1. A method for live construction of a video sequence, said sequence comprising an object modelled in three dimensions, wherein the method comprises:

  • pre-calculating data representative of at least one first image of a three-dimensional environment and a first item of depth information associated with said image,live calculation of;

    data representative of at least one second image representing said modelled object on which is mapped a current image of a live video stream, said current image forming the texture of the modelled object, the mapping of the current image on said modeled object using only texture data of the current image, anda second item of depth information associated with said at least one second image, andlive composition of said sequence by combining said at least one first image and at least one second image according to said first and second items of depth information.
