Flexible delivery of visualization software and services [pdf] - by Jason Wood, Jungwook Seo, David Duke, Ken Brodlie and Jeremy Walton. An important issue in the design of visualization systems is the allowance of flexibility in providing a range of interfaces to a single body of algorithmic software. In this paper we describe how the ADVISE architecture provides exactly this flexibility. The architecture is cleanly separated into three layers (user interface, web service middleware and visualization components) which gives us the flexibility to provide a range of different delivery options, but all making use of the same basic set of visualization components. These delivery options comprise a range of user interfaces (visual pipeline editor, tailored application, web page), coupled with installation choice between a stand-alone desktop application, or a distributed client-server application. This work was carried out within the ADVISE project.
Flying Through the Heart - by Jeremy Walton. Scientists at Oxford University are building computer models of the heart to improve the diagnosis and treatment of cardiac disease. Experimental data forms part of the input to the models, and visualization of this data is required in order to better understand its structure. This article describes how the visualization was performed by one of NAG's Senior Technical Consultants as part of a consultancy project at the Oxford e-Research Centre. A detailed account of this work is available in this technical report [pdf].
A Web Services Architecture for Visualization [pdf] - by Jason Wood, Ken Brodlie, Jungwook Seo, David Duke and Jeremy Walton. Service-oriented architectures are increasingly being used in the creation of large distributed applications. This paper examines the provision of visualization as a service which can be made available for application designers to combine with other services. It describes a three-layer architecture which exploits the strengths of web service technologies in providing standardized access, and which also enables the efficient and flexible construction of visualization applications. A realization of the architecture is illustrated by re-visiting an early example of web-based visualization. This work was carried out within the ADVISE project.
Visualization For Public-Resource Climate Modeling [pdf] - by Jeremy Walton, Dave Frame and David Stainforth. Climateprediction.net aims to harness the spare CPU cycles of a million individual users' PCs to run a massive ensemble of climate simulations using an up-to-date, full-scale 3D atmosphere-ocean climate model. This paper describes the design and implementation of real-time visualization for the climateprediction.net desk-top package.
NAG's IRIS Explorer [pdf] - by Jeremy Walton. IRIS Explorer is a visualization toolkit which allows users to construct data visualization applications by connecting together software building blocks, or modules. This article describes the toolkit in some detail, including an account of how it can be used to build distributed collaborative applications with tailored user interfaces, its extension to the support of computational steering on the Grid, together with several examples of user applications.
