3D Gravitation Simulations
To get the 3D effect, look at the two orbit
system cross-eyed so that they appear as one.
Select an "Instance" and click "Start".
Overview:
This applet provides 3-D simulations for the N-body problem in which N masses
are allowed to interact gravitationally. The motions are computed using
a midpoint integration rule.
Controlling the Simulation:
- dt is the time increment in years (so 0.003 is approximately one day).
Give a negative value for dt to run the simulation backwards.
- Warp:
The most time consuming part of the simulation is painting the window.
Parameter "warp" indicates how many simulation time steps are performed
per repainting. Large warp factors make the simulation run very fast.
- You can Pause the simulation, change dt and/or warp
and then press
Apply or Play
to restart the simulation using these new animation parameters.
