A method and technical equipment for encoding, where the method comprises at least receiving a video presentation frame, where the video presentation represents a three-dimensional data in the form of mesh data (); separating from the mesh data information on vertices, wherein the information comprises at least connectivity data defining connections between vertices (); determining parameters relating to said connectivity data (); encoding the parameters to a first bitstream as a video component (); and storing the encoded first bitstream for transmission to a rendering apparatus (). In addition to encoding, also decoding is disclosed.

There are disclosed various methods, apparatuses and computer program products for video encoding and decoding. In some embodiments the method for video encoding comprises obtaining compressed volumetric video data representing a three-dimensional scene or object (); capsulating the compressed volumetric video data into a data structure (); obtaining data of a two-dimensional projection of at least a part of the three-dimensional scene as seen from a certain viewport (); and including the data of the two-dimensional projection into the data structure ().

Apparatus, a method and a computer program for omnidirectional video

A method comprising: authoring a plurality of sets of media tracks comprising at least a first set of media tracks and a second set of media tracks into a media file format, wherein a subset of tracks of the first set comprises alternate data for each other and a subset of tracks of the second set comprises alternate data for each other; and including, in or along a bitstream comprising a media file including or inferring said media tracks, an indication that said subset of tracks of the first set are alternatives to each other and said subset of tracks of the second set are alternatives to each other upon playback of the media tracks.

Apparatus, a method and a computer program for video coding and decoding

An apparatus comprising circuitry configured to: obtain a three-dimensional model comprising at least one patch, at least one geometry component, at least one occupancy component, and zero or more texture components; subsample the at least one geometry component of the at least one patch of a three-dimensional object at occupied positions using a subsampling criterion; define respective search windows around the respective occupied positions; select respective salient points relative to the respective occupied positions within the respective search windows; triangulate the salient points to approximate a shape of the three-dimensional object; detect zero or more triangles that overlap with at least one unoccupied pixel; split the zero or more triangles that overlap with at least one unoccupied pixel until no triangle overlaps with the unoccupied pixels; and add zero or more additional triangles close to a border of the three-dimensional object to generate a resulting mesh signaled to a decoder.

V3C patch remeshing for dynamic mesh coding

A method comprising: providing a 3D representation of at least one object as an input for an encoder (); projecting the 3D representation onto at least one 2D patch (); generating at least a geometry image and a texture image from the 2D patch (); generating, based on the geometry image, a mesh comprising a number of vertices (); mapping the number of vertices to two-dimensional (2D) coordinates of the texture image (), and signalling said 2D coordinates of the texture image to be applied to the number of vertices of the mesh in or along a bitstream ().
