Generate your own realistic pedestrian shapes and simulate contacts

We have just released an open-source software, available via an online platform powered by Streamlit and via Python and C++ scripts, to

• generate anthropometry-based anisotropic pedestrian shapes in 2D and in 3D

  
  

• handle mechanical contacts between the agents in a crowd simulation, by solving the mechanical equations of motion with a discrete-element method.

Importantly, this software does not prescribe the desired velocities and "social interactions". Therefore, it should not be regarded as a crowd simulator, but as a cutting-edge tool to assist the development of crowd simulators that are based on realistic shapes and physically supported contact forces between agents.
