trimesh.path.exchange.misc¶
- trimesh.path.exchange.misc.dict_to_path(as_dict)¶
Turn a pure dict into a dict containing entity objects that can be sent directly to a Path constructor.
- Parameters:
as_dict (dict) – Has keys: ‘vertices’, ‘entities’
- Returns:
kwargs – Has keys: ‘vertices’, ‘entities’
- Return type:
dict
- trimesh.path.exchange.misc.edges_to_path(edges, vertices, **kwargs)¶
Given an edge list of indices and associated vertices representing lines, generate kwargs for a Path object.
- Parameters:
edges ((n, 2) int) – Vertex indices of line segments
vertices ((m, dimension) float) – Vertex positions where dimension is 2 or 3
- Returns:
kwargs – Kwargs for Path constructor
- Return type:
dict
- trimesh.path.exchange.misc.faces_to_path(mesh, face_ids=None, **kwargs)¶
Given a mesh and face indices find the outline edges and turn them into a Path3D.
- Parameters:
mesh (trimesh.Trimesh) – Triangulated surface in 3D
face_ids ((n,) int) – Indexes referencing mesh.faces
- Returns:
kwargs – Kwargs for Path3D constructor
- Return type:
dict
- trimesh.path.exchange.misc.lines_to_path(lines)¶
Turn line segments into a Path2D or Path3D object.
- Parameters:
lines ((n, 2, dimension) or (n, dimension) float) – Line segments or connected polyline curve in 2D or 3D
- Returns:
kwargs – kwargs for Path constructor
- Return type:
dict
- trimesh.path.exchange.misc.linestrings_to_path(multi)¶
Load shapely LineString objects into a trimesh.path.Path2D object
- Parameters:
multi (shapely.geometry.LineString or MultiLineString) – Input 2D geometry
- Returns:
kwargs – Keyword arguments for Path2D constructor
- Return type:
dict
- trimesh.path.exchange.misc.polygon_to_path(polygon)¶
Load shapely Polygon objects into a trimesh.path.Path2D object
- Parameters:
polygon (shapely.geometry.Polygon) – Input geometry
- Returns:
kwargs – Keyword arguments for Path2D constructor
- Return type:
dict
