“…One can compute a texture to be applied on a compressed version of the original model in order to approximate the appearance of the full resolution coloured model ( Figure 8). An algorithm for the automatic generation of this map is coupled with the vertex removal mesh compression method [13]. It requires that, during the geometric compression, the algorithm keep track of where each removed vertex projects on the compressed version of the model.…”

The National Research Council of Canada (NRC) has developed and patented three high‐resolution 3D imaging systems and processing algorithms which have been applied to a wide range of museum and heritage recording applications. The systems have been designed for different imaging applications and, in collaboration with a number of national and international museums and cultural agencies, have been used to scan a wide variety of objects and sites. The objective of this paper is to present a summary of the 3D technology and examples of its heritage applications. Copyright © 2003 John Wiley & Sons, Ltd.

“…On comprendra ici que rédiger une prescription « sur-lechamp » s'avère plus rapide, et même plus apprécié des patients, que d'interroger ceux-ci en profondeur en leur proposant éventuellement de modifier quelques-uns de leurs comportements (habitudes de vie) pour éviter que les problèmes pour lesquels ils consultent ne se manifestent à nouveau. Bref, il n'est pas surprenant de constater qu'on utilise, avec exagération même, la prescription de médicaments, comme dans le cas des antibiotiques (GRAVEL, 2003 ;PC, 2003) et des antidépresseurs, entre autres pour les jeunes de moins de 20 ans (RIOUX SOUCY, 2004). Or, on sait aujourd'hui que cette médicamentation substitutive à la santé et à la relation de service médical humain conduit à une surmédicamentation de plus en plus prégnante, qui est responsable d'une détérioration de la santé et (ou) de la capacité « naturelle » de la recouvrer et, pire, d'un taux très élevé d'hospitalisation, particulièrement chez les personnes âgées et les dépressifs, dont le nombre ne cesse d'augmenter depuis plus de trente ans Il y a dans ce contexte de réorganisation structurelle des soins hospitaliers et médicaux un ensemble de facteurs, dont l'idéologie économiciste-productiviste présidant cette réorganisation des soins depuis un bonne quinzaine d'années, mais aussi d'autres causes sur lesquelles nous reviendrons en conclusion, qui conduisent plus ou moins directement à une sur-médicamentation systématique et systémique.…”

Nous analysons dans cet article la croissance des dépenses publiques et privées de santé au Québec. Plus spécifiquement, nous dégageons les grandes tendances des dépenses de santé associées aux médicaments de façon à comprendre la transformation qui a cours depuis plusieurs années, au chapitre de la prise en charge clinique de la maladie et des patients. L’effort consiste à mettre en lumière en quoi la société québécoise est de plus en plus modelée par une logique de prise en charge qui repose sur une médicamentation intensive et systémique, de fait une sur-médication, des services de soins offerts à la population québécoise.This paper presents an analysis of the growth in public and private health-related spending in Québec. More specifically, it identifies the major spending trends in health care, connected with medication, so as to understand the transformation that has been under way for a number of years, in the area of clinical treatment of illness and of patients. The focus is placed on showing how Québec society is increasingly adopting a treatment model based on intensive and systematic use of medication, in fact over-medication, in the health services provided to the Québec population

“…Our LOD-sprite is most closely related to the techniques of Cohen et al [4] and Soucy et al [25]. Both create a texture map from a 3D object represented at a high geometric resolution, and then subsequently represent the object at a much lower geometric resolution, but apply the previously created texture map to the geometry.…”

We present a new rendering technique, termed LOD-sprite rendering, which uses a combination of a level-of-detail (LOD) representation of the scene together with reusing image sprites (previously rendered images). Our primary application is accelerating terrain rendering. The LOD-sprite technique renders an initial frame using a high-resolution model of the scene geometry. It renders subsequent frames with a much lower-resolution model of the scene geometry and texture-maps each polygon with the image sprite from the initial high-resolution frame. As it renders these subsequent frames the technique measures the error associated with the divergence of the view position from the position where the initial frame was rendered. Once this error exceeds a user-defined threshold, the technique re-renders the scene from the high-resolution model. We have efficiently implemented the LOD-sprite technique with texture-mapping graphics hardware. Although to date we have only applied LOD-sprite to terrain rendering, it could easily be extended to other applications. We feel LOD-sprite holds particular promise for real-time rendering systems.
