This paper presents a robust method for evaluating boolean operations on triangle meshes. It is based on a fast and reliable point-in-solid algorithm that works with B-Rep representations. With this method, several boolean ...

We propose to observe users spontaneous facial expressions as a method to identify adverse-event occurrences at the user interface level. We discuss an experiment designed to investigate the association between incidents ...

Human computer interaction techniques that do not rely on devices are often perceived as more natural by users. Many of these, include hand pose recognition as an interaction technique appealing to users. In this paper we ...

This paper present a simplified approach to wind animation of natural looking tree stems and branches. The presented approach is composed from several earlier works by a number of authors, each adapted to increase its ...

This paper describes the work of a new implementation of the Boolean operations of Blender. Blender is a modelling and animation 3D software with GNU General Public License (GPL). Boolean operations are a useful tool for ...

High-Fidelity rendering of complex scenes is one of the primary goals of computer graphics. Unfortunately, high- fidelity rendering is notoriously computationally expensive. In this paper we present a framework for ...

The usable perceived depth range of all stereoscopic 3D displays is limited by human factors considerations to a bounded range around the plane of the display. To account for this our Three Region stereoscopic camera model ...

There is a growing demand from the media industry, including computer games, virtual reality and simulation, for increasing realism in real-time for their computer generated images. Despite considerable advances in processing ...

Forest fire fighting is unfortunately a very important activity for many fire departments. A forest fire is always a very complex situation to manage, in which lots of ground teams and aircraft have to cooperate in order ...

This paper presents an automated approach to transferring facial expressions from a generic facial model onto various individual facial models without requiring any prior correspondences and manual interventions during the ...
