[RELEASED] Orbital Gravity - Newtonian Celestial Mechanics

2078484--135736--orbital_g_forum.png
Orbital Gravity is a complete Unity project. The main part of the project is the implementation of the famous Newtonian celestial mechanics.

It’s a plain gravity driven simulation of celestial body movements. The planetary movements are not based of any geometrical astronomy.

Key Features

  • Fully adjustable Physics
  • No predefined Kepler Path Motions
  • Dynamic Time Scaling
  • All Planets of the Solar System
  • 3 Levels of Detail
  • Hi-Res PBR Textures
  • Advanced Atmosphere Shaders
  • Complete 2D & 3D UI
  • Source Code included

Very nice looking shader, does the earth include man made lighting when in dark.

Yes! All images are taken directly out of Unity.
Planet earth has basically a 3.5-layered body:

  • Surface (Day & Night)
  • Cloud Layer
  • Outer Atmosphere

Without the title rectangle the night side is better visible:

I have a question about the feature set: what are “Kepler Path Motions” and why is it good not to have them?

That means that the bodies (planets, even the sun) are not following a predefined path. The movement, more precisely the force that leads to it, is calculated based on the specified mass and distance (-> gravity). Each participant of the simulation affects the others (superposition principle). Changing the mass of a body will change the path of all others.

Hope that helped! :slight_smile:
