Methods, systems and computer program products for texturing a picture element of an image. These methods, systems and computer program products include blending texture values from a first texture map corresponding to a first level of detail with texture values from a second texture map corresponding to a second level of detail to create a textured value for the picture element. The blending of the two texture maps, however, only occurs if the magnitude of deviation of the level of detail corresponding to the picture element from a level of detail of the first texture map is greater than a threshold value. The threshold value may be selected based upon the perceptibility of differences between the level of detail of the picture element and the level of detail of the first texture map.
