How to make a star with three.js like Chrome Experiments 100,000 stars

Question

I hope this is the right place this time, but I am trying to figure out how to use three.js to create a star the way the chrome experiments 100,000 stars was done. I tried looking into the source code but it is extremely difficult to decipher, it seems to be many parts, I have tried using textures, and I don't know how to get the glow or the halo around the sun, I would appreciate any assistance from someone with knowledge on how this was done.

Answer 1

Here is an example of a halo-style glow effect using shaders:

It is still a work in progress -- panning or zooming will change the appearance of the glow, but perhaps it will be enough to be of assistance.

Hope it helps!
