Methods and apparatus to facilitate adaptive texture filtering

Abstract:

The present disclosure relates to methods and apparatus for graphics processing. In some aspects, the apparatus selects a first mip-map layer with a first texture size and a second mip-map layer with a second texture size based on a third texture size of an image. The apparatus also determines a relative distance associated with the texture sizes. Additionally, the apparatus determines a first quantity of samples to select from the first mip-map layer, and determines a second quantity of samples to select from the second mip-map layer, the second quantity of samples being less than the first quantity of samples, and a second quantity of filter taps being less than a first quantity of filter taps. Also, the apparatus generates the image at the third texture size through filtering based on the first quantity of samples and the second quantity of samples.
