METHOD OF DISPLAYING IMAGE |
摘要 |
<p>A method of displaying graphic image surface information data of an object lying within a threedimensional space on a two-dimensional display screen when seen from a predetermined observing point is disclosed. A patch of the surface of an object is separated into plural triangular units, and image information data (luminance, visible-nonvisible, and distance) are all represented at the three apexes of each triangular unit area which includes a number of display pixels. The positional data at the three apexes are transformed from three- to two-dimensional space. The other image information data are calculated in accordance with interpolation calculation. Prior to the interpolation calculation a display area is determined and a triangular area including pixels to be processed is determined to reduce the processing time. This process is repeated for the entire surface to be displayed.</p> |
