"Medallions" is comprised of a series of wall plaques featuring ornate shapes. In this work, each medallion was procedurally generated, and 3D-printed. This project is an attempt at translation from traditional ornamentation to a modern algorithmic art by using a combination of a procedural approach in Computer Generated Imagery (CGI) and the rapidly expanding field of 3D-printing technology. As an element of the medallions, we used 2D metaballs, which are a kind of modeling method in CGI. A drawing algorithm of the metaballs was modi ed and optimized to generate complicated ornate patterns. Also, regular-polygonal shapes were used for the process of density calculation of each metaball. However, a generated 2D pattern cannot be converted into a 3D model directly because there is an inconsistency that lines with convex information overlap each other in the intersection points on the 2D pattern. To solve the issue, we used an algorithm that an accurate peak height level is calculated at each pixel; the algorithm enables us to generate lines without overlaps. In this way, generated patterns were converted into 3D models, and then the models were 3D-printed nally. The nished artworks were displayed at several art exhibitions, and gained a certain reputation.
