This app allows you to view your own 3D CAD models with your Google Cardboard device. You can do the following things with your model:
- look at it from any angle
- explode the individual parts
- zoom

The following file format is supported:
- .obj (incl. .mtl-file) (many 3D CAD and design tools support the export to .obj files directly or via plugins)

Restriction:
The model can have as many vertices as you like but each object in the model should have less than 65,534 vertices. You can have many, many objects in each model though.
