dc.description.abstractScales are a visually striking feature that grows on many animals. These small, rigid plates embedded in the skin form an integral part of our description of ?sh and reptiles, some plants, and many extinct animals. Scales exist in many shapes and sizes, and serve as protection, camou?age, and plumage for animals. The variety of scales and the animals they grow from pose an interesting problem in the ?eld of Computer Graphics. This dissertation presents a method for generating scales and scale-like structures on a polygonal mesh through surface replacement. A triangular mesh was covered with scales and one or more proxy-models were used as the scales shape. A user began scale generation by drawing a lateral line on the model to control the distribution and orientation of scales on the surface. Next, a vector ?eld was created over the surface to control an anisotropic Voronoi tessellation, which represents the region occupied by each scale. Then these regions were replaced by cutting the proxy model to match the boundary of the Voronoi region and deform the cut model onto the surface. The ?nal result is a fully connected 2-manifold that is suitable for subsequent post-processing applications, like surface subdivision.
