particles

[Usnul]

have you considered switching to
https://github.com/squarefeet/ShaderParticleEngine ?
or something else that is more performant than SPARKS in its current state
I've observed that in the current state threenodes can't handle more than 2k or so particles without noticeable drop in frame rate. Compare that to 60FPS on ShaderParticleEngine demo with 360k particles. This is not criticism to threenodes, simply a fact of life when dealing with a single-threaded nature of javascript. Highest count of animated particles using pure JS solution i've seen at interactive rates was about 20k using webworkers (updates happen at a different rate than rendering actually).
