Struct VertInterner 

pub struct VertInterner {
    pub verts: Vec<R3>,
    pub verts_f64: Vec<Vec3>,
    /* private fields */
}

Exact-point interner: one id per distinct point, with two disjoint key spaces. f64-representable points (all input vertices, and any constructed point that rounds exactly) key on their coordinate bits — no rational hashing, so untouched input triangles intern for the cost of a HashMap probe. Only genuinely non-representable constructed points use the rational map. verts_f64 caches the correctly rounded approximation of every id (exact for bit-keyed points), which downstream float filters and output assembly reuse instead of re-rounding.

Fields

verts: Vec<R3>

verts_f64: Vec<Vec3>

Implementations

impl VertInterner

pub fn intern_f64(&mut self, v: Vec3) -> u32

Intern an exact-f64 point (input mesh vertices): zero rational work on hits; one R3::from_vec3 on first sight, for the exact table.

pub fn intern(&mut self, p: &R3) -> u32

Intern an exact rational point. Representable points route to the f64 key space so both paths agree on ids.

Trait Implementations

impl Default for VertInterner

fn default() -> VertInterner

Returns the “default value” for a type.
