Gravity3D

Gravity3D is a lightweight educational software application whose purpose is to help you simulate the gravitational interaction between galaxies as they collide via OpenGL. The tool can be deployed on all Windows flavors out there.

The utility is portable so you can drop it on pen drives or other removable devices to carry it with you all the time. Plus, you may open it without having to apply administrative privileges. You can run it directly from the storage device.

Since it does not make changes to your Windows registry and generate additional setup items, you can get rid of it with the aid of a simple deletion task. Opening its GUI can be done by double-clicking on the executable file because you do not have to go through an installation process.

Gravity3D sports a clean configuration panel that gathers a few setup parameters which need to be tweaked before triggering a simulation process. A ‘Readme’ file is included in the package and comprises useful details about the setup options.

You are offered the possibility to set the number of stars, specify the number of galaxies, adjust the background color, enable fog and color cycling modes, as well as adjust motion blur, color mapping, size of the point, brightness of the stars, and performance.

Several preset hotkeys parameters are available while running the application in the simulation mode. The action triggered by each key is explained in the main window. Tests have pointed out that Gravity3D carries out tasks quickly and without errors. It is quite friendly with system resources so the overall performance of the computer is not hampered.

To sum things up, Gravity3D comes bundled with several handy features for helping you carry out simulations between colliding galaxies. It can be configured by rookies and professionals alike.
