A projecting apparatus is disclosed, which is disposed within a space defined with first, second and third imaginary planes perpendicular to one another and includes a light source, a prism, a reflecting mirror, and a reflective light valve. A first plurality of microphone signals is obtained by a first microphone array. The metadata of the media files may be searched by one or more terminals. The selected shearing value satisfies various moir\xe9-free conditions associated with the identified frequency vectors and is capable of being selected for multiple halftone screens. The image data collected from this series of images is then processed by relatively simple matrix operations to determine the location of each camera pixel in three dimensional space.
