Fast Navigation through an FRep Sculpture Garden
The function representation (FRep) allows for construction of quite complex shapes such as isosurfaces of real-valued functions composed using the functionally defined primitives and operations. Calculating such functions in the complex cases can be very time-consuming. Extraction and visualization of isosurfaces for them can hardly be imagined interactive. In this paper we present a method of ...
متن کاملOn the Number of Guards in Sculpture Garden Problem
In this paper, we consider the problem of placing a small number of angle guards inside a simple polygon P such that each point in the plane can determine if it is in or out of P from a monotone Boolean formula (and (.) and or (+) operations only) composed from the angle guards. Each angle guard views an infinite wedge of the plane. This class of new art gallery type problems is called sculptur...
متن کاملVirtual Sculpture
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.
متن کاملSculpture virtuelle
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 ...
