Shape approximation algorithms aim at computing simple geometric descriptions of dense surface meshes. Many such algorithms are based on mesh decimation techniques, generating coarse triangulations while optimizing for a particular metric which models the distance to the original shape. This approximation scheme is very efficient when enough polygons are(More)
Figure 1: We performed a user study to evaluate several ground navigation metaphors. Top-left: Top view of the virtual city, users have to follow the green path as closely as possible. Top-right: At the beginning of the session, the available motions are displayed to the user, while her rest pose is captured. Bottom: a user is travelling in the scene while(More)
Performance capture systems are used to acquire high-quality animated 3D surfaces, usually in form of a dense 3D triangle mesh. Extracting a more compact yet faithful representation is often desirable, but existing solutions for animated sequences are surface based, which leads to a limited approximation power in the case of extreme simplification. We(More)
To assess the impact of restrictive civil commitment procedures, the authors studied the population of a prison psychiatric unit before and after the procedures were implemented. Their findings suggest that when the community finds it difficult to use the alternative of involuntary hospitalization, arrest and imprisonment are used to remove mentally ill(More)
Mosaic is a sketch-based system that simplifies and automates the creation of digital decorative mosaics from scratch. The creation of each tile piece of unique shape, color and orientation, in a complex mosaic is a tedious process. Our core contribution is two-fold: first, we present a new tile growing algorithm, that balances the shape and placement of(More)
In interactive shape modeling, surface selection is one of the basic, cornerstone interaction: this task may be performed hundreds of times by the user for the modification of a single shape. Despite the numerous automatic selection methods introduced in the literature, this remains a cumbersome operation in a number of scenarios, where the user is(More)
Page This booklet is about living and working on the attractive edges of the dynamic Great Lakes. There are risks from natural coastal hazards to be understood and managed when buying, building and operating private homes, residential and commercial developments, industrial buildings, and recreational facilities. This booklet provides information on the(More)
