Simulation of gravitational forces between planets with user interaction. Provides interface for easy creation of your own scenarios of cosmic movement.
Every cosmic system can be loaded and saved by using menu bar on the left side of application. Simulation can be paused and resumed - depending on what you need.
Application handles mouse and keyboard events. Click left mouse button to place a planet (don't release!) and then move mouse somewhere else to adjust starting velocity of the planet. To change size (and mass) of the desired object use combination of Left Ctrl + mouse scroll. Be careful - size of each planet is limited!
To move the view of your own planetary system use keyboard arrows. If you want to zoom in or zoom out - use mouse scroll.
Environment configuration is editable via config.j3x file in data directory. Feel free to modify it.
Build is as simple as it is possible [CMake]. Use provided in package build_and_run.bash script to build and open window with application. Additionally, run.bash script runs already builded Gravity app.
- C++14 compiler
- CMake >=3.6
- SFML >=2.4 library
- TGUI 0.8.5 library
- GTest - latest master
If you want to build unit tests - run build_and_run_tests.bash script in main directory.
Gravity consists of ODE solver (Runge-Kutta 4th order) to determine movement of system of planets. Each planet is computed separately which gives a simple touch of reality. Planets collide with each other, so every meeting ends with destruction and momentum conservation.
Future development is described in Issues. Have fun!
