چکیده
ions and Presentations. The PAC-C3D factory will give each Control one factory for Abstraction creation, and a list (which can be empty) of factories for Presentations creation, corresponding to each kind of existing Presentation on its node. If allowed by its distribution policy, then the Control will ask the Abstraction factory to create a real Abstraction. Next, the Control will ask each Presentation factory to create a Presentation. This is illustrated in Figure 3.11 for the creation of a PAC-C3D object on one node that is hosting two kinds of Presentations.

Collaborative Digital Architectural Design Learning within 3d Virtual Environments
This paper introduces a collaborative learning approach to digital architectural design within a 3D real-time virtual environment within which students Inhabit, Design, Construct and Evaluate (IDCE) their designs virtually and collaboratively. The paper articulates the development and implementation of the IDCE model utilized within the 3D virtual environment for achieving collaborative digital...

متن کاملService-Oriented Visualization of Virtual 3D City Models
Virtual 3D City Models Virtual 3D city models [1] provide means to communicate complex 2D and 3D geographical and geospatial data in an effective way (Fig. 2). Visualization systems that are based on 3D geovirtual environments (3D GeoVEs) serve as enabling technology in GIS and for manifold fields of application, e.g., as platform for presentation and communication of geodata (e.g., city market...
متن کاملA description of a dialog to enable interaction between interaction tools and 3D objects in collaborative virtual environments
Building virtual reality applications is still a difficult and time consuming task. Software developers need a common set of 3D widgets, hardware device abstraction and a set of software components that are easy to write and use. These means are intended to provide collaborative interactions in rich virtual applications, easy use of many input devices, and easy deployment on multi-sites for sha...
متن کاملA communication architecture for telepresence in virtual environments
In this thesis, we describe the communication architecture of the blue-c, a novel platform for tele-immersive collaborative applications enhanced by 3D video conferencing features. This communication architecture is required to handle data communication and distributed computing within the blue-c system. This comprises not only the functionality of common networking services and remote method i...
