Is there a faster/better way to keyframe tabulated position data?

I’m using Blender to animate STL objects, by importing tabulated data and inserting keyframes for each location and orientation. For small simulations, this works fine. However, for larger simulations, e.g. ~20,000 rows of data, Blender uses to much time (not responding)…

Is there a better way to do this, or am I doing it wrong ?

## after data-import, object-calls and setting first and last frame-nums of the scene
for i in range(0,n):
    obj.location = (x[i], y[i], z[i])
    obj.keyframe_insert(data_path = 'location')
    obj.rotation_euler = (rx[i], ry[i], rz[i])
    obj.keyframe_insert(data_path = 'rotation_euler')

Yeah, in fact the scene.frame_set(i) forces a scene update which can be very long for 20 000 rows.
What you could do is removing this line, and use the frame param in the obj.keyframe_insert () function (I don’t remeber exactly the name but there is a param for specifying the frame where to insert keyframe)

See you :slight_smile: ++

Yes, you’re right, after data path you just add frame number, like this:
obj.keyframe_insert(data_path = 'location', frame = 1)

Thanks for your reply tricotou. I tried removing the scene.frame_set() function, and implemented obj.keyframe_insert(data_path = 'location', frame = i), but unfortunately, it did not make much difference.
I guess this method of animating objects is suitable only for small sets of data.
