Functions

column_base_height 🔒

getBaseHeight(WORLD_SURFACE_WG)-compatible height scan. Uses preliminary_surface_level + 16 as an upper bound to avoid scanning empty upper atmosphere, and the cell-based iterator so 8-corner density evaluations are shared across Y values in each cell.

column_interpolated_density 🔒

Single-point getInterpolatedDensity. Exposed for GenerationContext.

find_solid_block_below_air 🔒

Finds the highest solid block below air in a single base-noise column.

interpolated_density 🔒

Evaluate terrain density at a single block position using cell-based interpolation matching vanilla’s NoiseChunk: inner functions at 8 cell corners, trilinear interpolation per channel, then outer operations.

iterate_noise_column_capped 🔒

Same as iterate_noise_column_with_aquifer but only scans Y values up to max_y_inclusive. Used by base_height with an estimate from preliminary_surface_level + 16 to skip empty upper atmosphere — reducing cell-corner density evaluations from O(height) to O(estimate_depth).

iterate_noise_column_with_aquifer 🔒

Matches vanilla’s iterateNoiseColumn: iterates by Y cells, evaluating inner density functions at 8 cell corners, trilinearly interpolating each channel independently, then applying outer operations (squeeze, min, etc.) per-block via combine_interpolated.
