  • Epipolar Methods for Multi-View Sketching . 

    Karpenko, Olga; Hughes, John F.; Raskar, Ramesh (The Eurographics Association, 2004)
    Single view sketch-based modelers like SKETCH and Teddy can be powerful tools, but sometimes their inferences are inadequate: in Teddy, for example, if one draws an animal shape, the centerline of the tail will always lie ...

  • Sketching Garments for Virtual Characters . 

    Turquin, Emmanuel; Cani, Marie-Paule; Hughes, John F. (The Eurographics Association, 2004)
    We present a method for simply and interactively creating basic garments for dressing virtual characters in applications like video games. The user draws an outline of the front or back of the garment, and the system makes ...

  • A Sketch-Based Interface for Collaborative Design . 

    Fan, Zhe; Chi, Ma; Kaufman, Arie; Oliveira, Manuel M. (The Eurographics Association, 2004)
    We present an interface for collaborative conceptual design that combines sketch elements, direct manipulation of 3D objects and non-photorealistic rendering. Such a combination results in a simple and intuitive 2D-sketch-to- ...

  • Constraint Stroke-Based Oversketching for 3D Curves. 

    Fleisch, Timo; Rechel, Florian; Santos, Pedro; Stork, André (The Eurographics Association, 2004)
    In this paper we present an extended approach for stroke oversketching. The stroke oversketching technique changes a curve by redrawing parts of it. Finding the part to replace and smoothing the transition is done ...

  • Relief: A Modeling by Drawing Tool 

    Bourguignon, David; Chaine, Raphaelle; Cani, Marie-Paule; Drettakis, George (The Eurographics Association, 2004)
    This paper presents a modeling system which takes advantage of two-dimensional drawing knowledge to design three-dimensional free-form shapes. A set of mouse or tablet strokes is interpreted by the system as defining both ...

  • Towards 3DModeling using Sketches and Retrieval 

    Fonseca, Manuel J.; Ferreira, Alfredo; Jorge, Joaquim A. (The Eurographics Association, 2004)
    Retrieving 2D and 3D drawings by content is not an easy task. Automatic feature extraction, indexing and matching are some of the problems raised by these approaches. We have developed a generic method to classify, index ...

  • A Two-Stage Approach for Interpreting Line Drawings of Curved Objects 

    Varley, P. A. C.; Takahashi, Y.; Mitani, J.; Suzuki, H. (The Eurographics Association, 2004)
    We describe a two-stage approach for interpreting line drawings of curved objects. In the first stage, the user enters a natu-ral line drawing of a polyhedral template; this is automatically interpreted as the corresponding ...

  • From raw 3D-Sketches to exact CAD product models Concept for an assistant-system 

    Diehl, Holger; Müller, Franz; Lindemann, Udo (The Eurographics Association, 2004)
    As we try to develop new 3D-Sketching devices we come across the problem of how to transfer 3D-Sketches into exact product models to gain an integrated design system. There are some promising approaches for the retrieving ...

  • Spatial Recognition and Grouping of Text and Graphics 

    Shilman, Michael; Viola, Paul (The Eurographics Association, 2004)
    We present a framework for simultaneous grouping and recognition of shapes and symbols in free-form ink diagrams. The approach is completely spatial, that is it does not require any ordering on the strokes. It also does ...

  • On the Evolution of Geometrical Reconstruction as a Core Technology to Sketch-Based Modeling 

    Company, Pedro; Piquer, Ana; Contero, Manuel (The Eurographics Association, 2004)
    In this work, the background and evolution of three-dimensional reconstruction of line drawing over the last thirty years is discussed. A new general taxonomy is proposed to describe and discuss the historical evolution ...

  • Pen Stroke Extraction and Refinement using Learned Models 

    Simhon, Saul; Dudek, Gregory (The Eurographics Association, 2004)
    This paper presents a smart interface that automatically extracts and refines pen strokes from images of hand drawn sketches. The interface allows users to digitize hand-drawn material such sketches of flowcharts, cartoons ...

  • Can Machines Interpret Line Drawings? 

    Varley, P. A. C.; Suzuki, H.; Martin, R. R. (The Eurographics Association, 2004)
    Engineering design would be easier if a computer could interpret initial concept drawings. We outline an approach for automated interpretation of line drawings of polyhedra, and summarise what is already possible, what ...

  • Adaptation of Brensen s Thresholding Algorithm for Sketched Line Drawings 

    Bartolo, Alexandra; Camilleri, Kenneth P.; Farrugia, Philip J.; Borg, Jonathan C. (The Eurographics Association, 2004)
    Image binarisation is one of the first image processing techniques within a sketched line drawing interpretation system. In order to achieve an automated system, it is necessary to have a single algorithmwhich may be used ...

  • Pen-to-mime: A Pen-Based Interface for Interactive Control of A Human Figure 

    Oshita, Masaki (The Eurographics Association, 2004)
    This paper presents a pen-based intuitive interface to control a virtual human figure interactively. Recent commercial pen devices can detect not only the pen positions but also the pressure and tilt of the pen. We utilize ...

  • Cascading Recognizers for Ambiguous Calligraphic Interaction . 

    Pereira, João P.; Branco, Vasco A.; Jorge, Joaquim A.; Silva, Nelson F.; Cardoso, Tiago D.; Ferreira, F. Nunes (The Eurographics Association, 2004)
    Throughout the last decade many approaches have been made to the problem of developing CAD systems that are usable in the early stages of product ideation. Although most of these approaches rely on some kind of drawing ...

  • A Multi-Agent System for the Interpretation of Architectural Sketches 

    Juchmes, Roland; Leclercq, Pierre (The Eurographics Association, 2004)
    Architects widely resort to sketch during their early phase of design, because sketching appears to be the most adapted mean to express and to manipulate creative ideas. In order to assist the designers during this inventive ...
