How to emit particles evenly within single particle setting

Question

How to emit particles evenly from verts / faces within single particle setting?

For example, for the default cube, I want to emit 80 particles in 10 frames, in other words, each vertex should emit 1 particle together per frame. (Note that this is a simple case to show what I'm talking about, not a specific one)

Answer 1

Blender Internal Render with Particle Info Node for Material Nodes

• Image below. 16 Layers of Particles Systems modified with a Python Script. Vertices of a Cube.

• Image Below. An image meant to be more readable with the particles placed in a plane. Pulsed and Batch alternating. Spiral motion is a typical consequence of the Particle System and very little effort of the Python Script.

• Image Below. Particles with Turbulence. One Force example.

• Image Below.

Technique

In the image above are 4 particle systems. You may use 10. Each Emitter particle system is copied via the Keystroke Shift+D. User preferences allows particle system to be duplicated with fresh unique copies. See user preferences Editing/Duplicate Data and enable Particle System Duplication. Of course an object can have multiple particles systems. The script assumes 1 per object for no particularly sound reason.

• If you can copy a mesh easily you can copy a mesh with a particle system easily.

• The N particles system has the [Start] and [End Value] set to different numeric value M. M >= 0 and M < N in the simplest case. See Script below.

• Copying Emitters and Manual modification of the values takes (log N + N ) steps.

• Example is Verts emission. Faces emission is an easy switch.

• Clearly if you wanted ((vertex or face) * large number) particles then a script could modify the particle system [Start] and [End] values. (frame_start, frame_end)

• The Emitters are in a group for selection convenience.

Script

• Use at your own risk. Standard Disclaimer. Please test and improve.

• Select the group of Particle System emitters before running the script.

...

import bpy 
import datetime
import math

def delay_particles():
    print("Delay Particles")
    print(datetime.datetime.today())
    print(datetime.datetime.now())

    so = bpy.context.selected_objects
    limit = (len(so))
    n = 0
    for x in range(0,limit):  
        so[x].particle_systems[0].settings.frame_start = n
        so[x].particle_systems[0].settings.frame_end = n
        n = n + 1

delay_particles()

Answer 2

Just select emit from verts under particle settings.
