Particle flow reconstruction: visualize simulated collision events

[jpata]

This video visualizes one simulated collision event: https://www.youtube.com/shorts/vM4Qbbkym98
This visualization shows hits in the detector and straight tracks in a simplified way.

It was prepared using this older notebook: https://github.com/jpata/particleflow/blob/279f6ae1f2c869bc913f741443c8f84fc83f136e/notebooks/clic/clic-visualize.ipynb

In reality, the tracks are actually curved due to magnetic field, and are more correctly visualized in this notebook: https://github.com/jpata/particleflow/blob/243fc61c9566d09cbb8891d288e59ae9dbf31762/notebooks/clic/clic-visualize.ipynb

It would be great to have a visualization app that can visualize different events in more detail and more accurately, including producing videos.

The task has the following steps:

• Unified notebook or visualization app: prepare a new, well-documented notebook or visualization app that combines the curved tracks and rotating render from the two above notebooks.
• Unified cluster and hit visualization: Experiment with putting hits and clusters on the same panel instead of separate panels. The cluster size should be proportional to the cluster energy, and it should not occlude hits
• Prepare a video showing the tracks + hits&clusters and target particles side-by-side
• Jets and missing transverse energy: add the visualization of jets in 2D or 3D in the notebook

The datasets can be downloaded from here: https://zenodo.org/records/8260741. Specifically, the following datasets have interesting physics events that could be visualized:
