Abstract: Systems and methods include determining whether a parameter of a hogel beam, from a set of hogel beams, is within one or more thresholds. The one or more thresholds are based at least in part on one or more parameters of a first set of hogel beams. In response to the parameter being outside of the one or more thresholds, new values are determined for the parameter based at least in part on one or more parameters from a second set of hogel beams.
