Although our homemade 3D projection is not technically a hologram, through its production, we were able to explore the general concept behind holographic projections and the mechanics of utilizing wave properties of light to generate a perception of depth. In particular, in order to create a holographic effect, the projected video must contain four trapezoids of the same video rotated and spliced to create a ring. By placing the funnel created by trapezoidal pieces of perspex over the screen playing the video corresponding to the appropriate trapezoids, each of the trapezoids pass through their respective perspex trapezoids, combining to create a single projection above the phone screen that appears 3D. The usage of four videos and four reflective screens from four sides create an illusion of depth, while the angled placement facilitates the "pop-out" effect.
If we were to repeat this project, we would look for more refined ways to cut out the trapezoidal perspex pieces, as well as use clear tape rather than Krazy Glue. We would also shoot our video in a completely dark room and use a camera suitable for dark settings. It would also be interesting to create our own holographic video and perhaps explore the possibility of using a video that doesn't have a black background.
Is this a good/useful/informative piece of content to include in the project? Have your say!
