Direct Visualization of Deformation in Volumes
(The Eurographics Association and Blackwell Publishing Ltd., 2009)
Deformation is a topic of interest in many disciplines. In particular in medical research, deformations of surfaces and even entire volumetric structures are of interest. Clear visualization of such deformations can lead ...
Spring-Based Manipulation Tools for Virtual Environments
(The Eurographics Association, 2001)
In this paper we present new tools for user interaction with virtual worlds, to bring more natural behavior into the manipulation of objects in virtual environments. We present some principles of physically realistic ...
PDRIVE: The Projector-based, Desktop, Reach-In Virtual Environment
(The Eurographics Association, 2007)
This paper presents the Projector-based, Desktop, Reach-In Virtual Environment, or PDRIVE. A PDRIVE user reaches in to the virtual environment, which he views through a mirror. Stereo images are generated by two standard, ...
Visual Consistency in Rotational Manipulation Tasks in Sheared-Perceived Virtual Environments
(The Eurographics Association, 2007)
Sharing one large screen projection display, such as the Virtual Workbench, with multiple users can cause distortions in viewing and interaction, as the users perceive a sheared and moving space. Generally, object rotation ...
IntenSelect: Using Dynamic Object Rating for Assisting 3D Object Selection
(The Eurographics Association, 2005)
We present IntenSelect, a novel selection technique that dynamically assists the user in the selection of 3D objects in Virtual Environments. Ray-casting selection is commonly used, although it has limited accuracy and can ...
Virtual Spring Manipulators for Particle Steering in Molecular Dynamics on the ResponsiveWorkbench
(The Eurographics Association, 2002)
In this paper we present new virtual spring manipulator-based tools for steering particles in molecular dynamics simulations in virtual environments. We briefly overview the MolDRIVE system, our visualization and computational ...
Fast Normal Vector Compression with Bounded Error
(The Eurographics Association, 2007)
We present two methods for lossy compression of normal vectors through quantization using base polyhedra. The first revisits subdivision-based quantization. The second uses fixed-precision barycentric coordinates. For ...
Surface Curvature Line Clustering for Polyp Detection in CT Colonography
(The Eurographics Association, 2008)
Automatic polyp detection is a helpful addition to laborious visual inspection in CT colonography. Traditional detection methods are based on calculating image features at discrete positions on the colon wall. However ...
Interactive Previewing for Transfer Function Specification in Volume Rendering
(The Eurographics Association, 2002)
This paper presents a new technique for supplying meaningful visual feedback during direct volume rendering transfer function specification. The technique uses meta-data calculated during a pre-processing step to generate ...
Hybrid Interfaces in VEs: Intent and Interaction
(The Eurographics Association, 2006)
Hybrid user interfaces (UIs) integrate well-known 2D user interface elements into the 3D virtual environment, and provide a familiar and portable interface across a variety of VR systems. However, their usability is often ...
