We describe a virtual sculpture environment suited to the needs of artists. In this approach, the user is immersed in a virtual environment by the use of haptic devices and immersive display. The project is focused around four main research topics: the sculpture model, the tools and their actions on the model, the display of the sculpture, and the interface between the artist and its virtual wo...

statement of problem: pit and fissure sealant therapy has been approved as an effective measure in the prevention of occlusal dental caries. resin based ma- terials are the most common materials used worldwide. a variety of resin based fissure sealants are produced and used. most of them have been presented with ideal results in research environment. however, their effectiveness in the real lif...

background pit-and-fissure sealants are safe and effective ways to prevent dental caries and are considered as a part of an overall caries-preventive strategy. dental caries are a public health problem and the most common intraoral disease affecting mankind. it is an infectious transmissible disease, with the child patient being at the highest risk. objectives the purpose of this study was to e...

one of the main concerns of the mining industry is to determine ultimate pit limits. final pit is a collection of blocks, which can be removed with maximum profit while following restrictions on the slope of the mine’s walls. the size, location and final shape of an open-pit are very important in designing the location of waste dumps, stockpiles, processing plants, access roads and other surfac...

objectives: application of sealants is a safe and effective way to prevent occlusal caries in the posterior teeth. a successful sealant therapy depends on good isolation. decreased steps of adhesive application may enable proper isolation and use of self-adhering flowable composites for sealant therapy. this study sought to compare the marginal microleakage of fissure sealants and self-adhering...

We propose here a sculpture metaphor for rapid shape prototyping. This metaphor makes the underlying surface description transparent for the user, enabling him to focus only on the shape being modeled. Our approach is based on implicit surfaces defined as iso-surfaces over a discrete field.

This paper will examine the development of emotion in Greek sculpture; beginning with its overall absence in the Late Archaic period and continuing through its inception in the Early Classical period and its zenith during the Hellenistic Age. My chapters will each focus on a different style of sculpture and how emotion developed in each of them. I begin with architectural sculpture, tracing how...

Résumé : Nous présentons ici une métaphore de sculpture destinée au prototypage rapide de formes 3D. La surface sculptée correspond à l’iso-valeur d’un champ potentiel scalaire échantillonné spatiallement. L’utilisateur peut déposer de la matière où il le désire dans l’espace puis itérativement affiner sa forme grâce à un outil servant à déposer, retirer, peindre ou lisser de la matière, comme ...

theoretical review of ‘mining pit lakes’ indicates that like natural lakes such lakes display a huge diversity. they are typically in a non-equilibrium state with respect to their surroundings. hence, at the decommissioning phase of mining operation a detailed technical study are required on different aspects of such created water bodies considering its morphometry, geology, hydrology, water qu...
