The following is simple example of reading a mesh’s animated vertices data.
Note that accessing an model’s animated vertex locations requires reading the model’s evaluated (deformed) mesh state per frame.
For that reason a new bmesh object is initiated per each frame with the the model’s updated dependency graph.
import bpy
import bmesh
obj = bpy.context.active_object
frames = range(0,10)
get the object's evaluated dependency graph:
depgraph = bpy.context.evaluated_depsgraph_get()
iterate animation frames:
for f in frames:
bpy.context.scene.frame_set(f)
# define new bmesh object:
bm = bmesh.new()
bm.verts.ensure_lookup_table()
# read the evaluated mesh data into the bmesh object:
bm.from_object( obj, depgraph )
# iterate the bmesh verts:
for i, v in enumerate(bm.verts):
print("frame: {}, vert: {}, location: {}".format(f, i, v.co))
