3ality Technica TEAMS WITH VISION III IMAGING AND THALES ANGENIEUX




The v3 system has been very successful at adding depth and dimensionality to a standard 2D imaging and playback system. At NAB 2009, Element, v3 and Angenieux engaged in a discussion regarding what would happen if two v3 enabled Angenieux lenses were used on a Technica 3D rig. Over the past year this idea has turned into action whereby a pair of v3 equipped Angenieux lenses were mated to a Quasar 3D rig.

"There were so few 3D rigs out there that I originally considered building my own," said Chris Mayhew of Vision III. "Then we saw the Technica 3D rigs at IBC, and knew they had just what we needed in terms of flexibility, ease of mounting, and calibration. Plus, we can easily change the 3D camera configuration from a side-by-side to beamsplitter arrangement."

The results greatly exceeded expectations. For the first time in the history of live action 3D, filmmakers will have a level of depth control normally associated with 3D CGI films. In standard 3D cinematography, IO+C are used to control the amount of depth in a scene and where the subject is relative to the screen plane. Now IO+C can be set to optimize the parallax in foreground and background while the v3 system parameters are manipulated to control the amount of depth. Even with very small IO distances, greater depth and a sense of fullness can be achieved and precisely controlled. By integrating the v3 system with Technica 3D's electronics, this additional depth control can be adjusted through the Technica 3D THC (Technica Hand Controller). The results are immediate and apparent on any real time 3D viewing system so you can add exactly what is needed to enhance your storytelling or character development.

The use of stereo-paired cameras utilizing Vision III lens technology dramatically improves 3D content by providing enhanced object definition in a more natural looking environment, largely eliminating the "cut out" effect of background imagery. Logistically, Vision III also provides the advantage of being able to reduce the interocular distance, which reduces audience eye strain without sacrificing the perceived depth of the scene. The use of Vision III’s products requires no change in the 3D production cycle, and its effects are an invaluable tool for DPs, stereographers, creative directors, and producers alike.Since the onset of film, conventional lenses have used a static iris to capture visual information. While this process is effective at capturing an image, it fails to collect the detailed information that one would perceive when viewing something in person. This shortcoming can be explained by the fact that a traditional lens iris does not scan, unlike the human eye, which is in a constant state of motion. Standard lenses thereby fail to provide means to capture the additional visual cues that we perceive in everyday life.

v3D™ corrects for this problem by mimicking the scanning motion of one’s eye. The parallax information provided by a moving iris allows for a more natural, unified, three-dimensional perception on the part of the viewer. DPs and Stereographers can use v3D to create more compelling immersive content than traditional 3D can offer without requiring changes in the 3D production cycle.
