The present invention provides a dividing method taking, into consideration, memory access when determining vertices of polygons created through division in an image rendering apparatus for rendering a 3-dimensional image with polygons, in which a polygon is divided into smaller polygons in order to improve the representational power of an image. The image rendering apparatus according to the present invention can write pixel data for an image that is to be displayed to a frame memory in the unit of a predetermined number of pixels. The image rendering apparatus selects vertices of polygons created through division such that the vertices are at the first pixel or the last pixel in the writing pixel unit.
