Abstract
A first copy of an object is rendered using a texture sample selected from a texture image. This texture sample is selected from the texture image according to a first set of texture coordinates. The rendered object is stored in a frame buffer. Next, a second copy of the object is rendered using a second texture sample selected from the texture image. The second texture sample is selected from the texture image according to a second set of texture coordinates calculated in accordance with the first set of texture coordinates and one or more Jitter factors. The second set of calculated texture coordinates is displaced from the first set of texture coordinates along an axis of anisotropy. This second rendered copy of the object is then blended with the first rendered copy of the object to produce an object with anisotropic filtering. In embodiments of the invention, more than two copies of the object are rendered and blended together to form an object with anisotropic filtering.
