Claim One:
1. A texture creation method performed by a computer comprising: arranging one or more three-dimensional texture objects in a space, and rendering the three-dimensional texture objects into a two-dimensional texture rendering area through hidden surface elimination processing performed by the computer while maintaining the depth of the three-dimensional texture objects from a fixed viewpoint with reference to the Z values thereof; dividing, by the computer, the two-dimensional texture rendering area in which the three-dimensional texture objects are rendered into a matrix with a plurality of mutually congruent texture tiles; and merging, by the computer, each texture tile into a predetermined target texture tile, wherein at the time of merging each texture tile into the predetermined target texture tile, the pixel data and Z values are updated based on the result of the comparison between the Z values of the overlapping pixels of the texture tiles, whereby the texture tiles are merged to create the intended texture data.
