Virtual spaces based on the metaphor of "shared network places" are becoming a well accepted implementation approach for multiuser, multimedia, distributed cooperative work environments to support the work activities and interactions of goal oriented business teams. Similar to real-life physical team rooms, which provide a permanent shared space used by a work group, TEAMWORKPLACE, the virtual ...

The theory and techniques for virtual acoustic modeling and rendering are discussed. The creation of natural sounding audiovisual environments can be divided into three main tasks: sound source, room acoustics, and listener modeling. These topics axe discussed in the context of both non-real-time and real-time virtual acoustic environments. Implementation strategies are considered, and a modula...

PURPOSE The aim of this report was to present an integrated 3-dimensional (3D) virtual approach toward cone-beam computed tomography-based treatment planning of orthognathic surgery in the clinical routine. MATERIALS AND METHODS We have described the different stages of the workflow process for routine 3D virtual treatment planning of orthognathic surgery: 1) image acquisition for 3D virtual ...

The main thing with the sub-class mechanism as found in languages like C++, SIMULA and Smalltalk is its possibility to express specializations. A general class, covering a wide range of objects, may be specialized to cover more specific objects. This is obtained by three properties of sub-classing: An object of a subclass inherits the attributes of the super-class, virtual procedure/method attr...
