This is an example of Three.js ‘galaxy’

Well, the first idea was to use planes as these ‘dots’ in galaxy (as it has lowest triangles count) but still, if I were to use like 40,000 points…

I only need these two functions out of this:

  • Make these clickable (pickalble)
  • Max 5 colors needed across all different points

Any ideas?

You can achieve it with transform feedback. Example:

Wow, it looks amazing. But how should I pick a particle, or on this case it would be considered as picking a “vertex” ? Next question is how shall i assing some data/text propery to it, since each particle is not a new entity.

There is also this one where the simulation is done on the CPU and not the GPU, which might be easier to understand and modify: PlayCanvas Examples
