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 ...
Supporting Reinterpretation in Computer-Aided Conceptual Design
(The Eurographics Association, 2008)
This paper presents research that aims to inform the development of computational tools that better support design exploration and idea transformation - key objectives in conceptual design. Analyses of experimental data ...
ShortStraw: A Simple and Effective Corner Finder for Polylines
(The Eurographics Association, 2008)
In this paper we introduce ShortStraw, a simple and highly accurate polyline corner finder. ShortStraw uses a bottom-up approach to find corners by: (1) resampling the points of the stroke, (2) calculating the straw ...
From Paper to Machine: Extracting Strokes from Images for use in Sketch Recognition
(The Eurographics Association, 2008)
Sketching is a way of conveying ideas to people of diverse backgrounds and culture without any linguistic medium. With the advent of inexpensive tablet PCs, online sketches have become more common, allowing for stroke-based ...
SOUSA: Sketch-based Online User Study Applet
(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 ...
Rapid Sketch Modeling of Clouds
(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 ...
CogSketch: Open-domain Sketch Understanding for Cognitive Science Research and for Education
(The Eurographics Association, 2008)
In this paper, we describe CogSketch, an open-domain sketch understanding system built on the nuSketch architecture. CogSketch captures the multi-modal, unconstrained nature of sketching by focusing on reasoning over ...
Using Sketches and Retrieval to Create LEGO Models
(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 ...
Sketch-based Parameterization of L-systems using Illustration-inspired Construction Lines
(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 ...
Sketching Piecewise Clothoid Curves
(The Eurographics Association, 2008)
We present a novel approach to sketching 2D curves with minimally varying curvature as piecewise clothoids. A stable and efficient algorithm fits a sketched piecewise linear curve using a number of clothoid segments with ...
