Extracting Boundary Surface of Arbitrary Topology from Volumetric Datasets
(The Eurographics Association, 2001)
This paper presents a novel, powerful reconstruction algorithm that can recover correct shape geometry as well as its unknown topology from arbitrarily complicated volumetric datasets. The algorithm starts from a simple ...
A Volume Modeling Component of CAD
(The Eurographics Association, 2001)
This paper presents a framework we have developed for modeling and manipulation of volumetric data sets. It is a set of new functions integrated into a CAD system. We shall address freeform modeling through voxelization ...
A Survey of Methods for Volumetric Scene Reconstruction from Photographs
(The Eurographics Association, 2001)
Scene reconstruction, the task of generating a 3D model of a scene given multiple 2D photographs taken of the scene, is an old and difficult problem in computer vision. Since its introduction, scene reconstruction has found ...
Data Level Comparison of Surface Classification and Gradient Filters
(The Eurographics Association, 2001)
Surface classification and shading of three dimensional scalar data sets are important enhancements for direct volume rendering (DVR). However, unlike conventional surface rendering, DVR algorithms do not have explicit ...
A Framework to Visualize and Interact with Multimodal Medical Images
(The Eurographics Association, 2001)
The simultaneous use of images obtained from different sources is common in medical diagnosis. However, even though the quality of these images has been improving, the integration of multimodality data into a unique 3D ...
Real-Time Volume Rendering for Virtual ColonoscopyS
(The Eurographics Association, 2001)
We present a volume rendering system that is capable of generating high-quality images of large volumetric data (e.g., 512<sup>3</sup>) in real time (30 frames or more per second). The system is particularly ...
Translucent and Opaque Direct Volume Rendering for Virtual Endoscopy Applications
(The Eurographics Association, 2001)
Virtual endoscopy applications frequently require the visual representation of several material interfaces to show the relevant data feature to the user. This requires the specification of complex transfer function which ...
EXOMIO: A 3D Simulator for External Beam Radiotherapy
(The Eurographics Association, 2001)
Simulators are medical devices used in the oncology clinics to perform the simulation procedure for the external beam radiotherapy treatment. Unlikely for a clinic to obtain a real Simulator is a high investment in terms ...
Volume Visualization of Payoff Regions for Derivatives Risk Management
(The Eurographics Association, 2001)
Volume visualization of derivatives helps us discover risks, which hitherto have been elusive with traditional surface plots. In this paper, we would like to address the volatility visualization issue, which is one of the ...
Two-Pass Image and Volume Rotation
(The Eurographics Association, 2001)
We present a novel two-pass approach for both 2D image and 3D volume rotation. Each pass is a pseudo shear. However, it has a similar regularity as a pure shear in that a beam remains rigid while being sheared. Furthermore, ...
