Method, apparatus and system for performing texture sampling

Abstract

Use a shading language to implement texture samplers. The shader compiler is used to compile texture samplers to the target machine based on the sampler state, sampler operations, and other static element input values ​​provided to the texture sampler. Shaders such as vertex shaders, geometry shaders, pixel shaders, hull shaders, domain shaders, and compute shaders can call one or more texture samplers when calling shaders. One or more texture samplers, which are a piece of software code, can generate texture samples from texture data and provide such texture samples to a shader. Shaders use texture sampling to generate shading effects on graphics elements. Then, the graphic elements are rendered on the display device along with the shading effects.

[0001] This application is submitted on June 29, 2010, and the application number is a divisional application of the patent application with the same name as 201010220862.7. technical field

[0002] The present invention relates to texture sampling. Background technique

[0003] Texture generally refers to an image that includes a repeating pattern that can be used to wrap a graphic pattern. The texture data may be sampled using a texture sampling technique based on the Nyquist criterion. Texture sampling techniques are becoming more sophisticated and widely used. Texture sampling techniques may include: point sampling, bilinear filtering, trilinear filtering, anisotropic filtering, anti-aliasing, and other similar techniques. Texture sampling is increasingly used by eg vertex shaders, geometry shaders and pixel shaders.

[0004] Furthermore, the complexity and use of such texture sampling techniques has continued to increase, as has the complexity of the hardware used to...
