1. A kit comprising:
a receptacle for receiving a real object on which a marker is provided; and
information for obtaining a computer program to execute a method for applying texture in augmented reality, the method comprising:
acquiring, by an image acquisition module, a real-world image on which the real object and at least one portion of the marker linked to the real object are visible;
detecting the at least one portion of the marker in the real-world image;
registering a virtual world with respect to the real world, on the basis of the detection of the at least one portion of the marker;
placing a three-dimensional virtual object in the registered virtual world, such that the virtual object is substantially overlaid, in the virtual world, on the real object in the real world;
applying a texture on the three-dimensional virtual object,
displaying at least the texture applied to the three-dimensional virtual object, the display being performed from a viewpoint in the virtual world that corresponds to the position of the image acquisition module in the real world; and
displaying the real-world image, the texture applied to the three-dimensional virtual object being displayed in such a manner to be overlaid on the real-world image being displayed,
wherein the marker is a non-repetitive pattern having a high black-and-white contrast ratio with a black intensity difference of at least 70 points.
