The Holographic Video Player has two Settings panels, explained below.


The panel above contains adjustable controls for how the 3D video is displayed. As shown on the Demo Videos page, foreground objects can be attached or separated from the background (Embossed or Layered). The wireframe would ordinarily come from the video scene, although the Rotating Bump is still included for experimental purposes.

Under Background, the user can use the existing background (Normal), replace the background with a green screen (Empty), or specify a new background under (Image). The Fill-in option causes the software to buffer background information behind occluding objects so that no holes are seen in the scene model when navigating or looking around foreground objects.

Ambient Color: this check-box causes the panel surrounding the movie to continuously change color to match the predominant color in the movie, as we consider features adding to the immersive experience.

Finally, in the View section the user can choose a dynamic wireframe (3D View). The could also specify binocular windows of 3D video, or the red-green layering for 3D glasses (Anaglyph). It is possible to set the colours of red and green/blue to match particular coloured lenses. Also, there are controls for eye separation and convergence, in case needed for a particular viewing situation or head-mounted display.

 

The Splitter Settings control the image processing in the software. The default values are used in most cases. There are pop-up explanations for each control on mouse-over in the panel, although the most common adjustments will be explained here.

Z Model: This refers to the nature of the camera movement, which helps to minimize geometric calcualtions. Anchorman Mode is when the camera is stationary, as in a new broadcast. There is also Parallax Mode, when the camera is moved laterally (which is the most effective way to highlight relative depth for the software). Also, there is Generic Mode when any type of camera movement is possible.

Max Z: This is an adjustable setting to control how far out the wireframe extends. The Inflate check-box specifies whether foreground objects should be on a flat plane (there is no possible distortion this way), or rendered in 3D. The Pop-on-Y check box specifies that vertical (Y-axis) movement should also be used to detect depth information.

Confirm Before Popping: This specifies the number of frames of motion detected before the wireframe should be adjusted (out) or put back (in). This is affected to some extent by the speed of the computer used. If there is a trailing edge on moving foreground objects, move the In value closer to 1 frame. If an object pops in and out rapidly, change the settings to only pop out if the foreground depth is confirmed over about 3 frames, and only to set In after confirming for 3 frames.

Finally, the large buttons on the bottom right are shortcuts for a variety of default settings. Note also that freezing the white balance and gain on a web cam or DV camera will stop fluctuations across frames, and make the depth perception more smooth and stable.
