Module noise_chunk 

NoiseChunk: cell-based terrain density evaluation with trilinear interpolation.

Matches vanilla’s NoiseChunk + NoiseBasedChunkGenerator.doFill() flow.

Vanilla wraps density functions with Interpolated markers. Only the inner functions (arguments to Interpolated) are evaluated at cell corners; the outer operations (squeeze, min, etc.) are applied per-block after trilinear interpolation. Each Interpolated marker gets its own independent channel.

Cell dimensions depend on the dimension’s noise settings.

Structs

NoiseChunk

Stores density values at cell corners for a single chunk and provides trilinear interpolation between corners for block-level resolution.

Constants

MAX_INTERP 🔒

Maximum number of interpolation channels supported. Overworld uses 8 (1 terrain + 4 noodle caves + 3 vein channels), nether/end use 1.

MAX_SLICE_LEN 🔒

Maximum slice length (z_corners * corners_y) across all dimensions. Overworld: (16/4+1) * (384/8+1) = 5 * 49 = 245. Rounded up for headroom.
