My passion for art often put me in the position of the teacher.  A teacher who repeats himself.  Did I mention I was an adjunct art instructor for nearly 10 years?  These are some classic links and knowledge bits from gurus around the world.  Shout out to those who break their backs spelling things out for the next generation often lifting everyone and not asking for a thing in return.  I cut teeth in the Threedy forums starting in 2004 and eventually found myself part of Polycount in the early 2010s.  Thanks guys.  This list is forever WIP.
