PURPOSE:To accelerate the geometrical conversion and the plotting processing of a three-dimensional model by plotting minutely a man's gaze point and plotting roughly other area. CONSTITUTION:result of plotting by plotting processing parts 30, 31 based on a geometrical processing by each geometrical processing part 20, 21 is displayed by enlarging or superposing as it is in accordance with resolution of a display. For instance, in the case of a geometrical conversion of a peripheral visual field, it is converted to a device coordinate system of low resolution, a plotting processing is executed, and in this case, the part corresponding to the center visual field is not plotted, and on the other hand, in the case of the geometrical conversion of the center visual field, it is converter to a device coordinate system of high resolution by considering a fact that a detailed observation by a man is executed, and in this case, the plotting processing is executed by clipping only the part of the center visual field, and each of them is superposed and displayed. In such a way, the geometrical conversion and the plotting processing of a three-dimensional model can be executed at a high speed. |
