    • A Bending Model for Nodal Discretizations of Yarn-Level Cloth 

      Pizana, José María; Rodríguez, Alejandro; Cirio, Gabriel; Otaduy, Miguel A. (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      To deploy yarn-level cloth simulations in production environments, it is paramount to design very efficient implementations, which mitigate the cost of the extremely high resolution. To this end, nodal discretizations ...

    • BlenderCAVE: Easy VR Authoring for Multi-Screen Displays 

      Gascón, Jorge; Bayona, José M.; Espadero, José M.; Otaduy, Miguel A. (The Eurographics Association, 2021)
      BlenderCave is a framework for the fast creation of virtual reality applications for multi-screen display systems. It consists of a set of extensions to the open-source Blender Game Engine (BGE), leveraging the scene ...

    • Fast Numerical Coarsening with Local Factorizations 

      He, Zhongyun; Pérez, Jesús; Otaduy, Miguel A. (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      Numerical coarsening methods offer an attractive methodology for fast simulation of objects with high-resolution heterogeneity. However, they rely heavily on preprocessing, and are not suitable when objects undergo dynamic ...

    • High-Order Elasticity Interpolants for Microstructure Simulation 

      Chan-Lock, Antoine; Pérez, Jesús; Otaduy, Miguel A. (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      We propose a novel formulation of elastic materials based on high-order interpolants, which fits accurately complex elastic behaviors, but remains conservative. The proposed high-order interpolants can be regarded as a ...

    • Learning-Based Animation of Clothing for Virtual Try-On 

      Santesteban, Igor; Otaduy, Miguel A.; Casas, Dan (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      This paper presents a learning-based clothing animation method for highly efficient virtual try-on simulation. Given a garment, we preprocess a rich database of physically-based dressed character simulations, for multiple ...

    • Linear-Time Dynamics of Characters with Stiff Joints 

      Hernández, Fernando; Garre, Carlos; Casillas, Rubén; Otaduy, Miguel A. (The Eurographics Association, 2021)
      Characters, like other articulated objects and structures, are typically simulated using articulated dynamics algorithms. There are efficient linear-time algorithms for the simulation of open-chain articulated bodies, but ...

    • Mixing Yarns and Triangles in Cloth Simulation 

      Casafranca, Juan J.; Cirio, Gabriel; Rodríguez, Alejandro; Miguel, Eder; Otaduy, Miguel A. (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      This paper presents a method to combine triangle and yarn models in cloth simulation, and hence leverage their best features. The majority of a garment uses a triangle-based model, which reduces the overall computational ...

    • Modeling and Estimation of Nonlinear Skin Mechanics for Animated Avatars 

      Romero, Cristian; Otaduy, Miguel A.; Casas, Dan; Pérez, Jesús (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Data-driven models of human avatars have shown very accurate representations of static poses with soft-tissue deformations. However they are not yet capable of precisely representing very nonlinear deformations and highly ...

    • Neural Data Exploration with Force Feedback 

      Raya, Laura; Otaduy, Miguel A.; García, Marcos (The Eurographics Association, 2021)
      The behavior of the brain depends to a large extend on its neural structure. Therefore, understanding this neural topology is a high-priority research line for neurobiologists. Due to complexity of the brain's neural ...

    • Parametric Skeletons with Reduced Soft‐Tissue Deformations 

      Tapia, Javier; Romero, Cristian; Pérez, Jesús; Otaduy, Miguel A. (© 2021 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2021)
      We present a method to augment parametric skeletal models with subspace soft‐tissue deformations. We combine the benefits of data‐driven skeletal models, i.e. accurate replication of contact‐free static deformations, with ...

    • Simulation of Dendritic Painting 

      Canabal, José A.; Otaduy, Miguel A.; Kim, Byungmoon; Echevarria, Jose (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      We present a new system for interactive dendritic painting. Dendritic painting is characterized by the unique and intricate branching patterns that grow from the interaction of inks, solvents and medium. Painting sessions ...
