In this paper, we describe 3WPS, a framework to builddistributed systems that are able to monitor and interact with a process via a 3d interface that is accessible via the World Wide Web. 3WPS is easily configurable, easily adaptable to different processes with high reuse of its software components and its distributed architect re leverages on off-the-shelf components of the infrastructure such as Java applets and VRML browsers.

3d medical images represent tremendous amounts of data. Grid technologies offer large anddistributed computing power suited to medical images analysis. However interactive programs with user supervision are made difficult on a grid architecture due to the remote program execution. In this paper we propose a new framework for interactive execution of remote applications dealing with large 3d medical data sets. Our solution is both efficient and easy to use from the user point of view.

A "Collaboratory" is a lightweight application component allowing project teams to collaborate and share data and insight while distributed over a network, using intuitive visual navigation techniques. The innovation can be summarised as the integration of network technology used in collaborative games with 3ddata navigation technique based on a low-level, fine-grained, customisable "atomic" visualization component infrastructure. In this paper we have focused on 3d medical imaging tools describing a Collaboratory implementation of a "Volume Viewer". This paper is also a blueprint to inform researchers and software engineers about the possibility to extend existing visualisation applications to support collaboration, e.g. making it easier to "collaboratize" visualization applications based on Microsoft's directX class library.

For the first time since computers are around, the major pieces of the puzzle are in place to deliver interactive 3d to the average end user. Yet, with the exception of games and some e-commerce applications, the take-up of 3d remains slow. This paper surveys current issues related to the potential of 3d for IST applications and gives an overview of activities most relevant to 3d research. The EUs 6(th) Framework Programme is also briefly discussed and orientations for the integration of imaging and3d research are proposed.

The general concept of virtual reality System supported by data gathered by means Of optical 3d shape measurement system is presented. The methodology, of data filtering, coding and streaming in order to perform real-time transmission of 3ddata into virtual reality is given. The concept of a virtual camera, as the mean for interactive object visualisation in VR environment is introduced. The details of data coding and filtering methods are given and their algorithmic implementation is described. The directions of future works focused on full implementation of the concept of hybrid experimental-numerical VR systems are discussed.

We propose a fast 3d model acquisition system that aligns intensity, anddepth images, and reconstructs a textured3d mesh. 3d views are registered with shape alignment based on intensity gradient constraints and a global registration algorithm. We reconstruct the 3d model using a new Cubic Ray, Projection merging algorithm which takes advantage of a novel data structure: the linked voxel space. Finally, we present experiments to test the accuracy of our approach on 3d face modeling using real-time stereo images.

The Virtual Boutique is an e-commerce environment based on virtual reality and content-based management Of three-dimensional information. The boutique and its content arc virtualized with laser scanners and photogrammetric techniques. Algorithms for searching the boutique inventory by three-dimensional shape and image content are described. Business rules are data mined from the interaction of the consumer with the boutique in a virtual environment.

We present a method for the reconstruction of a 3d real object from a sequence of high-definition images. We combine two different procedures: a shape from silhouette technique which provides a coarse 3d initial model followed by a multi-stereo caning technique. We propose a fast but accurate method for the estimation of the caning depth at each vertex of the 3d mesh. The quality of the final textured3d reconstruction models allows us to validate the method.
