Expand description

Column-level cache for xz-only density function results.

Supports two modes:

  • Grid mode (init_grid() called): Pre-computes a 2D grid of all in-chunk quart positions. ensure() does O(1) grid lookups for exact grid points and evaluates other positions on the fly.
  • No-grid mode (default): Single-entry lazy cache that recomputes when the exact coordinates change.

Fields§

§x: i32

Raw x block coordinate (for non-flat router functions).

§z: i32

Raw z block coordinate (for non-flat router functions).

§qx: i32

X coordinate used to evaluate the cached values.

§qz: i32

Z coordinate used to evaluate the cached values.

Implementations§

Source§

impl OverworldColumnCache

Source

const GRID_SIDE: i32 = 5

Grid side length (quart positions per axis).

Source

pub fn new() -> Self

Create a new column cache without a pre-computed grid.

Source

pub fn init_grid( &mut self, chunk_block_x: i32, chunk_block_z: i32, noises: &OverworldNoises, )

Pre-compute flat-cached values for all quart positions in a chunk.

After this call, ensure() for matching grid points copies from the grid (O(1)). Other positions are evaluated at their exact coordinates.

Source

pub fn ensure(&mut self, x: i32, z: i32, noises: &OverworldNoises)

Ensure the cache is populated for the given (x, z) block coordinates.

Grid-aligned in-bounds positions load from the pre-computed grid. Every other position is evaluated at its exact coordinates.
