    • Bubble hierarchies 

      Hlawatsch, Marcel; Burch, Michael; Weiskopf, Daniel (ACM, 2014)
      We introduce bubble hierarchies as an approach to generating algorithmic art from random hierarchies. The technique is based on repeatedly drawing color-coded circles to illustrate parent--child relationships. The algorithm ...
    • Non-realistic 3D object stylization 

      Kratt, Julian; Eisenkeil, Ferdinand; Pirk, Sören; Sharf, Andrei; Deussen, Oliver (ACM, 2014)
      In this paper we introduce the novel paradigm of non-realistic 3D stylization, where the expressiveness of a given 3D model is manifested in the 3D shape itself, rather than only in its rendering. We analyze the input model ...
    • Spirograph inspired visualization of ecological networks 

      Etemad, Katayoon; Carpendale, Sheelagh; Samavati, Faramarz (ACM, 2014)
      Ecological networks are directed weighted graphs for representing direct and indirect relationships between species in ecosystems. These complex cyclic networks play an important role in understanding an ecosystem's dynamics. ...
    • Image filtering for interactive level-of-abstraction visualization of 3D scenes 

      Semmo, Amir; Döllner, Jürgen (ACM, 2014)
      Texture mapping is a key technology in computer graphics for visual design of rendered 3D scenes. An effective information transfer of surface properties, encoded by textures, however, depends significantly on how important ...
    • A study of image colourfulness 

      Amati, Cristina; Mitra, Niloy J.; Weyrich, Tim (ACM, 2014)
      Colourfulness is often thought of as a mere measure of quantity of colour, but user studies suggest that there are more factors influencing the perception of colourfulness. Boosting and enhancing colours are operations ...
    • Dynamic sketching: simulating the process of observational drawing 

      Liu, Jingbo; Fu, Hongbo; Tai, Chiew-Lan (ACM, 2014)
      The creation process of a drawing provides a vivid visual progression, allowing the audience to better comprehend the drawing. It also enables numerous stroke-based rendering techniques. In this work we tackle the problem ...
    • Line-based rendering with truchet-like tiles 

      Ahmed, Abdalla G. M. (ACM, 2014)
      We explore the use of Truchet-like tiles (tiles with half area shaded) for single-tone (monochrome) line-based rendering of maps. We borrow concepts from information theory to develop some qualitative and quantitative ...
    • Computational rim illumination with aerial robots 

      Srikanth, Manohar; Bala, Kavita; Durand, Frédo (ACM, 2014)
      Lighting plays a major role in photography. Professional photographers use elaborate installations to light their subjects and achieve sophisticated styles. However, lighting moving subjects performing dynamic tasks presents ...
    • Collaborative filtering of color aesthetics 

      O'Donovan, Peter; Agarwala, Aseem; Hertzmann, Aaron (ACM, 2014)
      This paper investigates individual variation in aesthetic preferences, and learns models for predicting the preferences of individual users. Preferences for color aesthetics are learned using a collaborative filtering ...
    • The monumental geometry of E Pluribus Unum 

      Kaplan, Craig S.; Jordan, Chris (ACM, 2014)
      We describe the conception and construction of E Pluribus Unum, a large-scale artwork that combines text and geometry to depict over a million names of global organizations dedicated to social and environmental causes. The ...
    • What does water look like? 

      Kryven, Marta; Cowan, William (ACM, 2014)
      What makes images of water look like water? We conducted four psychophysical experiments to isolate perceptual qualities that make water easy to recognize. Water recognition is facilitated by colour and by three patterns ...
    • Frayed cell diagrams 

      Burch, Michael; Vehlow, Corinna; Weiskopf, Daniel (ACM, 2014)
      Tesselation-based or area-based visual representations are common to many artistic or visualization applications. For example, Voronoi art uses a space-filling tessellation of the image by Voronoi cells. We present frayed ...
