Otaduy, "Natural Tactile Interaction with Virtual Clay," 2021 IEEE World Haptics Conference (WHC), 2021, pp. 403-408, doi: 10.1109/WHC49131.2021.9517171.http://hdl.handle.net/10115/18252Despite many past efforts to develop haptic experiences of virtual clay modeling, natural interaction with virtual clay remains a hard challenge. In this work, we propose a computational solution for the interactive simulation of clay-like materials with unprecedented realism, coupled with free-air tactile rendering that provides a natural tangible experience. Our solution includes a novel particle-based model of viscoplasticity for efficient interactive simulation, and an optimization-based ultrasound rendering algorithm that takes as input the interaction forces between a virtual hand model and the clay-like material. We demonstrate the effectiveness of our method through expressive creative experiences.engAtribución-NoComercial-CompartirIgual 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-sa/4.0/Informáticainfo:eu-repo/semantics/preprint10.1109/WHC49131.2021.9517171.info:eu-repo/semantics/openAccess1203.17 Informática
