Currently the Interaction Data returns World Coordinates of hit position. If you have an interactive object with multiple "control surfaces" on them this is not as helpful as knowing relative to the center of the model what is the X,Y,Z Position hit was. I would want to know relative to the model did they hit a position how far left from the model center. Currently, because of returning world coordinates it is far from a simple calculation to determine what the relative position on the model is due to the fact the model could be rotated.
