This is the only a part of our project , I am still trying to upload our project to github since it's too big;you ca see the basic code in posenettest.
you can see this original project here : https://github.com/gree/unity-webview/tree/master we made a little change to it using 3d webview.
we also tried a different project here : https://github.com/digital-standard/ThreeDPoseUnityBarracuda
