      In example‐based inverse linear blend skinning (LBS), a collection of poses (e.g. animation frames) are given, and the goal is finding skinning weights and transformation matrices that closely reproduce the input. These ...

    • Real‐Time Deformation with Coupled Cages and Skeletons 

      Corda, F.; Thiery, J. M.; Livesu, M.; Puppo, E.; Boubekeur, T.; Scateni, R. (© 2020 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2020)
      Skeleton‐based and cage‐based deformation techniques represent the two most popular approaches to control real‐time deformations of digital shapes and are, to a vast extent, complementary to one another. Despite their ...

    • Exploring the Effects of Aggregation Choices on Untrained Visualization Users' Generalizations From Data
