Overview :
Gravity Engine provides a complete physics toolset for space games. Add stars, planets, and spaceships that interact via n-type gravitational bodies, or “on rails.”
Highlights:
- Design orbits by shape and see their paths in the editor and scene
- Manual orbit changes with clickable handles
- Orbit transfers/rendezvous from any orbit to any orbit
- Rocket engines with staging
- Model of Earth atmosphere
- Solar system builder: add any object in the JPL database
- Use real-world units (km/AU, kg)
- Full support for particles
- Highly accurate double-precision physics, with a choice of algorithm/Kepler evolution
- Control of overall evolution speed, scale and CPU use
- In-scene extensible command line console for development and debug
- Change gravity to any force you design
- No programming or math is required.
