Let’s start looking at video recorded with HoloFlix on an actual Volume 3D display device and compare it to regular 2D video so we can better understand how this new medium works and why its different. Above is a video showing how the video appears on the volume with the physical camera rotating around the device. Below are 6 still images showing the image volume from 6 different angles.
Occlusion
Volumetric 3D displays have many positive visual attributes — however one that people skilled in the field often talk about is the lack of occlusion in the technology — that everything will appear transparent and therefore no object closer to the viewer will be able to obscure visual information behind.
But check it out! As we rotate from the right to the left side of the volume display we can see the makeup artist obscuring his client — or rather we cant see his client — but as we move around she comes into view from behind him. That’s occlusion! Because he is wearing white it lights up so much of the volume that you cant see anything past it… so this wouldn’t work if he was wearing a black or maybe even a grey shirt. Near the end of the video as the camera looks down on the slices from above — you can get a relative sense of how bright the man’ shirt really is.
TIP: If you need to have occlusion in your scene — adapt wardrobe, makeup, props and setting accordingly i relation to brightness and depth stacking order
Parallax
Check that video out again — you can look around stuff! So just as we spoke about the makeup artist occluding his client — depending upon what angle we look into the display at, we see the position of the people and objects in it shift in relation to our head and gaze.
