摘要： PURPOSE:To make a display processing faster without increasing input labor by automatically identifying a less important substance in a picture, and automatically generating and displaying an omitted model in which the number of parameters and the number of dimensions are subtracted from a detailed model. CONSTITUTION:By tracing beams 5 passing through a screen 2 from a viewpoint 1 set on a three-dimensional space, a detailed model 3 to be the first three- dimensional model of the substance and an omitted model 4 to be the second three-dimensional model of the substance are displayed on a two-dimensional screen. Here, the omitted model 4 obtained by decreasing the number of parameters or the number of dimensions from the inputted detailed model 3 by means of algorithm is generated, first, the displaying is executed by the omitted model 4 in which an intersection can be easily decided, and further, the displaying is executed by the detailed model 3 only for the substance, which is largely projected on the screen 2 and is necessary for detailed information. Thus, the display processing can be made faster compared with a case in which the all substances are displayed by the detailed model 3, and since the omitted model 4 is automatically generated, a manual input can be made unnecessary.
