Abstract:
1. A method for applying a rotational transform to a portion of a three-dimensional representation of an appliance for a living body, the representation being defined by an input plurality of coordinates stored in a processor circuit memory, the input plurality of coordinates representing a general shape of the appliance, the method comprising: receiving operator input identifying a coordinate location of a rotational axis about which the rotational transform is to be applied; receiving operator input of a constraint defining an extent of a transform volume within which the rotational transform is to be applied to the representation of the appliance, said constraint comprising first and second rotational constraints with respect to the rotational axis, said first and second rotational constraints defining an angular extent of said transform volume about said rotational axis; receiving operator input of a rotational transform magnitude; applying the rotational transform to the portion of the representation of the appliance within the transform volume to produce an output plurality of coordinates representing a modified shape of the appliance such that the general shape of portions of the appliance outside the transform volume remain un-modified by the rotational transform; and storing the output plurality of coordinates in the processor circuit memory.
