Modeling device and association method
A modeling device capable of easily projecting characteristic information obtained from an object having even a complex shape onto another object having a different shape. The modeling device (1) comprises a virtual electrifying section (12) for measuring the potential at a given position in a heart when a predetermined value is applied to the heart and a projecting section (13) for projecting the fiber direction onto a heart model made according shape information inputted through an input section (10). The projecting section (13) specifies the position onto which the fiber direction is projected according to the potential measured by the virtual electrifying section (12). BY thus using the potential to specify a position, the fiber direction can be easily projected onto a heart having any of various complex shapes.
