      Varley, P. A. C.; Martin, R. R.; Suzuki, H. (The Eurographics Association, 2005)
      Freehand sketching is an important part of the conceptual design process, and the increasing number of recent sketching applications shows a developing awareness of this importance. We aim to provide an automated tool to ...
    • Retrieving Web Page Layouts using Sketches to Support Example-based Web Design 

      Hashimoto, Yasunari; Igarashi, Takeo (The Eurographics Association, 2005)
      It is very difficult for inexperienced users to design good-looking web page layouts. Even with WYSIWYG editors, it is still difficult to obtain desired results because one must combine complicated HTML specific structures. ...
    • ShapeShop: Sketch-Based Solid Modeling with BlobTrees 

      Schmidt, Ryan; Wyvill, B.; Sousa, M. C.; Jorge, J. A. (The Eurographics Association, 2005)
      Various systems have explored the idea of inferring 3D models from sketched 2D outlines. In all of these systems the underlying modeling methodology limits the complexity of models that can be created interactively. The ...
    • A Simple-to-Implementation Method for Cutting a Mesh Model by a Hand-Drawn Stroke 

      Mitani, Jun (The Eurographics Association, 2005)
      In the field of Computational Geometry, the design of 3D models using hand drawn strokes has been well-studied in recent years as a way to improve user interfaces. When using hand-drawn strokes to design 3D models, an ...
    • Sketch-Based Design for Bargello Quilts 

      Coahran, M.; Fiume, E. (The Eurographics Association, 2005)
      Quilting is an art form in which amateur craftspeople explore geometry and color to create stunning designs. Bargello is a specific quilt style defined by a clever construction method that imposes constraints on the designs ...
