Claim 0:
1. A method comprising:
receiving a mesh model of a three-dimensional (“3D”) object, the mesh model comprising a plurality of polygons that are connected to one another and that collectively form a shape of the 3D object at a first level-of-detail;
receiving a point cloud comprising a plurality of points that are disconnected from one another, that are distributed in a 3D space,_ and that collectively form the shape of the 3D object at a second level-of-detail that is greater than the first level-of-detail, wherein each point of the plurality of points comprises positional elements that define a position of that point in the 3D space;
determining a particular region-of-interest of the 3D object based in part on the positional elements of a set of points from the plurality of points that represent part or all of the particular region-of-interest in the point cloud differing by more than a threshold amount from one another or from positions of a first set of polygons from the plurality of polygons that represent part or all of the particular region-of-interest in the mesh model;
reconstructing the particular region-of-interest in the mesh model by modifying the first set of polygons to a second set of polygons based on the positional elements of two or more of the set of points, wherein the second set of polygons comprises more polygons than the first set of polygons and other regions of the mesh model matching a size of the particular region-of-interest, and wherein polygons of the second set of polygons are smaller in size than polygons of the first set of polygons and other polygons of the plurality of polygons; and
generating a modified mesh model of the 3D object in response to reconstructing the particular region-of-interest, wherein the modified mesh model comprises different sets of the plurality of polygons that represent a plurality of regions of the 3D object other than the particular region-of-interest at the first level-of-detail and the second set of polygons that represent the particular region-of-interest at a third level-of-detail that is greater than the second level-of-detail.
