Apresenta-se a implementação e adaptação de um algoritmo de 'Ray Tracing' a um sistema de modelação de objectos tridimensionais baseado em B-REPS.

Introductory computer graphics courses are changing their focus and learning environments. Improvements in hardware and software technology coupled with changes in preparation, interest, and abilities of incoming students ...

In environmental surveys a large sampling effort is required to produce accurate geostatistical maps representing the distribution of environmental variables, and the analysis of each sample is often expensive. Typically, ...

Recent hardware and software advances have demonstrated that it is now practicable to run large visual computing tasks over heterogeneous hardware with output on multiple types of display devices. As the complexity of the ...

We describe an adaptive particle-based technique for simulating incompressible fluid that uses an octree structure to compute inter-particle interactions and to compute the pressure field. Our method extends the hybrid ...

Adaptivity to scene changes is a main requirement for video analysis. The interpretation of video streams can be dealt by triggering different techniques depending on the scene properties. We present a work-on-progress for ...

In this paper, we present a novel method for refining correspondences between 3D point clouds. Our method is compatible with the functional map framework, so it relies on the spectral representation of the correspondence. ...

This work-in-progress paper describes some of the issues, and lists proposed use-case scenarios, for the development of a real-time multi-participant 3D enhanced videoconferencing system. We are interested in creating a ...

Nearly forty years since its conception, the medium of VR is still an enigma. In many ways, it is a medium that still lacks its own uniform language. VR, and particularly photorealistic VR, is a medium that is so occupied ...

Os agentes autónomos têm sido um tema importante de investigação nos últimos tempos, tanto nos ambientes virtuais como em automatismos destinados a operar no mundo real. No entanto, a maioria das aplicações a que se destinam ...
