Simulator or Emulator? What is the difference?

Emulation is the process of mimicking the outwardly observable behavior to match an existing target. The internal state of the emulation mechanism does not have to accurately reflect the internal state of the target which it is emulating. Simulation, on the other hand, involves modeling the underlying state of the target. The end result of … Read more

Is it possible to make realistic n-body solar system simulation in matter of size and mass?

I did program sol system simulation too so here are mine insights: rendering I use OpenGL with 1:1 scaling. All units are in SI so [m,s,kg,…]. The problem gets started with Z-buffer. The usual Z-buffer bit wide is 16/24/32 bit which is nowhere near what you need. I am rendering from 0.1m up to 1000 … Read more
