Expand description
Mesh-based geometric diff for STL/OBJ — pure Rust, no Open CASCADE.
Triangle meshes have no B-Rep faces or solids, so the STEP pipeline does not
apply. Instead each triangle is classified by distance to the other mesh:
a triangle of the new version with no nearby surface in the old one is
added, a triangle of the old version with nothing nearby in the new one is
removed, and the rest is unchanged. The result is emitted in the very same
[geom::MeshDiff] shape the 3D viewer already consumes (unchanged / added /
removed triangle layers), so STL/OBJ get the same green/red/grey view as STEP
— without needing the geometry helper.
Functions§
- diff
- Diff two meshes (raw file bytes) and return the colored layers.
