"In fact, as I recall, ALL the big players int he game immediately went to work developing their own systems to do so, and all o them bear a strong resemblance in the core methodology to what Poser does. Mostly becuase they did it first." I think Alias/Wavefront may have pioneered the rigging/IK technology for characters that is used in Poser. I do not think it was invented with Poser. In fact, I recall the original Hash Animation Master having a rigging system around the same time Poser 1 came out.
