    摘要: A reconfigurable floating point data filter may be implemented by configuring a texture filter in response to state data, where the state data specifying at least a data width of input texture data to be filtered, where the input texture data is in a floating point format, filtering the input texture data using the texture filter, and then reconfiguring the texture filter to be substantially fully utilized when the data width of the input texture data changes.

    摘要: Apparatus, systems and methods for the simplification of 3D texture address computations based on aligned, non-perspective objects are disclosed. For example, a method is disclosed including receiving a texture address of a first pixel and determining a texture address of a second pixel by applying at least one offset to the texture address of the first pixel. Other implementations are also disclosed.

    摘要: A method, graphics processing unit, and system are described herein. The method for adaptive anisotropic filtering includes calculating a number of ways of anisotropy based on a computed level of detail of a texture map and applying a bilinear low pass filter to a texture map's closest two MIP maps using a processor. An effective number of ways and filter sizes may be computed on each of the closest two closest MIP maps. Additionally, the closest two MIP maps may be sampled at their respective effective number of ways. The method also includes applying a corresponding sized low pass filters to each of the closest two MIP maps, and combining the filtered closest two MIP maps using a weighted sum based on a fractional part of a computed level of detail.
