Most of the current Demiurge 3D product visualisation skill set was acquired in an 'on-the-job' learning curve. Some years ago, a prominent client in the industrial manufacturing sector required a three-dimensional representation of an exploded view showing the component parts of one of their products (an example of a later project is pictured below). The delivery at the time was pretty amateurish but the client bought into it and has since had various other of their products modeled and rendered for educational and marketing purposes.
(The modeling above was not by Demiurge. We take credit for materials, lighting and rendering.)
