3D Print .obj files convert to .od?

By verschmitzt on Sat, 04/02/2016 - 15:00

Hello Vuforia fans,

 

I'm new to augmented reality, but with good tutorials and tips I have worked it out, to build my own AR app.

My problem is now, that I have a 3D printed city map. In this map I have to track all buildings for its own to give them AR informations. But how can I do this?

I have now evaluate 3 methods for that:

  1. Tracking with a lot of small Frame Markers. Because the 3D print is realy small. Maybe 15x10cm.
  2. Image Targets or a cuboid. But this really elaborate.
  3. Object Scan

It thems the best way to do this is the the Object Scan, because then I haven't any physical markers on the model. BUT, how to scan only one building on the map and don't scan others on the map?

 

For the 3D Ppint I have .obj files. Can I take them for the object target? Can I convert them to a .od file?

Thanking you in anticipation!

  

Kind regards,

I'm wondering about this too. I don't need to track anything, but am trying to figure out how to use 123d catch to create some of the content for what I'm doing with Vuforia and I know 123d catch makes .OBJ files not .OD files. Hope to get some help, thanks!

Hello,

Object Target scan resultant files (i.e. .od files) are proprietary to the Vuforia SDK. There are no tools to convert other file formats to .od, or vice-versa.

Thanks.

Well, so, how can I add an 3d object that is built with a 3D building tool.

Vuforia does not allow to build 3D model, does it?

Is there any way i can convert .obj file formats to .od? And also is there a different AR platform that will enable me to give a desired 3D model as image target instead of giving 2D images?

Hello,

To be clear with what i want to achieve is the video linked below

https://www.youtube.com/watch?v=8iVSCpk0xOw

What is see from the video is he is tracking the object or recognizing the objects using the AR algorithm and placing the content.

Can you just treat the entire 3d city as one object though? After you scan it, you can try to align the specific building (assuming within Unity3D) via the World positions.
