Flat

facett_core::engine::source

Struct Flat

pub struct Flat;

Expand description

Flat — Z = 0. Use cases 1, 3 and 4. Zero cost: the engine special-cases a z_range() of (0, 0) and skips the elevation pass entirely.

Trait Implementations§

impl Clone for Flat

fn clone(&self) -> Flat

Returns a duplicate of the value. Read more

1.0.0 (const: unstable) · Source§

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

Performs copy-assignment from source. Read more

impl Copy for Flat

impl Debug for Flat

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

Formats the value using the given formatter. Read more

impl Default for Flat

fn default() -> Flat

Returns the “default value” for a type. Read more

impl ElevationSource for Flat

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

Batch form; default loops.

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

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.
