APIs from RealityCap give iOS apps the ability to sense their surroundings in three dimensions. This patented (US Patent #8,976,172) sensor fusion technology combines computer vision and inertial data to give your apps accurate 6DOF device motion and a 3D point cloud of the environment. RealityCap software runs on 2011 (A5-based) and newer devices in real time, with no additional hardware or markers. Results are accurate over both short and long distances, and come with absolute scale in meters.
