ndv

Simple, fast-loading, asynchronous, n-dimensional viewer for Qt, with minimal dependencies.

from qtpy import QtWidgets
from ndv import NDViewer
from skimage import data  # just for example data here

qapp = QtWidgets.QApplication([])
v = NDViewer(data.cells3d())
v.show()
qapp.exec()

NDViewer

• supports arbitrary number of dimensions, with 2D/3D view canvas, and sliders for all non-visible dims
• sliders support integer as well as slice (range)-based slicing
• colormaps provided by cmap
• supports vispy and pygfx backends
• supports any numpy-like duck arrays, with special support for features in:
  • xarray.DataArray
  • dask.array.Array
  • tensorstore.TensorStore
  • zarr
  • dask

Installation

The only required dependencies are numpy and superqt[cmap,iconify]. You will also need a Qt backend (PyQt or PySide) and one of either vispy or pygfx:

pip install ndv[pyqt,vispy]
