PURPOSE:To display three-dimensional solid bodies which can be seen directly from all visual angles with respect to an object having optional size, shape, and materials, by heating a heat-sensitive material with two heating means which satisfy specific conditions. CONSTITUTION:The heat value given to a heat-sensitive material 1 by the first heating means 2-2' is lower than a threshold, and the heat-sensitive material 1 does not cause an optical unreversible change with only this heat value. The second heating means 3-3' has the same function as the first heating means 2-2' and generates a heat value smaller than the threshold not to cause an unreversible change in the heat-sensitive material 1. Heat values generated from the first heating means 2-2' and the second heating means 3-3' are added in an intersection P between heating means 2-2' and 3-3' which is indicated by a black point, and an optical unreversible change is caused in the point P if the addition value exceeds the threshold. Consequently, a three-dimensional object to be displayed and the heat-sensitive material displayed as solid bodies can be separated spatially from each other, and processing are performed in real time. |
