Interactive downloading huge virtual scenes on Internet is always a challenging task of large scale DVE(Distributed Virtual Environment) systems. Along classical progressive transmission mechanism based on AOI (Area of ...

In this paper, we show how to capture an actor with no intrusive trackers and without any special environment like blue set, how to estimate its 3D-geometry and how to insert this geometry into a virtual world in real-time. ...

The need for realistic models especially in virtual reality environments leads us to freeform shapes like subdivision surfaces. Based on a standard polygonal mesh, the modeller can build various kinds of shapes using an ...

Creating and setting the right parameters for the virtual camera is crucial for any content creation process. However, this is not easy since most current camera models, including the X3D Viewpoint, use a 3D position and ...

Last years, a new fashion over Internet and computer networks has been established: the 3D virtual worlds. Reports about Future Internet predict virtual worlds will play a major role in the configuration of the future ...
