Context Aware Terrain Visualization for Wayfinding and Navigation
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
To assist wayfinding and navigation, the display of maps and driving directions on mobile devices is nowadays commonplace. While existing system can naturally exploit GPS information to facilitate orientation, the inherently ...
Automatic Facsimile of Chinese Calligraphic Writings
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
Online Personalised Non-photorealistic Rendering Technique for 3D Geometry from Incremental Sketching
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
This paper presents an online personalised non-photorealistic rendering (NPR) technique for 3D models generated from interactively sketched input. This technique has been integrated into a sketch-based modelling system. ...
Part-type Segmentation of Articulated Voxel-Shapes using the Junction Rule
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
We present a part-type segmentation method for articulated voxel-shapes based on curve skeletons. Shapes are considered to consist of several simpler, intersecting shapes. Our method is based on the junction rule: the ...
A Hidden-picture Puzzles Generator
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
A hidden-picture puzzle contains objects hidden in a background image, in such a way that each object fits closely into a local region of the background. Our system converts image of the background and objects into line ...
Patch-type Segmentation of Voxel Shapes using Simplified Surface Skeletons
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
We present a new method for decomposing a 3D voxel shape into disjoint segments using the shape s simplified surface-skeleton. The surface skeleton of a shape consists of 2D manifolds inside its volume. Each skeleton point ...
A Biorthogonal Wavelet Approach based on Dual Subdivision
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
In this paper a biorthogonal wavelet approach based on Doo-Sabin subdivision is presented. In the dual subdivision like Doo-Sabin scheme, all the old control vertices disappear after one subdivision step, which is a big ...
Efficient CPU-based Volume Ray Tracing Techniques
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
Recent research on high-performance ray tracing has achieved real-time performance even for highly complex surface models already on a single PC. In this report, we provide an overview of techniques for extending real-time ...
A survey on Mesh Segmentation Techniques
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
We present a review of the state of the art of segmentation and partitioning techniques of boundary meshes. Recently, these have become a part of many mesh and object manipulation algorithms in computer graphics, geometric ...
Point-Based Rendering of Non-Manifold Surfaces
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
We are concerned with producing high-quality images of parametric and implicit surfaces, in particular those with non-manifold features. We present a point-based technique for rendering implicit surfaces that uses octree ...
