I have been working allot with particles recently, attempting to make a particle emitter.

Initially i wanted to start with 0 particles and keep adding them upto a maximum value, i was pushing Vertices onto the geometry like this:

this.particles.geometry.vertices.push( vertex );

However this didn't seem to work if i did it after the particle system had been added to the scene.

Eventually i just created a fixed number of particles and emitted them from a point, it looks ok, but im not 100% satified.

Another solution would be to be able to set the Alpha value for each particle. Currently it only seems possible to set the opacity for the whole material, affecting all particles.

I was using vertex colors for each particle, but they are only RGB. Would it be possible to make vertex colours RGBA in future? Then i could create all my particles and set them all to transparent, and begin blending them in as necessary.
