1. A non-transitory computer-readable medium comprising program instructions operable, upon execution by a processor of a computer, to cause the computer to:
generate, based at least on a 3D model of a primary workpiece and a cut solution for the primary workpiece, a virtual model of a predicted flitch to be cut from the primary workpiece according to the cut solution, wherein the primary workpiece is a cant or a log, and the 3D model of the primary workpiece is based on a detected geometric profile of the primary workpiece,
compare a virtual model of an actual flitch to the virtual model of the predicted flitch, wherein the virtual model of the actual flitch is based on a detected geometric profile of the actual flitch and the geometric profile of the actual flitch is detected after the actual flitch is cut from the primary workpiece,
based on the comparison, identify the primary workpiece as a source of the actual flitch,
determine a difference between the actual flitch and the predicted flitch, and
send control instructions to a controller to cause the controller to adjust a cutting device, a cutting member, a workpiece positioning or handling device, or a workpiece transport based at least in part on said difference.
