[SOLVED] python script per frame when cycles is rendering?

Coding Python Support

I can execute one python script per frame (main loop), when Cycles rendering are working?.
Thanks.

I want to change the mesh like this (per example pseudo code):

i = 0
while (cycles is rendering){
    bpy.data.objects['Cube'].data = bpy.data.objects[Cube.i].data
    i += 1
}

I would like try to do a lod (Level Of Detail) script for Cycles.
I need measure objects and camera per frame.
