      We propose an efficient method to model paper tearing in the context of interactive modeling. The method uses geometrical information to automatically detect potential starting points of tears. We further introduce a new ...
    • kDet: Parallel Constant Time Collision Detection for Polygonal Objects 

      Weller, René; Debowski, Nicole; Zachmann, Gabriel (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We define a novel geometric predicate and a class of objects that enables us to prove a linear bound on the number of intersecting polygon pairs for colliding 3D objects in that class. Our predicate is relevant both in ...
    • Learning Detail Transfer based on Geometric Features 

      Berkiten, Sema; Halber, Maciej; Solomon, Justin; Ma, Chongyang; Li, Hao; Rusinkiewicz, Szymon (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      The visual richness of computer graphics applications is frequently limited by the difficulty of obtaining high-quality, detailed 3D models. This paper proposes a method for realistically transferring details (specifically, ...
    • Makeup Lamps: Live Augmentation of Human Faces via Projection 

      Bermano, Amit Haim; Billeter, Markus; Iwai, Daisuke; Grundhöfer, Anselm (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We propose the first system for live dynamic augmentation of human faces. Using projector-based illumination, we alter the appearance of human performers during novel performances. The key challenge of live augmentation ...
    • Multi-View Stereo on Consistent Face Topology 

      Fyffe, Graham; Nagano, Koki; Huynh, Loc; Saito, Shunsuke; Busch, Jay; Jones, Andrew; Li, Hao; Debevec, Paul (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We present a multi-view stereo reconstruction technique that directly produces a complete high-fidelity head model with consistent facial mesh topology. While existing techniques decouple shape estimation and facial tracking, ...
    • Multiple Vertex Next Event Estimation for Lighting in dense, forward-scattering Media 

      Weber, Pascal; Hanika, Johannes; Dachsbacher, Carsten (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We present a new technique called Multiple Vertex Next Event Estimation, which outperforms current direct lighting techniques in forward scattering, optically dense media with the Henyey-Greenstein phase function. Instead ...
    • On Realism of Architectural Procedural Models 

      Beneš, Jan; Kelly, Tom; Děchtěrenko, Filip; Křivánek, Jaroslav; Müller, Pascal (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      The goal of procedural modeling is to generate realistic content. The realism of this content is typically assessed by qualitatively evaluating a small number of results, or, less frequently, by conducting a user study. ...
    • Parallel BVH Construction using Progressive Hierarchical Refinement 

      Hendrich, Jakub; Meister, Daniel; Bittner, Jiří (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We propose a novel algorithm for construction of bounding volume hierarchies (BVHs) for multi-core CPU architectures. The algorithm constructs the BVH by a divisive top-down approach using a progressively refined cut of ...
    • Performance-Based Biped Control using a Consumer Depth Camera 

      Lee, Yoonsang; Kwon, Taesoo (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We present a technique for controlling physically simulated characters using user inputs from an off-the-shelf depth camera. Our controller takes a real-time stream of user poses as input, and simulates a stream of target ...
