The most common ways to verify the evolution of an N- body system is checking the conservation of the energy and angular momentum.
Additionally, it is possible to check different phenomena that occur in the system like for example, the core-collapse.
Besides this, when performing large scale simulations or special initial conditions it is good to have a visualisation tool, that provide a general view of the evolution of the system.
We found really attractive to be able to see the evolution of a determined cluster through the time, which is the reason of the development of this graphical tool.
GravidyView is a lightweight and simple OpenGL N- body visualisation tool,
written in C/C++.
