www.holofil.com HOLOFIL Android 3D model viewer lets you load a random 3D model (obj/fbx/dae/3ds/ply/formats) from the local storage and lets you do actions such as rotate, move, zoom to explore them further. You can also control the lighting of the model and decide the background color to customize it further. One important feature is the ability to load animated 3D models in FBX format and control them while the animation is being played in the model viewer.
There are two new features that are introduced in the Premium paid version that are locked in this version. One of them is face tracking. In face tracking the 3D models will turn as you move your face seamlessly to give you control on the movement and its sensitivity. The other feature is export of simple 3D animations such as turn-table animation. Both these features are available in the paid version, and require audio and video access to enable the recording of video and camera for face tracking. We do not store any of your information using face tracking to be sure of the privacy concerns.
It supports high polygon models upto 1M polygons on latest mobile hardware, but if you have really high poly models, try to reduce the polygons and load them in the application. Your feedback is most welcome.
