Visual Languages and Visual Thinking: Sketch Based Interaction and Modeling
(The Eurographics Association, 2009)
Research on sketching with computers dates to the earliest days of modern computing. Recent work in this area, combined with other advances in hardware and software technologies promises, finally, significant impact. The ...
An Initial Evaluation of a Pen-Based Tool for Creating Dynamic Mathematical Illustrations
(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 Subdivision Models
(The Eurographics Association, 2009)
Designing a control mesh (or a polyhedron) for a subdivision model is a tedious task. It involves many difficult decisions such as how to minimize the number of extraordinary vertices, how best to choose their valencies, ...
Applying Scenarios in User-Centred Design to Develop a Sketching Interface for Human Modelling and Animation
(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 ...
Modeling Plant Variations through 3D Interactive Sketches
(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 ...
Retrieving Web Page Layouts using Sketches to Support Example-based Web Design
(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. ...
Example-Based Conceptual Styling Framework for Automotive Shapes
(The Eurographics Association, 2007)
Conceptual design in the automotive industry is a time-consuming process. Iterations between concept sketches, created with traditional two dimensional methods, and 3D digital representations of a prototype are currently ...
A New Sketch Based Interface using the Gray-level Co-occurrence Matrix for Perceptual Simplification of Paper Based Scribbles
(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 ...
A Simple-to-Implementation Method for Cutting a Mesh Model by a Hand-Drawn Stroke
(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 ...
Volume Painter: Geometry-Guided Volume Modeling by Sketching on the Cross-Section
(The Eurographics Association, 2008)
We propose a sketch-based system to design volume data from scratch. The user splits a surface model and paints brush strokes to volumetrically fill the 3D space. We extend exisiting sketch-based modeling systems in various ...
