Struct RasterizedModel 

pub struct RasterizedModel<S: Scalar> {
    pub vertices: HashMap<VertexId, Vector3<S>>,
    pub edges: HashMap<EdgeId, Vec<Vector3<S>>>,
    pub faces: HashMap<FaceId, Vec<TriangleFace<S>>>,
}

A Model rasterized once, with every sampled point/polyline/triangle kept alongside the id of the entity it came from.

This is the single place the crate turns topology into sampled geometry — PrimitiveScene rendering (rasterize_model) and ray picking (geop_cad_base::pick) both build on top of it, rather than each walking Model and sampling curves/surfaces on their own. That matters beyond not repeating code: it guarantees a pick can never disagree with what the viewer actually drew, because both read the same triangles.

Fields

vertices: HashMap<VertexId, Vector3<S>>

edges: HashMap<EdgeId, Vec<Vector3<S>>>

Each edge’s curve sampled into an n-point polyline.

faces: HashMap<FaceId, Vec<TriangleFace<S>>>

Each face’s trimmed region, triangulated (see face_triangles_uv) and mapped through surface.evaluate — one face generally maps to several triangles.
