This report describes an algorithm for the generation of unstructured tetrahedral meshes from two triangular meshes: the internal and external walls of an object. The tetrahedral mesh thus obtained represents the volume ...

Conventional treatment of the subcondylar fractures of the mandible is challenging because of the medial and anterior displacement of the condylar fragment and the limited surgical field. Proximity of facial nerve, carotid ...

The haptic rendering of surface mesostructure (fine relief features) in dense triangle meshes requires special structures, equipment, and high sampling rates for detailed perception of rugged models. Some approaches simulate ...

Implicit surface poligonalization is an useful technique for visualizing sampled volumetric data in many scientific applications. In this report we describe some of the different algorithms for constructing poligonazed ...

In many application areas, it is useful to convert the discrete information stored in the nodes of a regular grid into a continuous boundary model. Isosurface extraction algorithms di er on how the discrete information in ...

Background: Some patients complain that eating lettuce, gives them gas and abdominal distention. Our aim was to determine to what extent the patients' assertion is sustained by evidence. Methods: An in vitro study measured ...

Medical illustrations have been used for a long time for teaching and communicating information for diagnosis or surgery planning. Illustrative visualization systems create methods and tools that adapt traditional illustration ...

Throughout the years, many shading techniques have been developed to improve the conveying of information in volume visualization. Some of these methods, usually referred to as realistic, are supposed to provide better ...

Although the visualization techniques are becoming faster and faster, the datasets also increase, and the time the radiologists are able to devote to a single analysis is limited. In this sense, we propose some techniques ...

This paper describes the Extended Octree model that are an exact representation for polyhedra. Boolean Operations in this model perform in linear time, as they include an implicit spacial localization of the objects. As a ...
