Where can one find such an effect?

Question

WebGL

To understand for a long time, it looks very nice.
Having looked at them in the inspector, they use 2 particle systems ( glareParticles & flareParticles ), and animate the textures, here is one of them
demo . I think that you can’t do your own in half an hour here. Does anyone know how to quickly pull this beauty, or where can I find a similar one for threejs?

Answer 1

But this is for whom in each demo?
