Claim Text:
1. A method for modelling a scene from a plurality of maps representative of depth, each map representative of depth being associated with a view of the scene according to a viewpoint, said method comprising: generating, for each map representative of depth of said plurality, a surface representative of said map representative of depth in world space; determining a volume bounding the surfaces generated in said world space, said bounding volume being discretized into a plurality of voxels, associating an attribute representative of transparency with the voxels of the bounding volume; changing a value of the attribute representative of transparency to a transparent state for the voxels of the bounding volume not belonging to view cones formed from each viewpoint associated with said surfaces; associating an attribute representative of transparency with the voxels of the bounding volume; generating, for each surface, a plurality of rays originating from a viewpoint associated with said each surface and having as end point an intersection with said each surface; running through said plurality of generated rays, and changing the value of the attribute representative of transparency for the voxels of the bounding volume having an intersection with one of the generated rays; and generating data representative of a resulting surface according to the attributes representative of transparency associated with said voxels.
