Animating collider processes with event-time-frame format

High Energy Physics processes, such as hard scattering, parton shower, and hadronization, occur at colliders around the world, e.g., Large Hadron Collider in Europe. The various steps are also components within corresponding Monte-Carlo simulations. They usually considered to an instant displayed MC simulations intricate paths hard-coded with HepMC format. We recently developed a framework convert HEP event records into online 3D animations, aiming for visual studies science popularization, where most difficult parts about designing timeline particles' movement. As by-product, we propose here event-time-frame format animation data exchanging persistence, which is potentially helpful other visualization works. code maintained https://github.com/lyazj/hepani, web service available https://ppnp.pku.edu.cn/hepani/index.html.
