Dr. KID is an algorithm that uses isometric decomposition for the physicalization of potato-shaped organic models in a puzzle fashion. The algorithm begins with creating a simple, regular triangular surface mesh of organic shapes, followed by iterative k-means clustering and remeshing. For clustering, we need similarity between triangles (segments)...

... normal, on the other hand, yields similar sizes for both layers without regard to curvature. Figure 6 shows the thickened triangle patches using different approaches (see Figure 6a and 6b) on a full surface. In the case of face normals (perpendicular extrusion), for each triangle patch, the inner and outer layers are the same; therefore in modeling there is some free space between them. ...

... handle this issue, we find mean curvature for all parts in each class to finalize the positions of the new vertices (v 1 , v 2 , v 3 ). Subdivision smoothing gives even better results (see Figure 6c). The inner and outer triangle surface patches are linked with quad strips linking the corresponding vertices. ...
