Abstract
A three-dimensional image rendering portion, based on image data, performs geometric transformation, projection transformation, etc. and further applies texture data from the texture memory onto polygons, to thereby generate graphic data of a 3-D image. This graphic data is used as pixel data for a frame of image and written into the frame memory. A 3-D texture modeling value generating circuit performs arithmetic operations on 3-D texture modeling values of asperities of the textures, using coordinate data given from the 3-D image rendering portion, bump data stored in the texture memory and parameters stored in the register. These 3-D texture modeling values are provided to 3-D texture modeling circuit where, based on these values, the data from the frame memory is formed into a 3-dimensional form, which in turn is displayed on the display unit.
