Converting an unstructured mesh into a more structured model is a fundamental building block in many applications, such as reverse engineering and animation. In spite of many attempts to automate this task there still exists no satisfactory method for practical applications: some methods can convert an unstructured triangle mesh into a structured quadrilateral mesh, but quite often the result does not capture the high-level morphology of the shape, making necessary further processing usually performed at hand by professional users.
In this talk I will target articulated objects, introducing a novel method to convert a digital character represented by a triangle mesh into a well structured quad layout that can be used for subsequent modeling and animation. The quad layouts produced by this method follow the intrinsic objects’ structure; contain few irregular vertices of low degree; can be immediately refined into semi-regular quad meshes and provide a structured domain for UV-mapping and parametrization.
Finally, I will discuss some preliminary ideas on how to extend this method to the volumetric scenario, in order to produce high-quality hexahedral meshes.
