Struct Beardifier 

pub struct Beardifier {
    rigids: Vec<Rigid>,
    junctions: Vec<JigsawJunction>,
    affected_box: Option<BoundingBox>,
}

Computes terrain density contributions from nearby structure pieces and junctions.

Built per-chunk from the chunk’s own starts plus referenced neighbor starts (mirrors vanilla’s StructureManager.startsForStructure). Queried per-block by NoiseChunk::fill after the outer density-function ops, matching vanilla’s cacheAllInCell(add(final_density, beardifier)) integration.

Fields

rigids: Vec<Rigid>

junctions: Vec<JigsawJunction>

affected_box: Option<BoundingBox>

Union of all piece/junction bounding boxes inflated by 24. Points outside this box get 0.0 without iterating pieces.

Implementations

impl Beardifier

pub fn for_structures_in_chunk<'a, I>( starts: I, chunk_x: i32, chunk_z: i32, ) -> Self

where I: IntoIterator<Item = &'a StructureStart>,

Collect rigid pieces and junctions from structure starts that affect this chunk.

starts should yield every StructureStart whose pieces could affect this chunk — typically the chunk’s own starts plus all referenced neighbor starts (vanilla collects these via StructureManager.startsForStructure).

chunk_x and chunk_z are chunk coordinates (not block coordinates).

Mirrors vanilla’s forStructuresInChunk:

• Non-jigsaw pieces (projection: None) → added as rigid with ground_level_delta = 0.
• Jigsaw RIGID pieces → added as rigid with stored ground_level_delta, junctions collected.
• Jigsaw TERRAIN_MATCHING pieces → not added as rigid; junctions still collected.

pub const fn is_empty(&self) -> bool

Returns true if there are no pieces or junctions affecting terrain.

pub fn compute(&self, block_x: i32, block_y: i32, block_z: i32) -> f64

Compute the total density contribution at a world-space block position.

Returns 0.0 if no structures are nearby.
