pub fn sample_edge_polylines(
solid: &BrepSolid,
chord_tolerance: f64,
) -> Result<Vec<(u64, Vec<Vec3>)>, String>Expand description
Display edge polylines for native in-process consumers (brep-render): every
NON-degenerate edge’s chord-tolerance samples as (edge_id, points), sorted
by edge id so the output is deterministic (the sample map is a HashMap).
The samples are the same shared samples the watertight tessellation uses, so
the displayed edges lie exactly on the mesh’s face boundaries.
