LED cube simulation

I currently try to make a simulator for a LED cube. I searched for ways to achieve the effect of a shining light like a LED, but I can’t seem to find a reasonable approach. I think it is possible with ParticleEmitter but Particles have by design a lifetime and are spread randomly in a EmitterShape.

What do you suggest to use as LEDs instead?

A glowmap?

a glowColor should be enough really


go to bloom with a glow color (reading the whole document won’t hurt though ;))

Ok in the tutorial I saw only the green point with fuzzy border and didn’t think it would work, but the result is better than expected.

Maybe the colors have to be brighter because the Bloom works for bright objects.
