Functions:

plane2mesh(image, *[, level, max_edge_dist, ...])	Generate a triangular mesh from a 2D segmented image.
volume2mesh(image, *[, level])	Generate a tetrahedral mesh from a 3D segmented image.

nanomesh.image2mesh.plane2mesh(image: np.ndarray | Plane, *, level: float = None, max_edge_dist: int = 5, opts: str = 'q30a10', plot: bool = False) → MeshContainer

Generate a triangular mesh from a 2D segmented image.

Parameters

• image ((i,j) numpy.ndarray or Plane) – Input image to mesh.

• level (float, optional) – Level to generate contours at from image

• max_edge_dist (int, optional) – Maximum distance between neighbouring pixels in contours.

• opts (str, optional) – Options passed to triangulate(). For more info, see: https://rufat.be/triangle/API.html#triangle.triangulate

Returns

mesh – Triangulated 2D mesh with domain labels.

Return type

MeshContainer

nanomesh.image2mesh.volume2mesh(image: np.ndarray | Volume, *, level: float = None, **kwargs) → MeshContainer

Generate a tetrahedral mesh from a 3D segmented image.

Parameters

• image ((i,j,k) numpy.ndarray or Volume) – Input image to mesh.

• level (float, optional) – Contour value to search for isosurfaces (i.e. the threshold value). By default takes the average of the min and max value. Can be ignored if a binary image is passed as image.

• **kwargs – Optional keyword arguments passed to tetrahedralize()

Returns

volume_mesh – Instance of MeshContainer

Return type

MeshContainer
