Gravitas is a fully scriptable, real-time 3D gravity simulator. Scripts written in the integrated development environment (IDE) are interpreted by the simulator and allow users to create any imaginable planetary setup.

Once inside the simulated system, the user can move around in 3D space to observe the gravitational interactions of the celestial bodies. With the aid of the head-up display (HUD), users can track bodies and view live information about the simulation as it progresses.

Gravitas makes use of the powerful yet simple-to-use Lua scripting language, which offers the perfect introduction to programming for beginners, and extensive features for more experienced users. The rendering of simulations is handled by OpenGL, the industry standard interactive 3D graphics environment.

Gravitas is an Open Source application which means that you can download the full source code for the simulator. It is programmed and compiled using FreeBASIC.
