Welcome to the AR World ! Using "3D Superimpose", you can get the AR (augmented reality) easily enough without using the marker. First, pick a photo from your gallery, and then load a 3D model data. You can superimpose the 3D model onto the photo and save the screenshot as JPEG format. Available formats are PLY, STL-binary and RTD. Remember that the PLY is limited to a format which is exported by "Sense 3D Scanner" and "Microsoft Kinect scanner". In advance, please import the 3D model data to the application folder using iTunes, Finder or Apple Configurator2. About RTD format RTD format is the original format which is composed vertices, color and normal vector. If you want to use RTD format, you need a data conversion software "TRansRTD". It can translate the Artec 3D model data (*.obj) or the Vectra-3D model data (*.obj) into RTD.
