- Some Sample Data Visualisations -

The images shown on this page were created using the freely available 3D modelling tool - the Visualization Toolkit ( VTK ). The image below shows a visualisation of part of a MRI scan of a person's leg. Two isosurfaces have been extracted according to different densities of material encountered during the scan - muscle tissue (peach tone) and bone (white). A totally opaque sphere has been intersected with the skin isosurface actor as an implicit function so that the underlying bone can be seen. Click on the image for a small video of the objects.

The next image is a visualisation of wind behaviour in the upper atmosphere over the northern Polar region of the Earth gathered from a weather satellite in winter. The yellow-to-blue colouring represents temperature and the red arrows size and direction represent wind velocity at that position.
