I was using Metaio Creator for creating augmented reality applications, but now they have gotten bought out by Apple. I haven’t been able to find a suitable and economic replacement yet. I do like what Aurasma has to offer. I think I will be able to use this for the time being.
I am doing some research for adding 3D to my Aurasma auras. For these tutorials you would need Autodesk Maya (expensive) or Blender (free). I’m not sure what the file types are yet when it comes to exporting but this looks promising. For some more information on using 3D with Blender click here.
