Abstract
A method for real time construction of a video sequence comprising a modelled 3D object is provided. The method comprises pre-calculating data representative of a first image of a three-dimensional environment and a first associated depth information. A live calculating of data representative of a second image representing the modelled object on which is mapped a current image of a live video stream, and a second depth information associated with the second image is performed. The sequence is composed by combining the first image and the second image according to the first and second depth information.
