    • Magnetic Curves: Curvature-Controlled Aesthetic Curves Using Magnetic Fields 

      Xu, Ling; Mould, David (The Eurographics Association, 2009)
      We describe 'magnetic curves', a particle-tracing method that creates curves with constantly changing curvature. It is well known that charged particles in a constant magnetic field trace out circular or helical trajectories. ...
    • Learning about Shadows from Artists 

      Fourquet, Elodie (The Eurographics Association, 2010)
      Renaissance artists discovered methods for imaging realistic depth on a two dimensional surface by re-inventing linear perspective. In solving the problem of depth depiction, they observed how shadows project and volumes ...
    • Toward Auvers Period: Evolution of van Gogh's Style 

      Rigau, Jaume; Feixas, Miquel; Sbert, Mateu; Wallraven, Christian (The Eurographics Association, 2010)
      In this paper, we analyze the evolution of van Gogh's style toward the Auvers final period using informational measures. We will try to answer the following questions: Was van Gogh exploring new ways toward changing his ...
    • Discretization of 3D Models Using Voxel Elements of Different Shapes 

      Cavagnino, Davide; Gribaudo, Marco (The Eurographics Association, 2010)
      This paper presents a voxelization algorithm that uses elements of various shapes that are not larger than a single voxel. Elements are chosen from a palette in order to minimize the deviation from the actual object according ...
    • Procedural Generation of Surface Detail for Science Fiction Spaceships 

      Kinnear, Kate; Kaplan, Craig S. (The Eurographics Association, 2010)
      Procedural modelling can be used to generate digital content such as 3D digital models programmatically. In computer graphics, Procedural modelling has focused primarily on natural scenery and cityscapes. This paper considers ...
    • Subdivision Beyond Smoothness 

      Hansmeyer, Michael (The Eurographics Association, 2010)
      This paper examines the role that subdivision processes can have in the production of form. It explores how subdivision processes can generate complex geometries from very simple input meshes. In a first step, this paper ...
    • Brush Stroke Ordering Techniques for Painterly Rendering 

      Northam, Lesley; Istead, Joe; Kaplan, Craig S. (The Eurographics Association, 2010)
      Painterly rendering algorithms often mimic classical hand-painting techniques to automatically generate stylized paintings from input images. These algorithms use a combination of techniques to express a variety of styles ...
    • Stroke Matching for Paint Dances 

      Colton, Simon (The Eurographics Association, 2010)
      We have implemented a non-photorealistic rendering system which simulates the placement of paint/pencil/pastel strokes to produce representational artworks from digital images. The system is able to record an image of each ...
    • Interactive Volume Illustration Using Intensity Filtering 

      Ruiz, Marc; Boada, Imma; Feixas, Miquel; Sbert, Mateu (The Eurographics Association, 2010)
      We propose a simple and interactive technique for volume illustration by using the difference between the original intensity values and a low-pass filtered copy. This difference, known as unsharped mask, provides us with ...
    • Recursive Scene Graphs for Art and Design 

      Wyvill, Brian; Dodgson, Neil A. (The Eurographics Association, 2010)
      Conventional scene graphs use directed acyclic graphs; conventional iterated function systems use infinitely recursive definitions. We investigate scene graphs with recursive cycles for defining graphical scenes. This ...
    • Line Drawings vs. Curvature Shading:Scientific Illustration of Range Scanned Artefacts 

      Hörr, Christian; Brunnett, Guido; Vix, Christian (The Eurographics Association, 2010)
      For scientific archaeological illustrations, pen-and-ink drawings are traditionally the most prevalent type. Over the years, drawing styles have substantially changed several times and even today there is basically no ...
    • A Robust and Universal Gradient Domain Imaging Solver Using Gradient Variables and Locally Varying Metrics 

      Neumann, László; Hegedüs, Ramón (The Eurographics Association, 2010)
      Gradient Domain Imaging (GDI) has gained a high importance and provoked numerous powerful applications over the last decade. It employs a workflow of creating an inconsistent gradient field (GF) from one or more images ...
    • Pannini: A New Projection for RenderingWide Angle Perspective Images 

      Sharpless, Thomas K.; Postle, Bruno; German, Daniel M. (The Eurographics Association, 2010)
      The widely used rectilinear perspective projection cannot render realistic looking flat views with fields of view much wider than 70°. Yet 18th century artists known as 'view painters' depicted wider architectural ...
    • Suggestive Hatching 

      Singh, Mayank; Schaefer, Scott (The Eurographics Association, 2010)
      We present a method for drawing lines on an object that depict both the shape and shading of the object. To do so, we construct a gradient field of the diffuse intensity of the surface to guide a set of adaptively spaced ...
    • Realtime Aesthetic Image Retargeting 

      Liu, Ligang; Jin, Yong; Wu, Qingbiao (The Eurographics Association, 2010)
      Humans have always sought to achieve aesthetics in art. In this paper, we present a novel approach for retargeting images to different aspect ratios while improving the composition aesthetics of the results. A simpler ...
