Barycentric Coordinates on Surfaces
(2010)
This paper introduces a method for defining and efficiently computing barycentric coordinates with respect to polygons on general surfaces. Our construction is geared towards injective polygons (polygons that can be enclosed ...
Feature-Driven Ambient Occlusion for Direct Volume Rendering
(The Eurographics Association, 2010)
Ambient occlusion techniques were introduced to improve data comprehension by bringing soft fading shadows. They consist in attenuating light by considering the occlusion resulting from the presence of neighboring structures. ...
Constraint-Based Simulation of Adhesive Contact
(The Eurographics Association, 2010)
Dynamics with contact are often formulated as a constrained optimization problem. This approach allows handling in an integrated manner both non-penetration and frictional constraints. Following developments in the ...
Feature Extraction and Classifier Combination for Image-based Sketch Recognition
(The Eurographics Association, 2010)
Image-based approaches to sketch recognition typically cast sketch recognition as a machine learning problem. In systems that adopt image-based recognition, the collected ink is generally fed through a standard three stage ...
Cross-Node Occlusion in Sort-Last Volume Rendering
(The Eurographics Association, 2010)
In the field of parallel volume rendering, occlusion is a concept which is already widely exploited in order to improve performance. However, when one moves to larger datasets the use of parallelism becomes a necessity, ...
Realtime Aesthetic Image Retargeting
(The Eurographics Association, 2010)
Humans have always sought to achieve aesthetics in art. In this paper, we present a novel approach for retargeting images to different aspect ratios while improving the composition aesthetics of the results. A simpler ...
Rata.SSR: Data Mining for Pertinent Stroke Recognizers
(The Eurographics Association, 2010)
While many approaches to digital ink recognition have been proposed, most lack flexibility and adaptability to provide acceptable recognition rates across a variety of problem spaces. Time and expert knowledge are required ...
Shape Modeling with Sketched Feature Lines in Immersive 3D Environments
(The Eurographics Association, 2010)
In this paper we address the question whether automatic shape creation using sketched strokes as input in an immersive 3D environment supports the sketching process in early phases of product design. To investigate this ...
A Sketching Interface for Sitting-Pose Design
(The Eurographics Association, 2010)
We present a sketch interface for interactively placing a 3D human character in a sitting position on a chair. The user first sketches the target pose as a 2D stick figure. The user can specify whether a joint will be ...
Exploring Frame Gestures for Fluid Freehand Sketching
(The Eurographics Association, 2010)
In this paper, we explore a minimalistic, gesture-based interface for fluid freehand concept sketching with vector graphics. Our approach leverages the advantages of both the GUI and gestural interface paradigms. We describe ...
