      Casu, Andrea; Spano, Lucio Davide; Sorrentino, Fabio; Scateni, Riccardo (The Eurographics Association, 2015)
      The recent development in consumer hardware lowers the cost barrier for adopting immersive Virtual Reality (VR) solutions, which could be an option for classroom use in the near future. In this paper, we introduce RiftArt, ...

    • Rig-Space Motion Retargeting 

      Hu, Lin-Chuan; Chang, Ming-Hsu; Chuang, Yung-Yu (The Eurographics Association, 2016)
      This paper presents a framework for transferring rig parameters from a source animation to a target model, allowing artists to further refine and adjust the animation. Most previous methods only transfer animations to ...

    • A Rigging-Skinning Scheme to Control Fluid Simulation 

      Lu, Jia-Ming; Chen, Xiao-Song; Yan, Xiao; Li, Chen-Feng; Lin, Ming; Hu, Shi-Min (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Inspired by skeletal animation, a novel rigging-skinning flow control scheme is proposed to animate fluids intuitively and efficiently. The new animation pipeline creates fluid animation via two steps: fluid rigging and ...

    • Rigid Body Contact Problems using Proximal Operators 

      Erleben, Kenny (ACM, 2017)
      Iterative methods are popular for solving contact force problems in rigid body dynamics. They are loved for their robustness and surrounded by mystery as to whether they converge or not. We provide a mathematical foundation ...

    • Rigid Body Joints in Real-Time Unified Particle Physics 

      Lovrovic, Bojan; Mihajlovic, Zeljka (The Eurographics Association, 2018)
      In this paper, we propose a physically-based method for a rigid body joint simulation. The proposed solution is based on the unified particle physics engine, a simulator that uses only particles for all the dynamic bodies. ...

    • Rigid Registration of Point Clouds Based on Partial Optimal Transport 

      Qin, Hongxing; Zhang, Yucheng; Liu, Zhentao; Chen, Baoquan (© 2022 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd., 2022)
      For rigid point cloud data registration, algorithms based on soft correspondences are more robust than the traditional ICP method and its variants. However, point clouds with severe outliers and missing data may lead to ...

    • A Rigid Transform Basis for Animation Compression and Level of Detail 

      Collins, G.; Hilton, A. (The Eurographics Association, 2005)
      We present a scheme for achieving level of detail and compression for animation sequences with known constant connectivity. We suggest compression is useful to automatically create low levels of detail in animations which ...
