    • A Generalized Cubemap for Encoding 360° VR Videos using Polynomial Approximation 

      Xiao, Jianye; Tang, Jingtao; Zhang, Xinyu (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      360° VR videos provide users with an immersive visual experience. To encode 360° VR videos, spherical pixels must be mapped onto a two-dimensional domain to take advantage of the existing video encoding and storage standards. ...

      In this paper, we introduce a real-time algorithm to render the rich visual effects of general non-height-field geometric details, known as mesostructure. Our method is based on a five-dimensional generalized displacement ...

    • Generalized Distance Transforms and Skeletons in Graphics Hardware 

      Strzodka, R.; Telea, A. (The Eurographics Association, 2004)
      We present a framework for computing generalized distance transforms and skeletons of two-dimensional objects using graphics hardware. Our method is based on the concept of footprint splatting. Combining different splats ...

    • Generalized Helicoids for Modeling Hair Geometry 

      Piuze, Emmanuel; Kry, Paul G.; Siddiqi, Kaleem (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      In computer graphics, modeling the geometry of hair and hair-like patterns such as grass and fur remains a significant challenge. Hair strands can exist in an extensive variety of arrangements and the choice of an appropriate ...

    • Generalized K-means for Metric Space Clustering Using PageRank 

      Hajij, Mustafa; Said, Eyad; Todd, Robert (The Eurographics Association, 2020)
      We utilize the PageRank vector to generalize the k-means clustering algorithm to directed and undirected graphs. We demonstrate that PageRank and other centrality measures can be used in our setting to robustly compute ...

    • Generalized Light Portals 

      Ogaki, Shinji (ACM, 2020)
      Light portals are useful for accelerating the convergence of Monte Carlo path tracing when rendering interiors. However, they are generally limited to flat polygonal shapes. In this paper, we introduce a new concept that ...

    • Generalized Matryoshka: Computational Design of Nesting Objects 

      Jacobson, Alec (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      This paper generalizes the self-similar nesting of Matryoshka dolls (''Russian nesting dolls'') to arbitrary solid objects. We introduce the problem of finding the largest scale replica of an object that nests inside itself. ...

    • Generalized Model-Based Human Motion Recognition with Body Partition Index Maps 

      Deng, Liqun; Leung, Howard; Gu, Naijie; Yang, Yang (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Content-based human motion analysis has captured extensive concerns of researchers from the domains of computer animation, human-machine interaction, entertainment, etc. However, it is a non-trivial task due to the spatial ...

    • A Generalized Proceduralization Framework for Urban Models with Applications in Procedural Modeling, Synthesis, and Reconstruction 

      Demir, Ilke (ProQuest Dissertations Publishing, 2017)
      The technological developments in the last century have carried us from a few pixels per screen to infinite worlds. Consecutively, recent bottleneck in graphics industry has been changing from the “means” to the “objects”, ...
