trimesh.repair¶
repair.py¶
Fill holes and fix winding and normals of meshes.
- trimesh.repair.broken_faces(mesh, color=None)¶
Return the index of faces in the mesh which break the watertight status of the mesh.
- Parameters
mesh (trimesh.Trimesh) – Mesh to check broken faces on
color ((4,) uint8 or None) – Will set broken faces to this color if not None
- Returns
broken – Indexes of mesh.faces
- Return type
(n, ) int
- trimesh.repair.fill_holes(mesh)¶
Fill single- triangle holes on triangular meshes by adding new triangles to fill the holes. New triangles will have proper winding and normals, and if face colors exist the color of the last face will be assigned to the new triangles.
- Parameters
mesh (trimesh.Trimesh) – Mesh will be repaired in- place
- trimesh.repair.fix_inversion(mesh, multibody=False)¶
Check to see if a mesh has normals pointing “out.”
- Parameters
mesh (trimesh.Trimesh) – Mesh to fix.
multibody (bool) – If True will try to fix normals on every body
Notes
mesh.face : may reverse faces
- trimesh.repair.fix_normals(mesh, multibody=False)¶
Fix the winding and direction of a mesh face and face normals in-place.
Really only meaningful on watertight meshes but will orient all faces and winding in a uniform way for non-watertight face patches as well.
- Parameters
mesh (trimesh.Trimesh) – Mesh to fix normals on
multibody (bool) – if True try to correct normals direction on every body rather than just one
Notes
mesh.faces : will flip columns on inverted faces
- trimesh.repair.fix_winding(mesh)¶
Traverse and change mesh faces in-place to make sure winding is correct, with edges on adjacent faces in opposite directions.
- Parameters
mesh (Trimesh object) –
Notes
mesh.face : will reverse columns of certain faces
