  • Accelerating Hair Rendering by Learning High-Order Scattered Radiance 

    KT, Aakash; Jarabo, Adrian; Aliaga, Carlos; Chiang, Matt Jen-Yuan; Maury, Olivier; Hery, Christophe; Narayanan, P. J.; Nam, Giljoo (The Eurographics Association and John Wiley & Sons Ltd., 2023)
    Efficiently and accurately rendering hair accounting for multiple scattering is a challenging open problem. Path tracing in hair takes long to converge while other techniques are either too approximate while still being ...

  • A Practical and Hierarchical Yarn-based Shading Model for Cloth 

    Zhu, Junqiu; Montazeri, Zahra; Aubry, Jean-Marie; Yan, Ling-Qi; Weidlich, Andrea (The Eurographics Association and John Wiley & Sons Ltd., 2023)
    Realistic cloth rendering is a longstanding challenge in computer graphics due to the intricate geometry and hierarchical structure of cloth: Fibers form plies which in turn are combined into yarns which then are woven or ...

  • Iridescent Water Droplets Beyond Mie Scattering 

    Xia, Mengqi (Mandy); Walter, Bruce; Marschner, Steve (The Eurographics Association and John Wiley & Sons Ltd., 2023)
    Looking at a cup of hot tea, an observer can see color patterns and granular textures both on the water surface and in the steam. Motivated by this example, we model the appearance of iridescent water droplets. Mie scattering ...

  • LoCoPalettes: Local Control for Palette-based Image Editing 

    Chao, Cheng-Kang Ted; Klein, Jason; Tan, Jianchao; Echevarria, Jose; Gingold, Yotam (The Eurographics Association and John Wiley & Sons Ltd., 2023)
    Palette-based image editing takes advantage of the fact that color palettes are intuitive abstractions of images. They allow users to make global edits to an image by adjusting a small set of colors. Many algorithms have ...

  • Interactive Control over Temporal Consistency while Stylizing Video Streams 

    Shekhar, Sumit; Reimann, Max; Hilscher, Moritz; Semmo, Amir; Döllner, Jürgen; Trapp, Matthias (The Eurographics Association and John Wiley & Sons Ltd., 2023)
    Image stylization has seen significant advancement and widespread interest over the years, leading to the development of a multitude of techniques. Extending these stylization techniques, such as Neural Style Transfer ...

  • PVP: Personalized Video Prior for Editable Dynamic Portraits using StyleGAN 

    Lin, Kai-En; Trevithick, Alex; Cheng, Keli; Sarkis, Michel; Ghafoorian, Mohsen; Bi, Ning; Reitmayr, Gerhard; Ramamoorthi, Ravi (The Eurographics Association and John Wiley & Sons Ltd., 2023)
    Portrait synthesis creates realistic digital avatars which enable users to interact with others in a compelling way. Recent advances in StyleGAN and its extensions have shown promising results in synthesizing photorealistic ...

  • Practical Acquisition of Shape and Plausible Appearance of Reflective and Translucent Objects 

    Lin, Arvin; Lin, Yiming; Ghosh, Abhijeet (The Eurographics Association and John Wiley & Sons Ltd., 2023)
    We present a practical method for acquisition of shape and plausible appearance of reflective and translucent objects for realistic rendering and relighting applications. Such objects are extremely challenging to scan with ...
