Abstract
Abstract A method of processing images in images comprising three-dimensional objects, the method comprising a step of mapping a two-dimensional image on a face of a three-dimensional object, a step of interaction between a user and the two-dimensional image mapped on the three-dimensional image, intended to enable a user to displace the whole or part of the two-dimensional image on the face of the three-dimensional object. This method enables the user to map a fixed 2D image or a video image on a face of a 3D object, and to displace the image as he wishes on the face of the object he has selected. If the image is constituted by several parts, for example, the parts of a puzzle, the user can independently displace each part of this image, for example, so as to reconstitute the initial image of the puzzle.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
155 words
A method of processing images in images comprising objects in three dimensions, said method comprising a step of mapping a two-dimensional image on a face of a three-dimensional object, characterized in that the method comprises a step of interaction between a user and the two-dimensional image mapped on the three-dimensional object, said interaction step being intended to enable the user to displace the whole or a part of the two-dimensional image on the face of the three-dimensional object, said interaction step including the sub-steps of: determining the smallest parallelepiped rectangle comprising the three-dimensional object, determining the face of said parallelepiped selected by the user, determining the face and the point of the three-dimensional object, selected by the user from the selected face of the parallelepiped, converting co-ordinates in three dimensions of the selected point of the three-dimensional object into co-ordinates in two dimensions, displacing the selected point of the three-dimensional object in a two-dimensional plane.
Claim 2
Independent Claim
155 words
A method of processing images in images comprising objects in three dimensions, said method comprising a step of mapping a two-dimensional image on a face of a three-dimensional object, characterized in that the method comprises a step of interaction between a user and the two-dimensional image mapped on the three-dimensional object, said interaction step being intended to enable the user to displace the whole or a part of the two-dimensional image on the face of the three-dimensional object, said interaction step including the sub-steps of: determining the smallest parallelepiped rectangle comprising the three-dimensional object, determining the face of said parallelepiped selected by the user, determining the face and the point of the three-dimensional object, selected by the user from the selected face of the parallelepiped, converting co-ordinates in three dimensions of the selected point of the three-dimensional object into co-ordinates in two dimensions, displacing the selected point of the three-dimensional object in a two-dimensional plane.
Claim 3
Dependent Claim
80 words
A method of processing images as claimed in claim 1 , characterized in that the sub-step of converting three-dimensional co-ordinates of the selected point of the three-dimensional object into two-dimensional co-ordinates is intended to determine the two-dimensional co-ordinates from the computation of the weights at which the selected point of the three-dimensional object is the barycenter of the apexes of the selected face of the three-dimensional object by applying the weights thus computed to the apexes of the two-dimensional image.
Claim 4
Dependent Claim
61 words
A method of processing images as claimed in claim 1 , characterized in that said sub-step of determining the face of said parallelepiped selected by the user is intended to determine this face on the basis of an imaginary radius between a given viewing point and a user-selected spot on a screen, allowing the display of images comprising the three-dimensional objects.
Claim 5
Dependent Claim
99 words
A method of processing images as claimed in claim 3 , characterized in that said sub-step of determining the face and the point of the three-dimensional object selected by the user is intended to project faces of the three-dimensional object on the selected face of said parallelepiped, the selected face of the three-dimensional object being that one whose projection comprises the point of intersection between the imaginary radius and the selected face of said parallelepiped, the selected point of the three-dimensional object being the point of intersection between the imaginary radius and the selected face of the three-dimensional object.
Claim 6
Dependent Claim
58 words
A method of processing images as claimed in claim 1 , characterized in that said interaction step is effected by means of a cursor whose displacement is controlled by a mouse, the user clicking on the two-dimensional image to be displaced so as to select said image and displacing the cursor so as to displace the selected image.
Claim 7
Dependent Claim
42 words
A computer program product for a data processing device, the computer program product comprising a set of instructions which, once loaded into the data processing device, cause said device to perform the steps of the method as claimed in claim 1 .
