This issue is a placeholder for the concept of defining other quantities in dyna3, that are not directly (say) the coordinates of any entity. For example, the sum of two lengths. One might want to observe such quantities, and if possible, constrain them. In short, it seems like in the ideal world, any formula in known quantities could act as a Regulator.

In particular, in modeling the Impossolid, if such a facility were present, an unset regulator for the sum of absolute values of differences of segment lengths would provide a readout of McNeill's distortion metric, with no additional coding needed.

And in the even better ideal world in which one could set such a regulator, setting it to 0 would directly correspond to attempting to minimize that distortion.
