    • Shadow Buttons: Exposing WIMP Functionality While Preserving the Inking Surface in Sketch-Based Interfaces 

      Marinkas, Diane; Zeleznik, Robert C.; Jr., Joseph J. LaViola (The Eurographics Association, 2009)
      We present Shadow Buttons, an approach to placing WIMP interface elements into gestural and sketch-based interfaces. Utilizing the hover state, supported by pen-based devices such as Tablet PCs, we provide users with ...

    • Sketch-Based Interaction and Calligraphic Tags to Create Comics Online 

      Lopes, Ricardo; Cardoso, Tiago; Silva, Nelson; Fonseca, Manuel J. (The Eurographics Association, 2009)
      Over the last years, amateur artists have been using the new Internet technologies to easily produce, share and distribute their comics. However, web applications for this kind of creation are still restricting users by ...

    • A Sketch-based Interface for Photo Pop-up 

      Ventura, J.; DiVerdi, S.; Höllerer, T. (The Eurographics Association, 2009)
      We present sketch-based tools for single-view modeling which allow for quick 3D mark-up of a photograph. With our interface, detailed 3D models can be produced quickly and easily. After establishing the background geometry, ...

    • Sketch-Based Subdivision Models 

      Nasriy, A.; Karam, W. Bou; Samavati, F. (The Eurographics Association, 2009)
      Designing a control mesh (or a polyhedron) for a subdivision model is a tedious task. It involves many difficult decisions such as how to minimize the number of extraordinary vertices, how best to choose their valencies, ...

    • Sketching Subdivision Surfaces 

      Bein, M.; Havemann, S.; Stork, A.; Fellner, Dieter W. (The Eurographics Association, 2009)
      We describe a 3D modeling system that combines subdivision surfaces with sketch-based modeling in order to meet two conflicting goals: ease of use and fine-grained shape control. For the excellent control, low-poly modeling ...

    • Sort, Merge, Repeat: An Algorithm for Effectively Finding Corners in Hand-sketched Strokes 

      Wolin, A.; Paulson, B.; Hammond, T. (The Eurographics Association, 2009)
      Free-sketch recognition systems attempt to recognize freely-drawn sketches without placing stylistic constraints on the users. Such systems often recognize shapes by using geometric primitives that describe the shape's ...

    • Tools for the Efficient Generation of Hand-Drawn Corpora Based on Context-Free Grammars 

      MacLean, Scott; Tausky, David; Labahn, George; Lank, Edward; Marzouk, Mirette (The Eurographics Association, 2009)
      In sketch recognition systems, ground-truth data sets serve to both train and test recognition algorithms. Unfortunately, generating data sets that are sufficiently large and varied is frequently a costly and time-consuming ...

    • Towards Beautification of Freehand Sketches using Suggestions 

      Murugappan, S.; Sellamani, S.; Ramani, K. (The Eurographics Association, 2009)
      Beautification of freehand sketches is integral for building robust sketch understanding systems and sketch-based inter-faces for CAD. Many of the current methods for beautification do not consider some important information ...

    • A Usability Evaluation of AlgoSketch: A Pen-Based Application for Mathematics 

      O'Connell, Theresa; Li, Chuanjun; Miller, Timothy S.; Zeleznik, Robert C.; Jr., Joseph J. LaViola (The Eurographics Association, 2009)
      AlgoSketch is a pen-based system for entering and editing mathematics. It supports interactive computation and early-stage mathematical algorithm design. In its paper-like environment, mathematical expressions can be en- ...

    • Visual Languages and Visual Thinking: Sketch Based Interaction and Modeling 

      Gross, M. D. (The Eurographics Association, 2009)
      Research on sketching with computers dates to the earliest days of modern computing. Recent work in this area, combined with other advances in hardware and software technologies promises, finally, significant impact. The ...

    • VolumeViewer: An Interactive Tool for Fitting Surfaces to Volume Data 

      Sowell, R.; Liu, L.; Ju, T.; Grimm, C.; Abraham, C.; Gokhroo, G.; Low, D. (The Eurographics Association, 2009)
      Recent advances in surface reconstruction algorithms [BM07,LBD08] allow surfaces to be built from contours lying on non-parallel planes. Such algorithms allow users to construct surfaces of similar quality more efficiently ...
