Abstract: A modeling device is disclosed that easily projects characteristic information obtained from an object onto a differently-shaped object, even if the object, from which the characteristic information is obtained, has a complex shape. A modeling device in one embodiment of the present invention includes a virtually electrifying section to calculate an electric potential at a spot in a heart at the time when a predetermined voltage is applied to the heart, and a projecting section to project a fiber orientation onto a heart model created on the basis of shape information that is input to the input section. The projecting section specifies a spot to be a target of projection on the basis of the electric potential obtained by the virtually electrifying section. Use of the electric potential in specifying the spot makes it possible to easily project the fiber orientation onto any heart having complex and various shapes.
