The purpose of this project is to develop new tools and resources that make use of 3D stereoscopic visualisation and investigate the new methods of teaching and learning that these tools enable.

 

The proposed solution is a combination of elements: low cost stereoscopic visualisation systems, a powerful volume rendering tool (OsgVolume) and an easy to use authoring environment (Present3D) that enables course materials, lectures and individual learning programs to be created.

 

Rather than view MRI/CT scan data as a series of individual slices, a volumetric program processes those slices and combines to create a complete 3 dimensional volume which can then be manipulated interactively. The use of stereoscopic visualisation gives true depth perception essential for understanding complex 3d data and volumetric data benefits greatly from this.   To work with the volume data interactively and in realtime a range of tools are required, clipping planes, adjustment of transparency of particular colours or luminance values, selection tools and others, so the area of interest can then be extracted or viewed as a complete entity within the overall volume, dramatically improving understanding of the actual shape, form and interconnectivity of, for instance, a brain tumour. Other more specific tools will be required to meet demands of the wide range of practitioners who will benefit from this project, but the first aim is to concentrate on the requirements for medical teaching and research, with use for patient information systems probably following.
