3D simulation of tool machining
(2001-12)
External research report
Open AccessThis paper describes a three-dimensional tool machining simulation system. The initial tool and the grinding wheels are integrated with the machine-tool. The application reads and interprets the CNC program code that ... -
A Fast hierarchical traversal strategy for multimodal visualization
(2003-09)
External research report
Open AccessIn the last years there is a growing demand of multimodal medical rendering systems able to visualize simultaneously data coming from different sources. This paper addresses the Direct Volume Rendering (DVR) of aligned ... -
An Adaptive Cutaway with Volume Context Preservation
(Springer Berlin / Heidelberg, 2009-11-26)
Part of book or chapter of book
Restricted access - publisher's policyKnowledge expressiveness of scientific data is one of the most important visualization goals. However, current volume visualization systems require a lot of expertise from the final user. In this paper, we present a ... -
A Volume Visualization Algorithm using a coherent Extended Weight Matrix
(1995-01)
Article
Restricted access - publisher's policyDirect cell-to-cell volume visualization algorithms, also called projective rendering methods, present the advantage of allowing semi-transparencies and, additionally, as they project all the samples, they avoid the ... -
Cerebral blood vessels modeling
(1998-04)
External research report
Open AccessCerebral vascular diseases are complex to analyze directly from the input data captions offered by Computer Tomographies and Magnetic Resonances because the cerebral blood vessels are small and narrow. In this report, ... -
Design of a multimodal rendering system
(2002-05)
External research report
Open AccessThis paper addresses the rendering of aligned regular multimodal datasets. It presents a general framework of multimodal data fusion that includes several data merging methods. We also analyze the requirements ... -
Discrete medial axis transform for discrete objects
(1998-04)
External research report
Open AccessThe Medial Axis Transform MAT was defined by Blum as an alternate description of the shape of a continuous object. The MAT is the closure of the set of centers of maximal balls which can fit inside the object. A ball ... -
Discrete medial axis transform for discrete thin and elongated objects
(1999-12)
External research report
Open AccessSkeletons are compact shape descriptions of discrete images. They have been extensively studied because of their utility in various applications such as data compression, shape abstraction, navigation and features detection. ... -
Efficient complementary viewpoint selection in volume rendering
(2013)
Conference report
Open AccessA major goal of visualization is to appropriately express knowledge of scientific data. Generally, gathering visual information contained in the volume data often requires a lot of expertise from the final user to setup ... -

Hybrid model for vascular tree structures
(1999-12)
External research report
Open AccessThis paper proposes a new representation scheme of the cerebral blood vessels. This model provides information on the semantics of the vascular structure: the topological relationships between vessels and the ... -
Intelligent interactive volume classification
(2013)
Conference report
Restricted access - publisher's policyThis paper defines an intelligent and interactive framework to classify multiple regions of interest from the original data on demand, without requiring any preprocessing or previous segmentation. The proposed intelligent ... -
Non-homogeneous solid modeling with octrees. A geological application
(1993-03)
External research report
Open AccessFrom an historical point of view, geometric modeling techniques usually represent the surface of solids. However, the increasing development of new fields in CAD applications like molecular systems, medicine, or geology, ... -
Region-based illustrative visualization of multimodal datasets
(2013-06-01)
Article
Restricted access - publisher's policyWe present as novel method for the exploration of multiple overlapping volumes that provides flexibility to merge data in different ways in different regions. In each region, either one of the modalities is rendered alone ... -
Rendering techniques for multimodal data
(2002-02)
External research report
Open AccessMany different direct volume rendering methods have been developed to visualize 3D scalar fields on uniform rectilinear grids. However, little work has been done on rendering simultaneously various properties of the same ... -
Research trends in volume modeling
