[Plugin] Voodoo Camera Tracker Importer - March 9, 2011

Hmm, that is a good question. This plugin was a bit of an experiment by me, but it definitely should work. I guess could you upload the .txt file here? You might need to zip it so the forum accepts it. I'll take a look at it and see if there is an oddity in the file that my script is not able to understand. Thanks,

Chris

Thanks for your answer.
I attached the file in a ZIP.

Any changes at this problem. Or is there any other possibilitie to use Voodoo in Kerkythea?

Sorry, I have not yet got to it. Perhaps this weekend I can though. Work has been unexpectedly bust the last couple of weeks - but we got a BIG project completed yesterday and this weekend I can finally relax.

No problem. There is no hurry.

floric · 23 Nov 2010, 13:52

I really don't want to ennoy but ANY changes?
It would be great if this plugin would work.

EDIT: Sorry. I studied the camera-file of the tracker and it seems to be a bug of voodoo.

Hey Floric, I am finally finding some time to look into this, and the first thing that I'm seeing is that the data is not coming out of Voodoo tracker correctly. So somehow I think you have not got Voodoo set up right. Is there any chance you could uploade the video that you are trying to track?

At first, I apologize for my pretty poor English, I don't speak it really fluently.
Whatever, I only wanted to thank you ! It's a pretty amazing work !
I'm a student in movie/photography and it's so useful for green screens !
Thanks a lot !

After some tests, I still got a question: how do you make axes generated by voodoo match these of your sketchup model?
Maybe my purpose is not really clear... (Shame on my pretty poor English ^^)
So I join a screenshot:

As you can see, there is some problem... And of course, if I simply rotate the model to make surface parallel to the ground, I lose scene views.
I'd like to make red and green axes match initial sketchup axes (and horizon to get realistic light while rendering) but I absolutly don't know how to do so ! I've been looking for solutions over the web for hours, but I didn't find anything !
No way to move horizon line in sketchup, nor to manually set axes in voodoo after tracking.
Well, I'm lost, can anyone help me, please?

Hi Sims, I've been out on vacation for a few weeks, but I'm back now.

I admit that I can't tell what it wrong with that image. It looks like it imported well to me. Could you upload the .txt file?

Or in your PM you sent me, you mentioned just trying to use another file format. If you could give me some better detail on what file format it is, I might be bale to write another version that reads their file format.

Hope you enjoyed your vacation !

First, about Voodoo, it generated a text file and it works. But as you saw, the wrong thing is that it didn't correctly find horizon... But I didn't manage to fix it.

Then, I tried Boujou. It's much more flexible and userfriendly. It generates several kind of files. But its txt is not the same as Voodoo.

You'll find attached both Voodoo and Boujou txt files from the same tracking test movie.

The picture is unclear. To me it looks like the camera path is oriented correctly with the model axes. It looks your "flat" plane and person component are the things that are wrong. The blue axis should be pointing upwards, but in your image, it is slanted, which is wrong. But I'm probably just not understanding what I'm seeing.

As for Boujou, sounds good. I'll see if I can look at it. How quickly do you need it? I'm really swamped. But I might be able to get you something simple.

sims · 2 Jan 2012, 18:35

Well, with Voodoo, something is wrong (even in 3D viewer), not only axes. It's really "skieve" as we'd say in my country. I mean, even while switching axes, it's still skewed.

I would need it for post production, so first week of February. But I absolutly don't want to bother you ! If you are overbooked, don't waste your time for me !
If I still have problems with 3D tracking, we'll work in 2D tracking, and that's it.

Whatever, thank you for interest.

Hi Chris

This plugin is great! Thanks so much for writing it.

I was wondering though if there is a way to make the imported pointcloud match the model, instead of pasting the model into the point cloud.

I have found it nearly impossible to match large models to the point cloud. A easy way to do this would be to make the camera data align with the existing models axis.

If you can alter that, I would find this plugin endlessly useful.

Thanks again.
