Voodoo to Blender 2.55 problem..

Coding Python Support
1

I’m a newbie about Blender so pls excuse if this is a banal issue, i did a series of searches and havent found my solution…
When i try to open a Voodoo tracking python export i saved, it returns the following error:

AttributeError: ‘Scene’ object has no attribute ’ set_frame’
location: <unknown location>:-1

Below is a part of the exported script itself:

blender export (blender version 2.5x and higher)

created by voodoo camera tracker - www.digilab.uni-hannover.de

Creation date: Mon Dec 20 18:33:23 2010

USAGE: load this python script into Blender’s text editor and execute the script with ALT-P

use the ‘voodoo_render_cam’ for rendering your scene

use the helper object ‘voodoo_scene’ to rotate, translate and scale the scene

import bpy
import mathutils
import string
import math
scene = bpy.context.scene
dummy = bpy.data.objects.new(‘voodoo_scene’, None)
dummy.location = (0.0, 0.0, 0.0)
dummy.rotation_euler = ( -3.141593/2, 0.0, 0.0)
dummy.scale = (0.2, 0.2, 0.2)
scene.objects.link(dummy)

data.lens_unit = ‘DEGREES’
vcam = bpy.data.objects.new(‘voodoo_render_cam’, data)
vcam.location = (0.0, 0.0, 0.0)
vcam.rotation_euler = (0.0, 0.0, 0.0)

scene.objects.link(vcam)
vcam.parent = dummy
data = bpy.data.meshes.new(‘voodoo_FP3D_cloud’)
mesh = bpy.data.objects.new(‘voodoo_FP3D_cloud’, data)
mesh.location = (0.0, 0.0, 0.0)
mesh.rotation_euler = (0.0, 0.0, 0.0)
mesh.scale = (1.0, 1.0, 1.0)

I get the same error:-

Traceback (most recent call last):
File “test.py”, line 42, in <module>
AttributeError: ‘Scene’ object has no attribute ‘set_frame’

location:<unknown location>:-1

I guess something has changed in Blender or the Voodoo export needs updated.

I had a same problem with the officiele 2.55 the problem is the api changed but lukily its a easy fix
just replace in your saved py file every

“set_frame”

with

“frame_set”

example:
scene.set_frame(1)
to
scene.frame_set(1)

and then try to run it

at least it fixed for me… good luck

It doesn’t seem to work for the most recent Blender build.

The import script you link to gives this error:-

Traceback (most recent call last):
File “/home/organic/install/linux2/2.55/scripts/addons/io_import_voodoo_camera.py”, line 220, in invoke
wm.add_fileselect(self)
AttributeError: ‘WindowManager’ object has no attribute ‘add_fileselect’

location:<unknown location>:-1
and the change you suggested imports the camera, empty and point cloud successfully, but the camera orientation is wrong.

I guess everything will be updated and working eventually though. I don’t intend to complain about anything not working until Blender is finished, stable and released. :smiley:

Many thanks to fobos, replacing “set_frame” did it!! I just composited in AE a basic Blender render and it looks…well it looks like s*** but that’s my own fault, its just a cube tracked in front of my house… :smiley: … The tracking works though…

Btw…hey organic…camera orient looks nice to me…

add_fileselect now is fileselect_add

7

That’s funny because Blender tolds me:
AttributeError: ‘WindowManager’ object has no attribute ‘fileselect_add’
It occurs in io_import_scene_mhx.py, line 2446, when I try to import a .mhx-file.

Cool, I changed in the script to add_fileselect and it works! :slight_smile:
Thanks again!

frame_set work for me to get the tracking in BUT how to fix the problem with the camera orientation after you bring in the voodoo tracking ?

I’m pretty sure the camera orientation thing is a bug in Voodoo itself.

and since there’s no way to get a gander at the source…
