Gravity Balls is a physics-based 3D simulation project built using OpenGL and GLUT, where multiple balls move under the influence of gravity, friction, and collision dynamics. This project is a fun and interactive way to visualize basic physics in action using graphical rendering.
- ✅ Realistic gravity-based motion simulation
- ✅ Collision detection and response between balls
- ✅ Boundary collisions with wall rebound effects
- ✅ Frictional slowdown to simulate energy loss
- ✅ Rendered using
glutSolidSpherein a 3D space
- Language: C++
- Graphics: OpenGL, GLUT
- Platform: Windows Visual Studio 2022 (VS Solution File included)
- Download all the files on your computer.
- Open
GravityBalls.slnin Visual Studio. - Make sure your system has OpenGL and GLUT libraries set up (Visual Studio should handle this if you're using the included files).
- Press
Ctrl + F5to build and run.
The simulation starts automatically, but you can interact and modify parameters in real time using the following keyboard shortcuts:
| Key | Action |
|---|---|
2 / 8 |
Decrease / Increase Gravity |
4 / 6 |
Decrease / Increase Friction |
A / D |
Decrease / Increase Elasticity |
Q / E |
Decrease / Increase Entropy |
< / > |
Decrease / Increase Time Scale |

| (Shown on top of simulation window) | Real-time updated values: Gravity, Friction, Elasticity, Ball Count, Entropy, Time Scale, etc. |
You can also customize the number of balls and initial settings directly in main.cpp before compiling.
🧪 Feel free to experiment with combinations to see how the environment reacts!
This project is for educational purposes and open to contributions.
Feel free to fork and modify it!
