This is a simple simulator for a system of bodies with circular shape. It is written in Java and uses the Swing library for the GUI.

• Collision detection and elastic collision response

  

• Forces

  

• Gravity

  

• Medium resistance

  

To build the project clone the repository and run the following command in the root directory:

$ ./gradlew build

To run the simulator execute the following command in the root directory:

$ ./gradlew run

• Use numbers 1-6 to select to switch extensions on and off.
• Use s to set a few bodies.
• Use r or R to set few bodies.
• Use a to add a random velocity to all bodies.
• Use m to toggle collision mesh visualization.
• Use t to toggle trails.
• Use c to clear trails and collision mesh.
