ADVANCED LIGHT FIELDS FOR AUTOSTEREOSCOPIC VISUALIZATION IN 3D (ALFI3D)

Auto stereoscopy is being considered the next technological step in image and graphics
visualisation, allowing 3D-visualisation in a natural and non intrusive way. In this context, Light
Fields are part of a methodology that is becoming as one of the most feasible techniques to supply
in an efficient way the views an auto-stereoscopic display needs. Thus, Light Fields to store the
radiance information of a scene are an alternative to traditional rendering techniques, which is
emerging with strength in the context of auto-stereoscopy.

The main objective of this project is directed to the development of new Light Field models and
techniques; which would allow the calculation and utilisation of light fields in auto-stereoscopic
displays (natural stereo view), where several users can observe the device and perceive the 3D
structure of the scene from different points of view in a simultaneous way, without needing any
intrusive accessory, e.g. glasses.
Therefore, this project will investigate methodologies for Advanced Light Field Models, partially as a
continuation of the already finished ALF project (TIN2005-08863-C03). During the development of
ALF project, new challenges and research lines did arise, which are needed to achieve a feasible
solution that allows the use of Light Fields in applications demanding non-structured, dynamics, nonuniform
or navigable Light Fields. These technologies, still in an incipient and emerging state, have a
huge potential in high impact application and socio-economic areas like 3D television or interactive
holographic visualisation for design and visual presentation of products. The development of the
basic technology for these applications is going to be the fundamental aim and motivation of the
research proposed in this project.
