International audienceIn scientific visualization data are becoming more and more complex and implies cooperative effort for their post-processing analysis as well as high performance processing resources. Moreover experts are frequently geographically distributed and existing post-processing tools do not provide high performance capability with collaborative features. To solve this limitation, a prospective action has been recently initiated in the frame of the ANR SCOS project, with the development of a web based post-processing framework called V3D. SCOS/V3D is based on two innovating concepts: the sharing of the processing results via the transfer of a X3D data file corresponding to the final virtual reality scene and communications based on HTTP to by-pass standard proxies and firewalls limitations. To test this approach, a proof of concept prototype, called shareX3D, has been developed, especially focusing on the events notification, with an implementation of the long polling technique. The architecture of ShareX3D and first tests are presented and discusse

CARRIOCAS project studies and implements in a test bed a very high bit rate (up to 40 Gb/s per wavelength) network tailored for distributed applications. The investigations covers 40Gb/s component, systems and networking; network architecture, protocols and algorithms with a particular focus on application-network cooperation; and remote high resolution collaborative visualisation and distributed storage of massive volumes of data.

This paper presents an innovative model-driven architecture enabling 3D web-based design processes in the field of large complex building (LBC) projects, such as power plant construction. This work was motivated by proposing new ways of achieving 3D CAD tasks not only for highly complex and temporary organization in the design stages but also for the whole lifecycle of such installations, which may last several decades. in this particular scenario, it is very important to share the right information with the right stakeholder at the right time, to maintain a high level of knowledge sharing. Taking into account these challenges, we propose a first implementation of interactive 3D CAD editing tools, based on the X3DOM technology and driven by a knowledge layer which utilizes a complete reference data and rules management system. To store the CAD models, a Macro-Parametric Approach has been investigated and a 3D server has been added to the traditional PDM (Product or Plant Data Management) to execute remotely complex CAD operations. This is a very promising start to deploy lightweight and smart web3D CAD editing services for the AEC (Architecture Engineering Construction) and power industries
