Dynamic computer graphics images are enhanced by mapping two-dimensional texture onto objects with texture definition appropriate to the range from an eye point to the object. With varying definition texture map levels stored, each carrying different texture resolutions (degrees of definition) select sets of levels are paged for mapping operations based on the range to an object. In an operation with two select sets, one set (the top) includes the five least detailed or least defined levels while the other set, the whole, constitutes all levels. The choice between the two select sets for texture mapping an object is determined based on the range, and a specific ratio of pixel view frustum values provides an effective test criteria.
