[RELEASED] Orbital Gravity - Newtonian Celestial Mechanics

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

Advanced planetary shader

 

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:

1. Surface (Day & Night)
2. Cloud Layer
3. Outer Atmosphere

 

Without the title rectangle the night side is better visible:

Planetary Orbits

 

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!
