Two body problem in 3D

Before an important step is taken in any domain of activity, heavy research is performed, and simulations run, so chances of failure are considerably reduced. As such, Two body problem in 3D wants to help you understand the mechanics of two objects interacting with only each other, known as the two body problem.

With the main window up, little time is spent accommodating, because of the clean, intuitive layout. Most of the space represents the preview area, with which you can interact in order to rotate the entire simulation.

Controls are all handled from a side panel, split into two tabs so you don’t feel overwhelmed by the abundance of information. The control view tab is where you get to manage general simulation view options, without having much impact on the simulation, except for the motion type drop-down menu.

Sure enough, you get to run the simulation several times to understand the theory behind the problem. Once acquainted, the initial values tab can be used to handle all simulation details, such as movement speed of objects, weight, simulation time, acceleration, and more. Luckily, there are playback controls in both tabs, so you don’t have to switch to preview changes.

Simulation types only count as three. The default one lets you study motion relative to the inertial frame, with a couple of other options for the second object relative to the first, as well as motion relative to the center mass.

Sadly, the application mostly serves for helping you visualize the process itself, with little to no technical info to extract. For instance, axis are not fitted with indicators, and even if you choose to display orbit data, the set of values is a bit difficult to comprehend, or put in practice.

Taking everything into consideration, we can say that Two body problem in 3D is sure to at least make you understand and visualize the theory behind the two body problem. Motion type can be selected, as well as behavior options for objects. Unfortunately, there are no export options, or possibility to bring up better detailed bits of info.
