摘要
There is provided a system and method for filter kernel interpolation for seamless mipmap filtering. There is provided a method of implementing a filter kernel interpolation for seamless filtering of transitions within a plurality of mipmaps derived from a base-image texture filtered using a prefilter, the method comprising choosing a filter kernel, determining a filter width for the filter kernel, selecting a first mipmap and a second mipmap from the plurality of mipmaps, applying interpolation on the filter kernel based on the prefilter, the first mipmap, and the second mipmap to generate an interpolated filter kernel, and applying the interpolated filter kernel to the first mipmap to generate a seamless filtered texture. Two alternative methods of interpolation are introduced, including filter kernel value interpolation and filter kernel position interpolation with x-lerping. By avoiding access to the second mipmap, greater efficiency and image quality can be achieved versus conventional interpolation.
