Interactive isosurface visualisation of scalar field data on the 3D stereoscopic display and virtual reality

These videos demonstrate different scenarios of isosurface visualisation of scalar field data. Engineering experiment often produces a large scale scalar field data that is stored in HDF5 files. The visualisation in the videos is the result of an interactive framework that is designed to be flexible in handling isosurface visualisation of various volume size on 3D stereoscopic display and virtual reality headset. Small isosurface (< 1 million data points) can be visualised interactively on the fly. Large isosurface (> 1 million data points) needs to be extracted and stored prior to visualisation.

The images show the screen capture of visualisation in virtual reality environment. The skeleton and skull images are proof of concept to demonstrate the flexibility of the framework in handling scalar field data from outside engineering (in this case, CT scan data).
