      HAGI is an object-oriented graphics system developed on top of the X window system. In addition to providing facilities that structured graphics systems such as GKS usually have, HAGI supports a high- level graphics paradigm ...
    • Hair Interpolation for Portrait Morphing 

      Weng, Yanlin; Wang, Lvdi; Li, Xiao; Chai, Menglei; Zhou, Kun (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      In this paper we study the problem of hair interpolation: given two 3D hair models, we want to generate a sequence of intermediate hair models that transform from one input to another both smoothly and aesthetically pleasing. ...
    • Hair Modeling and Simulation by Style 

      Jung, Seunghwan; Lee, Sung-Hee (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      As the deformation behaviors of hair strands vary greatly depending on the hairstyle, the computational cost and accuracy of hair movement simulations can be significantly improved by applying simulation methods specific ...
    • Hair, Cloth and Soft Tissues: The Influence of Mechanical Properties on the Real-Time Dynamics of Deformable Objects 

      Magnenat-Thalmann, Nadia; Bonanni, Ugo; Volino, P.; Assassi, L. (The Eurographics Association, 2009)
      In spite of the impressive advancements achieved during the last years in the domain of interactive physically based simulation, the real-time animation of complex deformable objects still represents a challenge. In order ...
    • HairControl: A Tracking Solution for Directable Hair Simulation 

      Milliez, Antoine; Sumner, Robert W.; Gross, Markus; Thomaszewski, Bernhard (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      We present a method for adding artistic control to physics-based hair simulation. Taking as input an animation of a coarse set of guide hairs, we constrain a subsequent higher-resolution simulation of detail hairs to follow ...
    • Hairy Slices II: Depth Cues for Visualizing 3D Streamlines Through Cutting Planes 

      Stevens, Andrew H.; Ware, Colin; Butkiewicz, Thomas; Rogers, David; Abram, Greg (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Visualizing 3D vector fields is challenging because of occlusion problems and the difficulty of providing depth cues that adequately support the perception of direction of flow lines in 3D space. One of the depth cues that ...
    • A Halfedge Refinement Rule for Parallel Catmull-Clark Subdivision 

      Dupuy, Jonathan; Vanhoey, Kenneth (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      We show that Catmull-Clark subdivision induces an invariant one-to-four refinement rule for halfedges that reduces to simple algebraic expressions. This has two important consequences. First, it allows to refine the halfedges ...
    • Halftone Pattern: A New Steganographic Approach 

      Cruz, Leandro; Patrão, Bruno; Gonçalves, Nuno (The Eurographics Association, 2018)
      In general, an image is worth a thousand words, but sometimes, words are the most efficient tool to communicate some information. Thereupon, in this work, we will present an approach for combining the visual appeal of ...
    • Half‐body Portrait Relighting with Overcomplete Lighting Representation 

      Song, Guoxian; Cham, Tat‐Jen; Cai, Jianfei; Zheng, Jianmin (© 2021 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2021)
      We present a neural‐based model for relighting a half‐body portrait image by simply referring to another portrait image with the desired lighting condition. Rather than following classical inverse rendering methodology ...
    • Hallucinating Stereoscopy from a Single Image 

      Zeng, Qiong; Chen, Wenzheng; Wang, Huan; Tu, Changhe; Cohen-Or, Daniel; Lischinski, Dani; Chen, Baoquan (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We introduce a novel method for enabling stereoscopic viewing of a scene from a single pre-segmented image. Rather than attempting full 3D reconstruction or accurate depth map recovery, we hallucinate a rough approximation ...
    • HaloDot: Visualization of the Relevance of Off-Screen Objects 

      Gonçalves, Tiago; Afonso, Ana Paula; Carmo, Maria Beatriz; Pombinho, Paulo (The Eurographics Association, 2021)
      The increasing usage of maps on mobile devices reinforce the need to solve some visualization and usability issues that constraint the user's interaction with information visualization applications. When exploring map ...
