      Zhang, Jian. J.; You, L. H. (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      Although the control-point based parametric approach is used most widely in free-form surface modelling, complementary techniques co-exist to meet various specialised requirements. The partial differential equation (PDE) ...

    • Fast Techniques for Mosaic Rendering 

      DiBlasi, G.; Gallo, G.; Petralia, M. (The Eurographics Association, 2005)
      Art often provides valuable hints for technological innovations especially in the field of Image Processing and Computer Graphics. In this paper we survey in an unified framework three methods to transform a raster input ...

    • Fast Texture Synthesis on Arbitrary Meshes 

      Magda, Sebastian; Kriegman, David (The Eurographics Association, 2003)
      While texture synthesis on surfaces has received much attention in computer graphics, the ideal solution that quickly produces high-quality textures with little user intervention has remained elusive. The algorithm presented ...

    • Fast Updates for Least-Squares Rotational Alignment 

      Zhang, Jiayi Eris; Jacobson, Alec; Alexa, Marc (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      Across computer graphics, vision, robotics and simulation, many applications rely on determining the 3D rotation that aligns two objects or sets of points. The standard solution is to use singular value decomposition (SVD), ...

    • Fast Updating of Delaunay Triangulation of Moving Points by Bi-cell Filtering 

      Zhou, Yuanfeng; Sun, Feng; Wang, Wenping; Wang, Jiaye; Zhang, Caiming (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Updating a Delaunay triangulation when data points are slightly moved is the bottleneck of computation time in variational methods for mesh generation and remeshing. Utilizing the connectivity coherence between two consecutive ...

    • Fast Visualisation and Interactive Design of Deterministic Fractals 

      Banisch, Sven; Sbert, Mateu (The Eurographics Association, 2008)
      This paper describes an interactive software tool for the visualisation and the design of artistic fractal images. The software (called AttractOrAnalyst) implements a fast algorithm for the visualisation of basins of ...
