We have made all the integration in your documentation: http://www.wikitude.com/external/doc/documentation/latest/iosnative/setupguideiosnative.html#using-the-wikitude-native-sdk-in-swift.
This documentation explains how to perform image recognition (wtc), objects (wto), but there is no documentation of 3d models (wt3).
Someone could give us an example of how to integrate a 3D model.
Thank you very much
As I explained in my previous post, you can have 3D models with Native API but, since you are in charge of the rendering part, you need to implement 3D models from your side. This is the whole purpose of using Native API, you are in total charge of the rendering system.
