Sadly, it has just been brought to my attention that Ralf Sessler, also known as Dimension3D or D3D, recently passed away. I am not exactly sure of the details.

Although I didn' t know him very well, I'm sure I am allowed to say that we have lost a legend, a friend, and one of the most helpful people in the 3D community. He was always ready to help. His products have been, without question, the most useful I have ever had the privilege of using. He will be missed terribly. My condolences to his friends and family.
