    Israel, Johann Habakuk; Zöllner, Christian; Mateescu, Magda; Korkot, Rasim; Bittersmann, Gunnar; Fischer, Patrick Tobias; Neumann, Jens; Stark, Rainer (The Eurographics Association, 2008)
    As immersive 3-d user interfaces reach broader acceptance, their use as sketching media is attracting both commercial and academic research. So far little is known about user requirements and cognitive aspects of immersive ...
  • Sketching Faces 

    Gunnarsson, Orn; Maddock, Steve (The Eurographics Association, 2008)
    Faces can be modelled using a number of techniques. Existing faces can be transferred to a digital form using equipment such as laser scanners. New faces can be constructed using commercial modelling tools, or using ...
  • Sketch-Based Search and Composition of 3D Models 

    Lee, Jeehyung; Funkhouser, Thomas (The Eurographics Association, 2008)
    There is growing interest in developing tools with which novice users can create detailed 3D models of their own designs. The most popular approaches to this problem include sketch-based interfaces and part-composition ...
  • Rapid Sketch Modeling of Clouds 

    Wither, Jamie; Bouthors, Antoine; Cani, Marie-Paule (The Eurographics Association, 2008)
    Clouds are an important visual element of any natural scene and computer artists often wish to create specific cloud shapes (for example in the film Amélie, as depicted in Fig 1). We describe a sketch based interface for ...
  • Sketch-based Parameterization of L-systems using Illustration-inspired Construction Lines 

    Anastacio, Fabricio; Prusinkiewicz, P.; Sousa, Mario Costa (The Eurographics Association, 2008)
    We present a sketch-based interface for parameter control of rule-based models. It allows intuitive specification and creation of plant structures with L-systems. Construction lines inspired by concept sketches are employed ...
  • A Data Collection Tool for Sketched Diagrams 

    Blagojevic, Rachel; Plimmer, Beryl; Grundy, John; Wang, Yong (The Eurographics Association, 2008)
    Repositories of digital ink sketches would be invaluable for testing and evaluation of sketch recognition software. However, there is no existing tool for flexible data collection and management of digital ink data for ...
  • SOUSA: Sketch-based Online User Study Applet 

    Paulson, Brandon; Wolin, Aaron; Johnston, Joshua; Hammond, Tracy (The Eurographics Association, 2008)
    Although existing domain-specific datasets are readily available, most sketch recognition researchers are forced to collect new data for their particular domain. Creating tools to collect and label sketched data can take ...
  • Using Sketches and Retrieval to Create LEGO Models 

    Santos, Tiago; Ferreira, Alfredo; Dias, Filipe; Fonseca, Manuel J. (The Eurographics Association, 2008)
    In this paper we describe a system to create LEGO models using sketches. Although there are a few applications to create LEGO models, they are difficult to use, mainly due to the searching and manipulation mechanisms that ...
  • A Sketch-Based Method to Control Deformation in a Skeletal Implicit Surface Modeler 

    Sugihara, Masamichi; Groot, Erwin de; Wyvill, Brian; Schmidt, Ryan (The Eurographics Association, 2008)
    Skeletal implicit surfaces offer many advantages for sketch-based modeling systems, such as blending, CSG, and a procedural object hierarchy. Free-form deformation (FFD) is also extremely useful in this context, however ...
  • Matisse: Painting 2D regions for Modeling Free-Form Shapes
