[Bf-python] Extracting cloth vertices position

[fmart]

Hello,

I'm trying to obtain all vertices global position of a piece of cloth 
after colliding with a table. My simulation starts with a plane as a 
piece of cloth and another plane below as a table with the Collision 
modifier.

To obtain all the data I need I'm using the following code (I've the 
cloth selected):

import bpy
current_obj = bpy.context.active_object
print("="*40) # printing marker
for face in current_obj.data.polygons:
	verts_in_face = face.vertices[:]
	print("face index", face.index)
	print("normal", face.normal)
	for vert in verts_in_face:
		local_point = current_obj.data.vertices[vert].co
		world_point = current_obj.matrix_world * local_point
		print("vert", vert, " vert co", world_point)


The simulation works well, I think the code also works well. However, 
all that I obtain are vertices global position of the cloth in the 
initial position, it doesn't matter whenever I pause the simulation.

Is there any possibility to obtain cloth vertices position after a 
collision?

Thanks!
