Abstract
The present disclosure concerns a method for displaying, on a 2D display device, a content derived from 4D light field data, based on a viewing position of a user. The 4D light field data corresponds to data acquired by either several cameras or by a plenoptic device. The method comprises: obtaining a volume in front of said 2D display device in which no disocclusions are present, said volume being defined according to optical and geometry parameters of an acquisition device that has acquired said 4D light field data, a size of a screen of said 2D display device, and an anchor plane in said content, said anchor plane being perceived as static in case of movement of a user relative to said 2D display device; determining a modified volume from said volume, comprising modifying a size of said volume, for modifying possible movements of a user positioned within the modified volume compared to movements of said user within said volume; providing means for guiding said user within said modified volume according to said viewing position of said user.
