Struct Sampled 

pub struct Sampled { /* private fields */ }

Sampled — height from a pure (x, y) -> z function plus a declared range. facett-geomap wraps its terrain heightfield in this; facett-core never learns what a DEM is.

Implementations

impl Sampled

pub fn new( kind: &'static str, range: (f64, f64), sample: impl Fn(f64, f64) -> f64 + Send + Sync + 'static, ) -> Self

Trait Implementations

impl Debug for Sampled

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

Formats the value using the given formatter.

impl ElevationSource for Sampled

fn elevation(&self, _id: u32, p: WorldPos) -> f64

Height of feature id, given the world position the PositionSource produced (a terrain source samples at p; a metric source ignores p).

fn z_range(&self) -> (f64, f64)

The [min, max] this source can ever emit — the culler needs it to grow 2D bounds into 3D ones without sampling every feature.

fn kind(&self) -> &'static str

fn elevations(&self, ids: &[u32], pos: &[WorldPos], out: &mut Vec<f64>)

Batch form; default loops.
