Physics Simulations

This application is modified from the Globus Compute Golf Demo.

Simulates the physics of golf balls landing on a randomly generated golf green using perlin noise for terrain generation and pybullet3 for physics simulations. This application is embarrassingly parallel---every ball is simulated in its own task.

Installation

This application requires numpy, matplotlib, scipy, and pybullet3 which can be installed automatically when installing the TaPS package.

pip install -e .[physics]

Example

The following command simulated 32 balls where each ball is simulated in a separate task.

python -m taps.run --app physics --app.simulations 32 --engine.executor process-pool

The initial and final ball positions are plotted and saved to {run_dir}/images/. By default, the simulations run at "real time". I.e., sleeps are added at each timestep to ensure timesteps take as long as they would in real life. This can be disabled with --app.real-time false.
