Usai F., Livesu M., Puppo E., Tarini M., Scateni R. Extraction of the quad layout of a triangle mesh guided by its curve-skeleton. In: ACM Transactions on Graphics (TOG), vol. 35 (1) article n. 6. ACM, 2015.
Starting from the triangle mesh of a digital shape, mainly an articulated object, we produce a coarse quad layout that can be used in character modeling and animation. Our quad layout follows the intrinsic object structure described by its curve skeleton; it contains few irregular vertices of low degree; it can be immediately refined into a semi-regular quad mesh; it provides a structured domain for UV-mapping and parametrization. Our method is fast, one-click and it does not require any parameter setting. The user can steer and refine the process through simple interactive tools during the construction of the quad layout.
