How to convert Blender blend (or obj) file to Qualcom Vuforia .h file

Question

I'm developing an iOS app with augmented reality using Qualcomm Vuforia and I have difficulty in understanding how to create 3D models from Blender (or other softwares). All the examples use .h files with the coordinates of the vertices to generate i.e. a teapot. I can not find documentation useful for me. Is there a tool to convert .blend or .obj files to .h (OpenGL ES)?

thanks

Answer 1

I developed a script called mtl2opengl that does exactly what you need, based on the project obj2opengl. The script works with .obj and .mtl files, which I think can be exported straight from Blender, and produces .h files with vertex data. I use it extensively in my iOS augmented reality applications (though I haven't used the Vuforia SDK yet) and the accompanying resources include a sample Xcode project too. Hope it helps!

You should check out BlenderVuforiaExport (developed by a coworker of mine) here:

https://github.com/StickyBeat/BlenderVuforiaExport

It exports objects from Blender to the same .h-format used in the Vuforia example project.

I don't know much about vufoia, but here are two answers about using blender to get 3d models and displaying them on iPhone. These may help you.
