My understanding of Poser JP bulges is pretty much complete at this time.  But there is one sticking point which will be difficult to determine:

Poser bases it bulge deformation on a simple translation in the direction of the midpoint of the blend zone (staticA/dynamicB=Left and dynamicD/staticC=Right).  The general formulation is that for a bulge value of 1.0 and a rotation of 360d, the greatest weighted point (at the midpoint with 1.0 weight) translates 1.0 along the direction previously noted.

The question arises as to whether or not this 1.0 unit translation is from the body part origin (irregardless of the point's distance from it) or in addition to the point's distance from the body part origin.  In most cases this probably will be insignificant, but it could play a great part otherwise - and it will definitely affect the weighting calculations that I'm updating.  Obviously, this also determines how much bulge is applied (how big the bulge gets) for any given rotation.

Appreciate any insights!
