Gravit is a gravity simulator which runs under Linux.





Gravit is a gravity simulator which runs under Linux, Windows and Mac OS X. It's released under the GNU General Public License which makes it free. It uses Newtonian physics using the Barnes-Hut N-body algorithm.

Although the main goal of Gravit is to be as accurate as possible, it also creates beautiful looking gravity patterns. It records the history of each particle so it can animate and display a path of its travels.

At any stage you can rotate your view in 3D and zoom in and out. Gravit uses OpenGL with Lua, SDL, SDL_ttf and SDL_image.

Here are some key features of "Gravit":

· It looks pretty :)
· View the simulation in 3D using stereoscopic imaging!
· Can be installed as a screen saver in Windows
· You can record, then play back at any speed
· Stores every particle's position for every frame in memory
· Compresses history when needed, for very long recordings
· Mouse controllable rotation
· Console with script execution
· Colours can be based on mass, velocity, acceleration, momentum or kinetic energy
· See an octtree being created in real-time
· Save/Load functionality
· Update display/input while recording a frame

It is written in C and uses Lua, SDL, SDL_ttf, SDL_image and OpenGL.
It uses the Barnes-Hut Algorithm (with room for optimisation).
Gravit was called Graviton, but i changed the name because someone already used Graviton for their project!

What's New in This Release:

· Console tab completion
· Added Q and W keys for lowering and increasing frameskip
· added S key to toggle stereo mode
· added D and F to decrease and increase stereoseparation
· Reorganised F1 help
· Added stereoosd to make the osd shown in stereo (but stretched for now)
· When drawosd is 0, the console and console log will be displayed when you activate the console
· Fixed a bug with the octree (and others) sometimes not being drawn
· Fixed colour scheme bug with one colour
