It can be used as a camera ruler or tape measure for accurate measurements on pictures and photos. This app allows user to make measurements in any defined direction and plane in 3D space. The distances and object size can also be measured by Partometer App, but Partometer3D has no constrains on the camera position relative to the measured object. The measurement plane / object plane don't have to be parallel to the camera plane.
