I was working on a online solution via php,
(something like "upload voodoo file" -->"get icarus file")
maybe that can work,
Hi Matthias :
With the method I used for the recent project sent here,
most of the work is still done in Icarus . Voodoo will not
accept video data so the video must be converted to .tga's
first , but then it is one click (Track) and the camera's
Focal length is quickly know .
That Focal Length goes into Icarus and then all that is
required to do is load the Video and :
1) Set input and output frames (start & end of video)
2) Push the 'Auto Track' button
3) Push the 'Calibrate' button
4) Export the data as 'Human Readable'
It's simple and it works very well . Not quite as simple
as Voodoo's 1 button method , but the main thing is accuracy
and this method is accurate .
The reason I was looking to Voodoo was because I was having
great difficuty with Icarus's method of determining the Focal
Length . It was hit and miss and output was only "in the ball
park" type of data that took a lot of work inside RS3D to mass-
age into a workable scene . Wasted several days experimenting .
Now , for video I shoot with my own camera I can just input
that know Focal length in Icarus and ... Presto ! Out comes
accurate 3D data . The Icarus to RS3D connection is excellent
from what I can see , and this 2 stage method (only when req-
uired) works very well and is very quick too .
I guess a tutorial is in order , but I am busy trying to
create stuff right now . Preferably , there is Syntheyes ,
which really is an excellent 1 step program and not that
expensive , with very good tech support too .
but at the moment
there is no time on my table to finish this.

Ah , I wondered where you got to ? Sounds like you are
expanding your horizons ? Very good . Good luck with your
endeavors .

Hi :
Looks like the Voodoo-to-Icarus idea of mine was a dead
end . Might be possible but looks like a lot of work to do
since the Voodoo data must be multiplied by factors and
same with CAHV etc .
Anyway , here's a RS3D file using the Voodoo tractor
images (that install with the program) but have been run
through Icarus and then imported into RS3D .
http://studiodynamics.net/list/tractor-cameramatch.zip
1.7 MB's and includes the images (in jpeg format for
net usage) . Place the jpegs in your texture folder or
redirect RS3D (you may get error messages) .
The scene is large and uses a high zoom camera so a
trick is to just drop the whole root into the viewport
if you are having trouble navigating . Be sure to drop
the Icarus camera into the viewport to see the actual
tracking results . There is an overhead camera for
working on the scene .
Also , use the image object backdrop for best per-
formance by selecting wireframe mode , and turn that
off (when working on the scene) by using OpenGL mode.
To get a feel for the scene , drop the Icarus camera
into the viewport , then drop the root into the viewport.
Now move around with your mouse to see the entire scene
from an angle . Note the placement of the Backdrop image
and the camera's distance from the 'Feature' datapoints.
A very simple test animation is here and is included
with the zip file . Load it into Xnview (.com) to view
it in slow motion or frame by frame .
