PROBLEM TO BE SOLVED: To provide a method and a device for visualizing a situation of a molding internal deformation to investigate workability and to elucidate a cause of a defect in a molding, in the working of a complicated shape of component plastically deformed three-dimensionally. SOLUTION: A modeling material is filled into a model die, using the modeling material with a deformation characteristic similar to that of a metal material embedded with a gage mark and is pressurized by a prescribed working amount, by a tool, and the gage mark is imaged concurrently by a radiation TV camera, by emitting a radiation from a single focal point. The model die is thereafter rotated around a model die center axis as an axial center, while bringing the model die for forming the parallax into a longitudinal direction of an imaging face of the TV camera as an axial direction, and the gage mark is imaged at a point therein, by the TV camera, by emitting the radiation from the single focal point. Those operations are repeated until finishing the pressurization, two-dimensional coordinates of the gage mark are computed based on an picked-up image, and three-dimensional coordinates are computed based on the two-dimensional coordinates constituting the parallax, to display superposingly a three-dimensional data of the gage mark and a shape data of the model die.
