This is a simplified simulation of excitations of a quantum field(particles) interacting by exchanging pairs of virtual particles.

Green field contains 'real' particles, while the red one contains virtual particles, transferring interaction between the real ones.

Controls:
‍Left Mouse Click: Add a particle at the mouse position.
‍Spacebar: Toggle interaction between particles on/off.
‍W: Toggle visibility of the green field.
‍R: Toggle visibility of the red field.
‍Q: Remove all particles.
