Struct ThreeMfReadResult 

pub struct ThreeMfReadResult {
    pub model_part: String,
    pub unit: ThreeMfUnit,
    pub meshes: Vec<ThreeMfMesh>,
    pub instances: Vec<ThreeMfInstance>,
    pub positions: Vec<f64>,
    pub indices: Vec<u32>,
    pub triangle_colors: Vec<Option<[u8; 3]>>,
}

Everything read_3mf recovered from a package.

Fields

model_part: String

The part the model was read from (from the start-part relationship).

unit: ThreeMfUnit

The unit the file declared, before conversion.

meshes: Vec<ThreeMfMesh>

One entry per mesh-bearing <object> in <resources>, in document order — including any the build never places.

instances: Vec<ThreeMfInstance>

The <build>, flattened through <components>: one entry per placed mesh. Objects of a type other than model are not placed.

positions: Vec<f64>

Every instance’s triangles in world coordinates, millimetres — the soup the mesh-to-solid chain reads.

indices: Vec<u32>

Triangle corners into positions/3, winding preserved (reversed for a mirrored instance so the result stays outward-facing).

triangle_colors: Vec<Option<[u8; 3]>>

Parallel to the flattened triangles (indices.len() / 3 entries, each following its triangle through the instance order and a mirrored placement’s winding reversal) when any placed triangle resolves to a colour; EMPTY otherwise.

Implementations

impl ThreeMfReadResult

pub fn vertex_count(&self) -> usize

pub fn triangle_count(&self) -> usize

pub fn instance_mesh(&self, instance: usize) -> Option<(Vec<f64>, Vec<u32>)>

ONE instance’s triangle soup: its world-space vertices and its triangles rebased onto them. A multi-instance build is several bodies in one buffer — this is how a consumer takes them apart by PLACEMENT without knowing how read_3mf laid them out. The importer does not need it: the mesh-to-solid chain splits the whole soup into its vertex-connected components and reconstructs each as its own body. It is the answer when the question is which instance a body came from, which the geometry alone cannot say (two instances that touch are one component).
