    We propose a faster method for surface haptic rendering using image-based Hybrid Rugosity Mesostructures (HRMs), paired maps with per-face height eld displacements and normalmaps, which are layered on top of a much decimated ...

    The present document exposes a different approach for haptic rendering, defined as the simulation of force interactions to reproduce the sensation of surface relief in dense models. Current research shows open issues in ...
  • Hybrid Rugosity Mesostructures (HRMs) for fast and accurate rendering of fine haptic detail 

    Theoktisto, Víctor; Fairén González, Marta; Navazo Álvaro, Isabel (Centro Latinoamericano de Estudios en Informática, 2010)
    Article
    Accés obert
    The haptic rendering of surface mesostructure (fine relief features) in dense triangle meshes requires special structures, equipment, and high sampling rates for detailed perception of rugged models. Low cost approaches ...
  • Rendering detailed haptic textures
