A method and system for providing control that include providing a
workpiece that includes a target shape, providing a cutting tool,
providing a 3-D image associated with the workpiece, identifying the
target shape within the workpiece image, providing a 3-D image associated
with the cutting tool, registering the workpiece with the workpiece image,
registering the cutting tool with the cutting tool image, tracking at
least one of the workpiece and the cutting tool, transforming the tracking
data based on image coordinates to determine a relationship between the
workpiece and the cutting tool, and, based on the relationship, providing
a control to the cutting tool. In one embodiment, the workpiece image can
be represented as volume pixels (voxels) that can be classified and/or
reclassified based on target shape, waste, and/or workpiece.
