pysdic.PointCloud.from_meshio

classmethod PointCloud.from_meshio(mesh, load_properties=True)

Create a PointCloud object from a meshio.Mesh object.

The points are extracted from the mesh vertices and the properties are read from the point data.

See also

• to_array() method for converting the point cloud back to a NumPy array.

Note

Only the vertices of the mesh are used to create the point cloud. Cells are ignored.

Parameters:

• mesh (meshio.Mesh) – A meshio Mesh object containing the vertices.

• load_properties (bool, optional) – If True, the point data properties from the mesh will be loaded into the point cloud. Default is True.

Returns:

A PointCloud object containing the points extracted from the mesh vertices.

Return type:

PointCloud

Raises:

ValueError – If the mesh does not contain any points.

Examples

Creating a PointCloud object from a meshio.Mesh object.

import meshio
from pysdic import PointCloud

# Load a mesh using meshio
mesh = meshio.read('path/to/mesh_file.vtk')

# Create a point cloud from the mesh
point_cloud = PointCloud.from_meshio(mesh)

Now, point_cloud is a PointCloud object containing the points extracted from the mesh vertices.
