Gravitational Simulation Engine for Planets and Particles in 3D with Three.js (WebGL library)

Live Démo or : here

Earth-Moon simulation

It works well on Chrome and Safari but not good as well on IE.

Looking forward to contacting me on : [email protected]

Have a nice fun !

• SPACE : Pause state (very important !)
• Left Click : Select a ball and show information on it
• Righ Clik : Add velocity ball throught the raycast hit with the START_SPEED specified on right DAT Control panel
• ESC/ECHAP : Swith Active/Inactive control of Free Cam (for FirstPersonControls.js specifically, but little buggy)
• H : Show/Hide DAT GUI panel

Do not hesitate to add a Big Star (with bottom righ dat control GUI) on the scene center during or after the simulation.

Or change the main characteristics (Mass, direction, state, color..) of Planets/Particles in left control selection panel.

This project is a branch of this one initial : http://codeblock.at/planets/ (demo)

Initial source code : https://codepen.io/Grilly86/pen/GBaCE by https://codepen.io/Grilly86/

I would to optimize the controls of OrbitControls and Free Cam (FirstPersonControls) because it is still a bit buggy at the moment, in order to switch easier between the different kind of Controls and Cameras and have a better experience in the 3D Universe.

Another JavaScript gravity engine (in 2D with p5.js)
