Assembler::distance(p) and stream_distance fold the brush stream into a scalar field (Add=min, Subtract=max(d,-b), Intersect=max). Exact for boxes, oriented boxes and Z cylinders; surface-exact non-overestimating bounds for domes and floret arms. Honours every op on every primitive, unlike the polygon kernel's non-box cutter warnings. Seam for isosurface meshing. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

//! Constructive-solid-geometry tools for CultGeometry.

//!
|
|
//! This crate borrows RealtimeCSG's useful public shape: ordered brushes,
|
|
//! operation types, dirtied generations, prefix checkpoints, and rebuildable
|
|
//! output meshes. The hidden native RealtimeCSG kernel is not public, so this
|
|
//! starts with the smallest honest CSG organ: exact box subtraction against
|
|
//! additive boxes, plus additive procedural primitives for the habitat forms we
|
|
//! keep needing.
