Abstract
Methods, devices and data stream are provided for signaling and decoding information representative of restrictions of navigation in a volumetric video. The data stream comprises metadata associated to video data representative of the volumetric video. The metadata comprise data representative of a viewing bounding box, data representative of a curvilinear path in the 3D space of said volumetric video; and data representative of at least one viewing direction range associated with a point on the curvilinear path.
Claims10
A method for rendering a volumetric video according to restrictions of navigation, the method comprising decoding metadata from a data stream comprising video data representative of the volumetric video, the metadata comprising:
- data representative of a curvilinear path in a three-dimensional (3D) space of the volumetric video;
- data representative of at least two 3D points of view on the curvilinear path associated with a viewing direction range;
- and data representative of a viewing bounding box centered around one of the at least two 3D points of view;
- and
- rendering the volumetric video from a point of view within the viewing box associated with a first point of view of the at least two points of view in a limit of the associated viewing direction range.
A device for rendering a volumetric video according to restrictions of navigation, the device comprising a processor configured for decoding metadata from a data stream comprising video data representative of the volumetric video, the metadata comprising:
- data representative of a curvilinear path in a three-dimensional (3D) space of the volumetric video;
- data representative of at least two 3D points of view on the curvilinear path associated with a viewing direction range;
- and data representative of a viewing bounding box centered around one of the at least two 3D points of view;
- and
- rendering the volumetric video from a point of view within the viewing box associated with a first point of view of the at least two points of view in a limit of the associated viewing direction range.
