This Page is the documentation of trying to simulate flying on other planets in flightgear.
I located the files responsible for atmosphere and gravity in the flightgear source code.
File Locations
The files are in /src/Enviroment
The names are
atmosphere.cxx
atmosphere.hxx
gravity.cxx
gravity.hxx
Simulating gravity
After looking at the source code in the atmosphere and gravity files I decided to start by adjusting the gravity to that of titan because that planet is most likely able to be flown upon.
I changed lines 48-52 to
// Geodetic Reference System 1980 parameter
- define A 6576.0 // equatorial radius of Titan
- define B 6576.0 // semiminor axis
- define AGA (A*1.352) // A times normal gravity at equator
- define BGB (B*1.352) // B times normal gravity at pole
from
- define A 6378137.0 // equatorial radius of earth
- define B 6356752.3141 // semiminor axis
- define AGA (A*9.7803267715) // A times normal gravity at equator
- define BGB (B*9.8321863685) // B times normal gravity at pole
