Struct SolidBoundary 

pub struct SolidBoundary { /* private fields */ }

A solid’s boundary, prepared once and asked about many points.

Classifying a point casts rays and counts crossings, which is cheap. What is not cheap is what the rays are cast against: every face’s trimming rings, polylined, plus its placement’s inverse. That work depends on the solid and the chord, never on the point, and asked point by point it was redone from scratch every time, which for a boolean means once per face piece. Measured on a four-hole cut, preparing took 3.5 ms against 5.6 µs of ray casting: six hundred times the work of the question being asked.

docs/PLAN.md §A named this as owed and said what it was worth.

Implementations

impl SolidBoundary

pub fn of( model: &Model, solid: &Shape, ring_chord: f64, tol: Tolerances, ) -> OgeomResult<Self>
