  • Shape Modeling with Sketched Feature Lines in Immersive 3D Environments 

    Perkunder, Helen; Israel, Johann Habakuk; Alexa, Marc (The Eurographics Association, 2010)
    In this paper we address the question whether automatic shape creation using sketched strokes as input in an immersive 3D environment supports the sketching process in early phases of product design. To investigate this ...
  • Investigating the Learnability of Immersive Free-Hand Sketching 

    Wiese, Eva; Israel, Johann Habakuk; Meyer, Achim; Bongartz, Sara (The Eurographics Association, 2010)
    Immersive modeling systems which allow for sketching and constructing three-dimensional product models receive growing interest from both academic research and industry [DBWB*00; FASM02; IWMS09; KAMD*08; KAML*01]. The ...
  • Sketch-Based Modeling of Vascular Systems: a First Step Towards Interactive Teaching of Anatomy 

    Pihuit, Adeline; Cani, Marie-Paule; Palombi, Olivier (The Eurographics Association, 2010)
    We present a sketch-based modeling system, inspired from anatomical drawing, which constructs plausible 3D models of branching vessels from a single sketch. The input drawing typically includes non-flat silhouettes and ...
  • Inkus: A Freehand Method of Creating Business Process Models 

    Mangano, Nicolas; Sukaviriya, Noi (The Eurographics Association, 2010)
    Business process modeling has become an industry wide practice for business transformation consulting. Tools that support business process modeling are designed for experienced users to draw a process with precision and ...
  • A Sketching Interface for Sitting-Pose Design 

    Lin, Juncong; Igarashi, Takeo; Mitani, Jun; Saul, Greg (The Eurographics Association, 2010)
    We present a sketch interface for interactively placing a 3D human character in a sitting position on a chair. The user first sketches the target pose as a 2D stick figure. The user can specify whether a joint will be ...
  • Sketch-Based Recognition System for General Articulated Skeletal Figures 

    Zamora, Shane; Sherwood, Timothy (The Eurographics Association, 2010)
    We present a new recognition system for detecting general articulated skeletal figures in sketch-based applications. We abstract drawing style from recognition by defining figures using two data models: templates and figure ...
  • A Pen-Based Tool for Visualizing Vector Mathematics 

    Bott, Jared N.; Jr., Joseph J. LaViola (The Eurographics Association, 2010)
    We present VectorPad, a novel, pen-based application for three-dimensional vector mathematics visualization. VectorPad allows users to define vectors and perform mathematical operations on them through the recognition of ...
  • Exploring Usability and Learnability of Mode Inferencing in Pen/Tablet Interfaces 

    Negulescu, Matei; Ruiz, Jaime; Lank, Edward (The Eurographics Association, 2010)
    The inferred mode protocol uses contextual reasoning and local mediators to eliminate the need to access specific modes to perform draw, select, move and delete operations in a sketch interface. In this paper, we describe ...
  • The Power of Automatic Feature Selection: Rubine on Steroids 

    Blagojevic, Rachel; Chang, Samuel Hsiao-Heng; Plimmer, Beryl (The Eurographics Association, 2010)
    Digital ink features drive recognition engines. Intuitively, we understand that particular features are of more value for some problems than others. Likewise, inclusion of poor features may be detrimental to recognition ...
  • Rata.SSR: Data Mining for Pertinent Stroke Recognizers 

    Chang, Samuel Hsiao-Heng; Plimmer, Beryl; Blagojevic, Rachel (The Eurographics Association, 2010)
    While many approaches to digital ink recognition have been proposed, most lack flexibility and adaptability to provide acceptable recognition rates across a variety of problem spaces. Time and expert knowledge are required ...
  • Feature Extraction and Classifier Combination for Image-based Sketch Recognition 

    Tumen, R. Sinan; Acer, M. Emre; Sezgin, T. Metin (The Eurographics Association, 2010)
    Image-based approaches to sketch recognition typically cast sketch recognition as a machine learning problem. In systems that adopt image-based recognition, the collected ink is generally fed through a standard three stage ...
  • Drawing with the Flow: A Sketch-Based Interface for Illustrative Visualization of 2D Vector Fields 

    Schroeder, David; Coffey, Dane; Keefe, Dan (The Eurographics Association, 2010)
    This paper presents Drawing with the Flow, a sketch-based interface for illustrating 2D vector fields. Drawing with the Flow explores the problem of making scientific visualization tools accessible to artists and illustrators, ...
  • Computing Confidence Values for Geometric Constraints for use in Sketch Recognition 

    Johnston, Joshua; Hammond, Tracy (The Eurographics Association, 2010)
    Geometric constraints are used by many sketch recognition systems to perform high-level assembly of components of a sketch into semantic structures. However, with a few notable exceptions, most of the current recognition ...
  • Exploring Frame Gestures for Fluid Freehand Sketching 

    Nijboer, Menno; Gerl, Moritz; Isenberg, Tobias (The Eurographics Association, 2010)
    In this paper, we explore a minimalistic, gesture-based interface for fluid freehand concept sketching with vector graphics. Our approach leverages the advantages of both the GUI and gestural interface paradigms. We describe ...
  • Assisted Multitouch Image-Based Reconstruction 

    Bauer, Frank; Stamminger, Marc (The Eurographics Association, 2010)

  • Folding Avoidance in Skeletal Strokes 

    Asente, Paul J. (The Eurographics Association, 2010)
    Skeletal strokes is a method for mapping vector artwork defined along a straight path onto an arbitrary destination path. It is commonly used to give sketches a hand-drawn look, by mapping a scanned natural-medium stroke ...
  • Modeling 2.5D Plants from Ink Paintings 

    Amati, Cristina; Brostow, Gabriel J. (The Eurographics Association, 2010)
    Chinese ink painting, known as sumi-e, is a traditional art form based on careful placement of expressive brush strokes. To extend such brush strokes from their paper form, we propose a system that can digitize and transform ...
