You think it is tricky to generate a complex 3D file now? Check out the first 3D rendered film created in 1972 by Ed Catmull (the founder of Pixar) and Fred Parke. Get some back story here. For deeper inspiration take a look at the Pixar Story that even helps make Steve Jobs look a little more human and a little less tyrannical.. Thanks Bart..
I love the line "polygons were drawn on the hand". I was curious about the computer too. Anyone have any ideas? I think I was using my Sinclair ZX81 shortly after that but I sure wasn't doing any nifty 3D programming!!
