    摘要: Embodiments relates to a method for encrypting a 3D object (O) defined at least by a set of first points (pi) and a set first of faces (F), contained in a bounding box (B), the method being executed by an encryption device and comprising: determining (S4) a set of second points (psi) by bijection of the set of first points (pi), and a second set of faces (Fs), determining (S5) an encrypted 3 D object (Os) defined at least by the set of second points (psi) and the second set of faces (Fs), wherein the first points (pi) are associated with respective first indexes (i), the second points (psi) are associated with respective second indexes (sj), and a face is specified by a list of indexes, wherein the encrypted 3D object (Os) is contained in said bounding box (B), the method further comprising: partitioning the bounding box (B) into a set of first sub-boxes (nj), determining a set of second sub-boxes (nsj) by bijection of the set of first sub-boxes (nj), in function of a secret key (k), wherein the position of a second point (psi) is (c) determined in function the position of the corresponding first point (pi), the position of the first sub-box (nj) containing the corresponding first point, and the position of the second sub-box (nsj) corresponding with said first sub-box (nj).

    摘要: A method of digital continuous and simultaneous three-dimensional painting and three-dimensional drawing with steps of providing a digital electronic canvas having at least one display and capable of presenting two pictures for a right eye and a left eye; providing means for continuous changing of a virtual distance between the digital electronic canvas and a painter by digitally changing a horizontal disparity (shifting) between images for the right eye and the left eye on the digital electronic canvas corresponding to instant virtual canvas position; providing at least one multi-axis input control device allowing digital painting or drawing on the digital electronic canvas; painting on the digital electronic canvas for any instant virtual positions of the digital electronic canvas providing simultaneous appearance of a similar stroke on the images for the right eye and the left eye.
