Method and apparatus for synthesizing a three-dimensional image signal and producing a two-dimensional visual display therefrom

摘要

A method and apparatus for formulating a picture and a household game playing apparatus are provided. Data necessary for formulating the picture are read from picture data of a three-dimensional object stored in a main memory (2), and coordinates (V) of apex points of relatively small-sized polygons comprising the three-dimensional object are produced by a geometry processor (61) for producing luminance data (L) and color data (D) for each apex point. Color data and coordinate data of boundary points between the apex points are produced by a raster processor (62). The raster processor uses the color data and coordinate data of the boundary points to produce color data and coordinate data of intermediate points between the boundary points.
