class datafusiontools.visualisation.voxeltiles.VoxelTiles(xyz: numpy.ndarray, dxdydz: numpy.ndarray, values: dict, result: int, cmap: Optional[Union[str, matplotlib.colors.Colormap]] = None)

Bases: object

3d B3dm tiling from numpy array

property enu_ecf_transform: numpy.ndarray

property voxel_models: numpy.ndarray

Numpy.array of object containing n*2 open3d.TriangleMesh voxel and values.

write_tiles(directory: str = '.')

Generate Cesium b3dm tiles (https://github.com/CesiumGS/3d-tiles/tree/main/specification) from voxels

directory: str

Output directory path

class datafusiontools.visualisation.cesium.CesiumViewer(result_folder: str, port: int = 8787)

Bases: object

Cesium online viewer for datafusion results

generate_voxel_tiles(xyz: numpy.ndarray, dxdydz: numpy.ndarray, values: dict, result: int, name: str, cmap: Optional[Union[str, matplotlib.colors.Colormap]] = None)

Create VoxelTiles object and attach it to the Cesium viewer.

xyz: array-like, shape (n, 3)

Voxel points positions.

dxdydz: array-like, shape (n, 3)

Voxels size

values: dict

dictionary holding voxel data / metadata

result: int

key of the column of the values you want to visualize

cmapstr or ~matplotlib.colors.Colormap, default: ‘gist_rainbow’

A .Colormap instance or registered colormap name. cmap is only used if c is an array of floats.

property voxel_tiles

class datafusiontools.visualisation.serve.CesiumServer(tiles_directory: Optional[str] = None, port: int = 8787)

Bases: object

Serve cesium viewer locally :param port: pick the port to serve the cesium viewer (default port 8787)

start_server()

stop_server()

property tiles_path

property tiles_served

property tiles_url

class datafusiontools.visualisation.serve.ServerThread(app, port)

Bases: threading.Thread

Create a thread to run server in backgound :param port: a flask app :param app: pick the port to serve the cesium viewer (default port 8787)

run()

Method representing the thread’s activity.

You may override this method in a subclass. The standard run() method invokes the callable object passed to the object’s constructor as the target argument, if any, with sequential and keyword arguments taken from the args and kwargs arguments, respectively.

shutdown()
