This work is associated with the construction of multi-media systems for scientific and rheological case-studies, introducing the element of interactivity. The base-data are often the end-result of simulation (CFD) or experimental investigations, utilised in some post-processing form, calling upon visualisation. Other issues addressed include the organisation and presentation of data, into meaningful and easily-accessible forms. This reveals multifaceted presentation requirements. In this respect, current commercial presentation applications have been found lacking. They rarely offer cross-platform compatibility, provide limited programmability, are restrictive on data-interaction, and only support static WWW-delivery. Hence, a substantive goal has been to deliver comprehensive multimedia-system functionality, both as a stand-alone system and over the WWW, via a single, multi-purpose implementation. A multimedia framework is employed, to embrace the interactive and visual presentation of a series of scientific and rheological case-studies with large conventional (static), and multi-mode (dynamic) data-sets. Graphs are utilised to enable rigorous multimedia system (MMS) design, effortless updates and unproblematic future expansion. Multimedia environments (MME) facilitate rapid prototyping and a data-oriented approach is advocated. As a result, the customised presentation-attributes vary widely from case-study to case-study, touching upon aspects such as user-interface, interaction, data-content organisation and presentation-styles. Case-studies include educational and scientific/industrially-related content. A film introducing the scientific area of non-Newtonian fluids is digitally constructed, using solid-modelling animations, simulation-data, filmed experiments, music, voiceover, and transitions. Content-delivery for multiple media is implemented, and includes interactive WWW or CD/DVD multi-language versions and static (videotape, DV) modes. Next, a historical multimedia (MM) presentation (History of Rheology MMS) is generated. This features an informal user-interface dynamic rendering of content, making extensive use of client-server technology for interactive stream-delivery over the WWW. Synchronisation is demanded for multiple streamed data-types, such as: voiceover, music, experimental and CFD-sourced data, animated-graphs, and rendered wire-frame graphics. Scientific/industrial data-sets of increasing complexity are featured.
