplier.

memory_desaturate: f32

FW.2+ styling: Memory/Heard desaturation amount 0..=1.

Implementations

impl VisionConfig

pub fn for_decks(decks: Vec<DeckBand>) -> Self

Defaults tuned for ship scale (~1 voxel ≈ 10 cm): a 120° cone reaching 96 cells, 12-cell peripheral, light gate off.

pub fn deck_for_z(&self, z: i32) -> Option<usize>

Index of the deck whose [z_top, z_bottom] contains grid-local z (the head-follow deck pick, CA round-3 convention: feed the HEAD z, not the feet).

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for VisionConfig

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

Formats the value using the given formatter.

impl PartialEq for VisionConfig

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

Equality operator ==.
