1. A processor-implemented method for providing an image in a volumetric video, comprising steps of:
generating a set of initial faces;
acquiring a data set comprising both color data and geometric data, said geometric data comprising a set comprising at least one relevant face;
determining, from said geometric data, geometric information for said at least one relevant face, said geometric information comprising locations of vertices of said at least one relevant face;
generating from said set of initial faces a set comprising at least one geometry face, each of said at least one geometry face generated by assigning to one of said set of initial faces said geometric information for said at least one relevant face; and
rendering an image from a point of view using said set comprising at least one geometry face and said color data;
wherein at least one of the following is true:
a. for each of said at least one geometry face, said step of assigning said geometric information is effectuated by, for each vertex of said at least one geometry face, assigning to said each vertex of said at least one geometry face a geometric location of a corresponding vertex of said at least one relevant face;
b. said at least one relevant face is generated in a manner selected from the group consisting of for each relevant frame, after a predetermined time, whenever there is a coherency change in the geometry, and any combination thereof, said predetermined time being in a range from 0.01 s to 10 s;
c. selecting a number of faces in said set of initial faces to be in a range from 1 to 106;
d. selecting a number of faces in said set of initial faces to be 50,000; and
e. providing a number of faces in said set of initial faces in metadata in said texture data set.
