Hardware and software improvements of volume splatting
(2006-05)
Report de recerca.
Accés obert
Report de recerca.
Accés obert
This paper proposes different hardware-based acceleration of the three classical splatting strategies: emph{composite-every-sample}, emph{object-space sheet-buffer} and emph{image-space sheet-buffer}.
Geometric objects in Blender 2.32
(2004-05)
Report de recerca.
Accés obert
Report de recerca.
Accés obert
The aim of this document is to explore the way that Blender 2.32 stores the information for modeling static scenes. First, the conceptual model the system uses to store geometric objects is explained, guiding the user to ...
La modularidad de la mente: origen y transformación de una metáfora
(2001-05)
Report de recerca.
Accés obert
Report de recerca.
Accés obert
In this work we try to make clear the actual reference of the modular hypothesis of the mind, and the epistemological and ontological relevance of the metaphor. We also make a critical evaluation of the
contribution of ...
Dynamic geometry based on geometric constraints
(2007-07)
Report de recerca.
Accés obert
Report de recerca.
Accés obert
Dynamic geometry systems are tools for geometric visualization. They allow the user to define geometric elements, establish relationships between them and explore the dynamic behavior of the remaining geometric elements ...
Regular triangulations of dynamic sets of points
(2000-10)
Report de recerca.
Accés obert
Report de recerca.
Accés obert
The Delaunay triangulations of a set of points are a class of
triangulations which play an important role in a variety of
different disciplines of science. Regular triangulations are a
generalization of Delaunay ...
Integration of multimodal data based on surface registration
(2000-11)
Report de recerca.
Accés obert
Report de recerca.
Accés obert
The paper proposes and evaluates a strategy for the alignment of
anatomical and functional data of the brain. The method takes as an
input two different sets of images of a same patient: MR data and
SPECT. ...
Two triangulations methods based on edge refinement
(2003-03)
Report de recerca.
Accés obert
Report de recerca.
Accés obert
In this paper two curvature adaptive methods of surface triangulation
are presented. Both methods are based on edge refinement to obtain a
triangulation compatible with the curvature requirements. The first
method applies ...
An improved boundary extraction algorithm using a plane-sweep technique
(2006-06)
Report de recerca.
Accés obert
Report de recerca.
Accés obert
Extracting the boundary of a 3D or a 2D image is a fundamental operation in several image processing related fields. In other fields as NC-data generation, obtaining the cutting areas of sculptured surfaces can be performed ...
Fast connected component labeling algorithm: a non voxel-based approach
(2002-03)
Report de recerca.
Accés obert
Report de recerca.
Accés obert
This paper presents a new approach to achieve connected component labeling on both binary images and volumes by using the Extreme Vertices Model (EVM), a representation model for orthogonal
polyhedra, applied to digital ...
Time-varying volume visualization
(2005-07-22)
Report de recerca.
Accés obert
Report de recerca.
Accés obert
Volume rendering is a very active research field in Computer Graphics because of its wide range of applications in various sciences, from medicine to flow mechanics. In this report, we survey a state-of-the-art on time-varying ...
