So I am writing an exporter for my game and I need “relative from parent” bone translation and rotation,
I can grab these values using the constants PO_LOCX, PO_LOCY, PO_LOCZ, PO_QUATW, PO_QUATX, PO_QUATY, PO_QUATZ
as described in http://www.blender.org/documentation/244PythonDoc/Ipo-module.html but I am not sure what are those values relative to,
if there are only rotations all LOC values come up as 0, I though that means relative to itself, but now I am really wondering if these are rather deltas to be added to the original bone transform.
Am I right? what exactly do the IPOs return?
