3D texture-based hybrid visualizations
(2003-01)
Article
Accés restringit per política de l'editorialIn this paper, the visualization of hybrid scenes that contain volume data and a fitted extracted surface is addressed. The proposed algorithm is based on a integrated octree-based representation: the ‘‘hybrid octree.’’ ... -
An octree isosurface codification based on discrete planes
(2001)
Text en actes de congrés
Accés obertDescribes a method to code a decimated model of an isosurface on an octree representation while maintaining volume data if it is needed. The proposed technique is based on grouping the marching cubes (MC) patterns into ... -
Analog circuits testing using digitally coded indirect measurements
(Institute of Electrical and Electronics Engineers (IEEE), 2015)
Text en actes de congrés
Accés restringit per política de l'editorialTesting mixed-signal circuits is a challenging task requiring high amounts of human and technical resources. To overcome these drawbacks, indirect testing methods have been adopted as an efficient solution to perform ... -
Criteria for indirect measurements in M-S testing
(2014)
Text en actes de congrés
Accés restringit per decisió de l'autorAnalog and mixed-signal circuit testing is a cballenging task demanding large amounts of resources. In order to battle against this drawback, alternate testing has been established as an eflicient way of testing analog ... -
Criteria for selecting a subset of indirect measurements for analog testing
(2016)
Text en actes de congrés
Accés restringit per política de l'editorialThis work proposes a criterion to select a subset of indirect measurements avoiding redundant information. The key idea of the proposal is to reduce the actual number of measurements to be performed to those strictly ... -
Efficient algorithms for boundary extraction of 2D and 3D orthogonal pseudomanifolds
(2011)
Report de recerca
Accés obertIn this paper we present algorithms to extract the boundary representation of orthogonal polygons and polyhedra, either manifold or pseudomanifold. The algorithms we develop reconstruct not only the polygons of the boundaries ... -
Efficient production binning using octree tessellation in the alternate measurements space
(2015)
Article
Accés obertBinning after volume production is a widely accepted technique to classify fabricated ICs into different clusters depending on different degrees of specification compliance. This allows the manufacturer to sell non optimal ... -
Geometric transformations in octrees using shears
(1997-12)
Report de recerca
Accés obertExistent algorithms to perform geometric transformations on octrees can be classified in two families: inverse transformation and address computation ones. Those in the inverse transformation family essentially resample ... -
Indirect test of M-S circuits using multiple specification band guarding
(2016-09-01)
Article
Accés obertTesting analog and mixed-signal circuits is a costly task due to the required test time targets and high end technical resources. Indirect testing methods partially address these issues providing an efficient solution using ... -
Integrating occlusion culling and levels of detail through hardly-visible sets
(North Holland, 2000-12)
Article
Accés restringit per política de l'editorialOcclusion culling and level-of-detail rendering have become two powerful tools for accelerating the handling of very large models in real-time visualization applications. We present a framework that combines both techniques ... -
M-S test based on specification validation using octrees in the measure space
(2013)
Text en actes de congrés
Accés restringit per política de l'editorialTesting M-S circuits is a difficult task demanding high amount of resources. To overcome these drawbacks, indirect testing methods have been adopted as an efficient solution to perform specification based tests using easy ... -
Non-homogeneous solid modeling with octrees. A geological application
(1993-03)
Report de recerca
Accés obertFrom 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, ... -
Object representation by means of nonminimal division quadtrees and octrees
(1985-01)
Article
Accés restringit per política de l'editorialQuadtree representation of two-dimensional objects is performed with a tree that describes the recursive subdivision of the more complex parts of a picture until the desired resolution is reached. At the end, all the leaves ... -
Solid representation and operation using extended octrees
(1990-04)
Article
Accés restringit per política de l'editorialSolid modelers must be based on reliable and fast algorithms for Boolean operations. The octree model, as well as several generalizations (polytrees, integrated polytrees, extended octrees), is specially well suited for ... -
The Hybrid Octree: towards the definition of a multiresolution hybrid framework
(2002)
Text en actes de congrés
Accés restringit per política de l'editorialThe Hybrid Octree (HO) is an octree-based representation scheme for coding in a single model an exact representation of a surface and volume data. The HO is able to efficiently manipulate surface and volume data independently. ...
