Struct SignedDistanceGrid 

pub struct SignedDistanceGrid { /* private fields */ }

Precomputed signed samples plus exact cached boundary guards for thin features. All data is immutable and can be shared through SceneContext::cache.

Implementations

impl SignedDistanceGrid

pub fn cached<Key: Eq + Hash + Send + Sync + 'static>( context: &SceneContext<'_>, key: Key, surface: Arc<VectorSurface>, bounds: Rect, dimensions: [u32; 2], limits: SimulationLimits, ) -> Result<Arc<Self>, ValidationError>

Shares prepared immutable grids in the existing bounded SceneCache. The key includes geometry identity, resolution and preparation budgets.

pub fn new( surface: Arc<VectorSurface>, bounds: Rect, dimensions: [u32; 2], limits: SimulationLimits, ) -> Result<Self, ValidationError>

Prepares an explicitly resolved grid under SimulationLimits; no downsampling fallback.

pub fn bytes(&self) -> u64

Exact retained grid and boundary payload, suitable for SceneCache cost accounting.

pub fn sample(&self, point: Point) -> (f64, [f64; 2])

Bilinear grid sampling, with an exact immutable boundary guard within one cell diagonal.
