Virtual Reality (VR) systems may be used with great effectiveness in applications such as urban planning, virtual tourism, cultural heritage and education. In fact, the VR systems allow the visualization and interaction ...

With the main purpose of studying the articulatory configuration of the European Portuguese (EP) sounds and to evaluate coarticulatory effects, a large 3D MRI database from several speakers and contexts have been acquired. ...

This work presents the results of applying several digital cartographic generalization techniques to improve the performance of an Electrical Power Grids Computer-Aided-Design application. The performance increase is ...

Most of the unsupervised image segmentation algorithms use just RGB color information in order to establish the similarity criteria between pixels in the image. This leads in many cases to a wrong interpretation of the ...

This paper presents a new real-time method to model and render how sprayed concrete is spread on a surface. The method not only models and renders deposits sprayed from any angle, any distance and with any concrete flow, ...

Traditional content creation for computer games is a costly process. In particular, current techniques for authoring destructible behaviour are often limited to a single object basis. In this paper, we build on previous ...

BlenderCave is a framework for the fast creation of virtual reality applications for multi-screen display systems. It consists of a set of extensions to the open-source Blender Game Engine (BGE), leveraging the scene ...

We describe a system for submission, automated validation and assisted evaluation of Computer Graphics' assignments. This type of assessments has a series of specific challenges associated to it, namely the analysis of ...

Automated debugging techniques, based on statistical analysis of historical test executions data, have recently received considerable attention due to their diagnostic capabilities. However, current automatic debugging ...
