A little while ago I was asked by the department of Pathology at the University Medical Center Groningen to develop an interactive 3D model on the anatomy of a lymph node for an e-learning module. The e-learning module itself can be accessed by clicking on the blue button, which will take you directly to the e-learning module.
The model itself was based on elaborate sketches, which were then converted to a 3D model in Pixologic Zbrush. It was great fun to build, since there are hardly any good 3D references and the structures are really interesting. Have a go at navigating through the model below:
