  • Applying Scenarios in User-Centred Design to Develop a Sketching Interface for Human Modelling and Animation 

    Mao, Chen; Qin, Seng Feng; Wright, David K.; Peng, Jun (The Eurographics Association, 2006)
    This paper presents our user and usability studies for applying scenarios in user-centred design to develop a sketching interface for virtual human modelling and animation. In this approach, we utilise the User Centred ...
  • An Initial Evaluation of a Pen-Based Tool for Creating Dynamic Mathematical Illustrations 

    LaViola Jr., Joseph J. (The Eurographics Association, 2006)
    MathPad2is a pen-based application prototype for creating mathematical sketches. Using a modeless gestural interface, it lets users make dynamic illustrations by associating handwritten mathematics with free-form drawings ...
  • Sketch-based Volumetric Seeded Region Growing 

    Chen, Hung-Li Jason; Samavati, Faramarz F.; Sousa, Mario Costa; Mitchell, J. Ross (The Eurographics Association, 2006)
    Interactive volume segmentation is an essential and important step in medical image processing. Conventional interactive methods typically demand significant amounts of time and do not lend to a natural interaction scheme ...
  • A Study of Usability of Sketching Tools Aimed at Supporting Prescriptive Sketches 

    Company, Pedro; Contero, Manuel; Naya, F.; Aleixos, N. (The Eurographics Association, 2006)
    Prescriptive sketches are usually drawn, after conceptual design is over, to prepare the creation of digital 3D models. Designers and draftsmen use them as screenplays that guide the creation of the final 3D model. ...
  • Sketch-based 3D Engineering Part Class Browsing and Retrieval 

    Hou, Suyu; Ramani, Karthik (The Eurographics Association, 2006)
    We present a two-tier sketch-based engineering part retrieval system enhanced with classifier combination. Given a free-hand user sketch, we propose to use an ensemble of classifiers to estimate the likelihood of the sketch ...
  • Living Ink: Implementation of a Prototype Sketching Language for Real Time Authoring of Animated Line Drawings 

    Rogers, Bill (The Eurographics Association, 2006)
    Sketching with pen on paper is often used as a way of augmenting spoken descriptions: to help explain how some mechanical device works; to show the flow of information in an organisation, to show the action in a story, and ...
  • A Sketching Interface for 3D Modeling of Polyhedrons 

    Ku, Day Chyi; Qin, S. F.; Wright, D. K. (The Eurographics Association, 2006)
    We present an intuitive and interactive freehand sketching interface for 3D polyhedrons reconstruction. The interface mimics sketching with pencil on paper and takes freehand sketches as input directly. The sketching ...
  • Sketching Reaction-Diffusion Texture 

    Phan, Ly; Grimm, Cindy (The Eurographics Association, 2006)
    In this work, we present an interactive interface for sketching synthesized textures. Reaction-Diffusion (RD) is used as the basis for texture synthesis. RD allows an unlimited amount of non-repeating texture and offers ...
  • Modeling Plant Variations through 3D Interactive Sketches 

    Streit, Lisa; Lapides, Paul; Sousa, Mario Costa; Sharlin, Ehud (The Eurographics Association, 2006)
    Modeling realistic looking plants is still a complex problem requiring specification of plant structure, geometry and surface characteristics. Modeling a collection of plants is more problematic especially since each plant ...
  • A New Sketch Based Interface using the Gray-level Co-occurrence Matrix for Perceptual Simplification of Paper Based Scribbles 

    Bartolo, Alexandra; Camilleri, Kenneth P.; Farrugia, Philip J.; Borg, Jonathan C. (The Eurographics Association, 2006)
    The sketching activity has an important role in conceptual design and a variety of tools exist which help designers to facilitate the generation of 3D models form sketched drawings. This paper describes a new sketch-to-3D ...
  • Transformation Strokes 

    Severn, Aaron; Samavati, Faramarz; Sousa, Mario Costa (The Eurographics Association, 2006)
    In this paper, we present a sketch-based technique for specifying transformations for general models by means of a single stroke, offering a more streamlined form of user interaction. The shape of the stroke is interpreted ...
  • Construction and Modification of 3D Geometry Using a Sketch-based Interface 

    Kara, Levent Burak; Shimada, Kenji (The Eurographics Association, 2006)
    We present an interactive pen-based computer program for designing 3D objects through direct sketching. The proposed techniques are tailored toward the creation of free-form curves and surfaces, and are therefore particulary ...
  • Parts, Image, and Sketch based 3D Modeling Method 

    Murakawa, Jun; Yoon, Ilmi; Hong, Tracie; Lank, Edward (The Eurographics Association, 2006)
    Despite their many benefits, challenges exist in the creation of 3D models, particularly for individual not currently skilled with 3D modeling software. To address this, we explore the creation of 3D modeling software for ...
  • Producing Models From Drawings of Curved Surfaces 

    Kaplan, Matthew; Cohen, Elaine (The Eurographics Association, 2006)
    We present a method for creating 2 1 2D models from line drawings of opaque solid objects. We allow the artist to draw naturally, differing from many previous approaches. Our system allows both perspective and orthographic ...
  • Parsing Ink Annotations on Heterogeneous Documents 

    Wang, Xin; Shilman, Michael; Raghupathy, Sashi (The Eurographics Association, 2006)
    Annotation is an integral part of reading, comprehending, commenting, and authoring notes and documents. In this paper we present a system for recognizing annotations in a flexible digital notebook that may contain a variety ...
  • Constellation Models for Sketch Recognition 

    Sharon, Dana; Panne, Michiel van de (The Eurographics Association, 2006)
    Sketch-based modeling shares many of the difficulties of the branch of computer vision that deals with single image interpretation. Most obviously, they must both identify the parts observed in a given 2D drawing or image.We ...
  • Automatic Interpretation of Proofreading Sketches 

    Rodríguez, Jose A.; Sánchez, Gemma; Lladós, Josep (The Eurographics Association, 2006)
    We present a sketch-based system for proofreading documents. The gestures and words drawn by the proofreader on a document view are translated into high-level actions that represent editions such as replace, insert, delete ...
  • Automatic Learning of Symbol Descriptions Avoiding Topological Ambiguities 

    Mas, Juan; Lamiroy, Bart; Sanchez, Gemma; Llados, Josep (The Eurographics Association, 2006)
    In this paper we address both automatic recognition of sketched symbols and the construction of the corresponding models from user drawn examples. Our approach is based on a two stage process. In a first phase we use an ...
