3-D Scientific Visualization in the Jupyter Notebook

ipygany

Jupyter Interactive Widgets library for 3-D mesh analysis

ipygany is an early developer preview. Features and implementation are subject to change.

Features

ipygany has many features including:

• VTK loader for displaying your computation results in the Jupyter Notebook
• Structured and Unstructured grids support
• 2-D cell based meshes support (quads, triangles...) as well as 3-D cell based meshes support (tetrahedrons, quadratic tetrahedrons...)
• Animations
• IsoColor effect
• Warp effect
• IsoSurface computation
• Threshold effect (for visualizing only the parts that are inside of a range of data)
• Point cloud visualization
• Water effect, for nice water visualization with real-time caustics

Most of those features are very fast, because they are computed entirely on the GPU.

Examples

Animations: Dynamically update the mesh from Python (data generated with https://fastscapelib.readthedocs.io)

IsoColor: Use color mapping to highlight your data

Threshold: Hide parts of your mesh

Water effect: Visualize your water flow data with a realistic water effect

Installation

You can install ipygany with conda:

conda install -c conda-forge ipygany

Or using pip:

pip install ipygany
jupyter nbextension enable --py --sys-prefix ipygany

If you want to load vtk files in ipygany, you also need to install vtk, you can install it with conda:

conda install -c conda-forge vtk

For JupyterLab

You need to install the labextension for ipygany:

jupyter labextension install @jupyter-widgets/jupyterlab-manager ipygany
