    • Fast Planar Harmonic Deformations with Alternating Tangential Projections 

      Hefetz, Eden Fedida; Chien, Edward; Weber, Ofir (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We present a planar harmonic cage-based deformation method with local injectivity and bounded distortion guarantees, that is significantly faster than state-of-the-art methods with similar guarantees, and allows for real-time ...

    • GWCNN: A Metric Alignment Layer for Deep Shape Analysis 

      Ezuz, Danielle; Solomon, Justin; Kim, Vladimir G.; Ben-Chen, Mirela (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Deep neural networks provide a promising tool for incorporating semantic information in geometry processing applications. Unlike image and video processing, however, geometry processing requires handling unstructured ...

    • Modeling and Exploring Co-variations in the Geometry and Configuration of Man-made 3D Shape Families 

      Laga, Hamid; Tabia, Hedi (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We introduce co-variation analysis as a tool for modeling the way part geometries and configurations co-vary across a family of man-made 3D shapes. While man-made 3D objects exhibit large geometric and structural variations, ...

    • A Parallel Approach to Compression and Decompression of Triangle Meshes using the GPU 

      Jakob, Johannes; Buchenau, Christoph; Guthe, Michael (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Most state-of-the-art compression algorithms use complex connectivity traversal and prediction schemes, which are not efficient enough for online compression of large meshes. In this paper we propose a scalable massively ...
