Abstract

A real-time display type image synthesizing system which can display a 3-D object with less polygons and with high resolution is provided. The 3-D object data is stored in a 3-D object data storage unit 26 as shape models having different degrees of precision. The closer the 3-D object is to the view point in the view-point coordinate system, the object data of the shape model of higher precision is read out. Texture information applied to each polygon in each of the shape models is stored in a texture information storage unit 32 as image information of different resolution for every shape model and for every polygon in the shape models. An image forming unit 34 maps the texture information of precision corresponding to each polygon in the 3-D object perspectively projected and output by a 3-D calculation unit 22 onto the respective polygons to synthesize and display an image on a display 40.
