Introduction
This script for Daz Studio takes the data from the camera tracker named Voodoo and makes it usable in Daz Studio
Second version : Now supports outputs from VooCat ( http://www.viscoda.com/index.php/en/products/voocat ),
which is Mac compatible, better and faster
Installation
A zip package containing 2 scripts ( one for Daz Studio 1 & 2, one for Daz Studio 3 & 4 ) can be found at the bottom of the page.
Unzip it in your Daz content folder. Typically this means C:/program files /Daz/Studio/Content.
Once installed the scripts will be found in your Daz Library under Studio/Content/Scripts/mCasual
Get Voodoo
Voodoo is a creation of Laboratorium für Informationstechnologie of the University Hannover
it is free for non-commercial use.
The camera tracker named Voodoo can be downloaded here :

Version History
Converting your video footage into images
Voodoo requires your video footage to be converted into a series of numbered images
here are some ways to convert your video footage into a series of numbered images
if your video is in AVI format Load it in VirtualDub, then do a "Export ... Image Sequence"
if your video is not an AVI, you could use a program like WinFF to convert it to AVI.
For the technically inclined, i personally i use FFMPEG and the following batch file.
It creates a folder named 4200 then extract the images from the file named MVI_4200.mov
the resulting images will be named img-001.jpg, img-002.jpg ... img-160.jpg
( which came from a Canon camera )
md 4200
c:\ffmpeg\ffmpeg.exe -i MVI_4200.MOV -f image2 -sameq -vcodec mjpeg .\4200\img-%%03d.jpg
An excellent place to find programs that can convert videos into images is http://www.videohelp.com/
Must be voodoo oh baby do ( http://www.youtube.com/watch?v=ukxl7YwPZq8 )
Launch Voodoo,
do a File/Open/Sequence
Browse to the folder containing your video as a sequence of numbered images
select the first one in the sequence
ex:img-001.jpg
Unfortunately, Voodoo has difficulty processing more than 200 or 300 frames
so, you could use this occasion to reduce the number of images
If your video was shot on a tripod, ( or almost as if on a tripod) then tselect the Movie Type : "rotation (Camera on a Tripod"
results are better and faster in this mode.
If instead you were walking around with your camera, select the Movie Type "free move".
Results will be better if you avoid zooming in and out while filming in "free move" mode.
While at frame 0, do a File / Initial camera
i show my video in HD720p format so i chose the HDV 720p 16:9 Type
Click on the [Track] button and wait for the (long) process to complete
Do a File / Export / Textfile
Specify a location and name for your file, i chose to save it as 4200.txt in the same folder where i store the image sequence
I elected to Export all the data points instead of the 1500 points limit
Close Voodoo
Moving on to Daz Studio
Start Daz studio
Make sure the aspect ratio of Daz Studio's view-port is the same as the aspect ratio of your video footage ex:1280x720,
This is set in Studio's Render/Render Settings menu
Make sure you are at Frame 0 on Daz's timeline
Launch mcjVooDooDaz
new in 2013: By default the AxisStyle is "Legacy", this style is the same as the original mcjVooDooDaz version work, ( see below )
if you select the "Blender" AxisStyle, mcjVooDooDaz will adopt Blender's axis system : Side-side = X, Up = Z, Forth = Y ( negated )
This will facilitate the exchanges between Studio and Blender
Click on the [Select Voodoo File ...] button
Browse up to the file you exported from Voodo
Click on the [Select First Backdrop ...] button
Browse to the first image in your video, ex: pic000.jpg
Click the [Set Backdrop For Current Frame] button
The backdrop image displayed should now be pic000.jpg
Click the [(Re)build VooDoo Camera] button
a new camera named VooDooCam should now exist
Make it the current view cam (instead of Perspective)
Click the [Build and Save point-cloud object file] button
Specify a name like \"example.obj\" as the filename
Click the [Load last saved point-cloud object file] button
Use the Hexagon import preset : 1 unit = 1 cm
Right in front of your camera there should now be
hundreds of little cones. They are the feature points
that were tracked by VooDoo while analysing your video
Optional: Click the [Play (render preview)] button
this gives you a good idea of the resulting render
New in 2013 : vertex clouds
Pressing the "Build and Save vertex-cloud" will let you save to disk the markers as an obj file.
Instead of having 1 tiny pyramid per marker it will have 1 vertex per marker ( chains of 10 vertices )
Use the "Load last saved cloud" button to load the vertex cloud.
The vertex cloud will look like a mess
One way to make it look like a vertex cloud:
- Select the vertex cloud
- add a D-form to it
- make the material of the vertex cloud fully transparent,
- set its specular color to black ( if it's not )
- select the D-Form
it should now look like this
The other way to make the vertex-cloud look like a vertex cloud is to use mcjTracer
The mcjTracer plugin is only available for Daz Studio version 3, but should soon be ported to DS 4.5
- Select the vertex cloud
- create an mcjTracer (from the Studio's 'Create' menu)
- in mcjTracer's parameters tab, make the edges invisible
it should look like this
Use the cones to position your characters and props
Click the [First Rendered Image] button and
specify the name and location of the first image to be
rendered, example: \"C:\\VooDooDazOut\\pic.jpg\" ...
... will produce the series of images:
pic0.jpg, pic1.jpg ...pic149.jpg in the VooDooDazOut folder.
Click the [Render as Numbered Images] button.
mcjVooDooDaz will render each frame with the proper backdrop
Convert the resulting series of images into a video file
using a program like virtualDub, ffmpeg etc .."
