The evolution of medical imaging technologies and computergraphics is leading to dramatic improvements for medical training, diagnosis and treatment, and patient understanding. This paper discusses how volumetric visualization and 3D scanning can be integrated with cadaveric dissection to deliver benefits in the key areas of clinician-patient communication and medical education. The specific area of medical application is a prevalent musculoskeletal disorder-iliotibial (IT) band syndrome. By combining knowledge from cadaveric dissection and volumetric visualization, a virtual laboratory was created using the Unity 3D game engine, as an interactive education tool for use in various settings. The system is designed to improve the experience of clinicians who had commented that their earlier training would have been enhanced by key features of the system, including accurate three-dimensional models generated from computed tomography, high resolution cryosection images of the Visible Human dataset, and surface anatomy generated from a white light scan of an athlete. The finding from the virtual laboratory concept is that knowledge gained through dissection helps enhance the value of the model by incorporating more detail of the distal attachments of the IT band. Experienced clinicians who regularly treat IT band syndrome were excited by the potential of the model and keen to make suggestions for future enhancement.

Multi-spectral remotely-sensed data such as satellite imagery can yield excellent insights into complex phenomena such as weather systems. Analysing the multi-channel space to separate out different features still presents a challenge, which may increase with the availability of hyperspectral satellites. We use component labelling and population thresholding techniques to separate out clusters in hyper-dimensional channel space and use this information to identify different cloud types in geostationary satellite imagery. Three dimensional visualisation techniques are used to study the hyper-dimensional channel population data.

The increasing popularity for stereoscopic content in the entertainment industry and computergraphics applications and the availability of affordable capture and display systems is in contrast to the actual knowledge of underlying stereoscopic design principles and fundamental concepts. Content creators and educators inexperienced in stereoscopy require integrated, easy to use and flexible tools which can assist in the process of creating the three-dimensional "look" they are after within the limits of a comfortable viewing experience. The proposed framework in this paper, a custom stereoscopic export plug-in for the popular 3D modeling application Google Sketchup and a flexible stereoscopic format conversion and display engine, allows for stereoscopic pre-visualisation in near real-time in a format of choice. The user interface can recommend stereoscopic settings according to the scene, camera and display properties, calculates corresponding values according to manual entries but also leaves unrestricted control over all parameters. The display engine allows for different stereoscopic formats to be shown and saves the result in form of images with metadata for reference. Particular attention is put on usability, accessibility and tight integration.

Rapidly increasing urban populations are placing increased pressure on social, economic and environmental resources. For our cities to cope with this demand we must ensure that any growth is sustainable. Tools already exist which attempt to support sustainable urban decision making. However, as previous work by the authors shows, many of these existing tools fail to either adequately engage all possible stakeholders or represent fully all the complex interactions between the aspects of sustainability. This paper describes the underlying concepts of a prototype simulation and visualisation tool (S-City VT) that will allow all stakeholders, regardless of background or experience, to understand, interact with and influence decisions made on the sustainability of urban design. Using the Dundee Waterfront Development Project as a case study, S-City VT takes the unique approach of combining computer game technology with computer modelling to present the stakeholder with an interactive virtual development. Initial results highlight the viability of virtual representations of proposed real-world structures and also effectiveness of the specific visualisation techniques used in conveying urban sustainability information.

With the mindset of merging both aesthetics and technical knowledge to create believable 3D visualisation, a new set of refined Principles of Photorealism are applied to enhance the 3D rendering approach consequently creating realistic yet quick to create 3D visualisation for Interface Design. This paper discusses the importance of applying the principles with consideration of interface visualisation aspects towards the human environment and the interfaces within. This includes studies of depth, perspective and spatial studies in computer Aided Design (CAD) and Virtual Reality Added Design (VRAD) for Interface Design. The case studies selected emphasize on exact measurement and accurate mapping as well as lighting techniques for the most realistic output. The outcome of this study serves as a guideline to identify basic principles and elements of Photorealism to create efficient photorealistic 3D rendering in terms of model properties, textures, lighting and rendering.

In this paper we describe incorporating Einstein's Special Theory of Relativity into an interactive computer game intended for learning and teaching purposes in Australian senior high school and tertiary education. The game, which is based on \emph{Asteroids}, embeds either a classical or relativistic model of physics in the game environment such that players interact directly with the physics in the course of playing, and can observe and contrast their behaviour. The emphasis is on conceptual portrayal with 2D graphics, rather than immersive and realistic 3D visualisation. The key relativistic concepts of length contraction, time dilation, and mass dilation are each represented, as well as Doppler shifting of colour. We discuss design considerations and graphical devices for portraying these effects in the game, along with results and responses from user experiments.
