  Visually seamless grafting of volumetric data. In some implementations, a method includes obtaining volumetric data that represents a first volume including one or more three-dimensional objects. Planar slices of the first volume are determined and for each planar slice, a result region and an outer region are determined, the outer region located between the result region and an edge of the planar slice. A target region is determined within the result region and adjacent to an edge of the result region. The result region is modified by updating source voxels in the target region based on corresponding continuity voxels in the outer region, and the updating is weighted based on a distance of each source voxel from an associated edge of the result region. The modified result regions are grafted to a second volume at the edge of the result regions to provide a grafted volume.
