Embodiment Construction

[0013] The following description describes techniques for performing texture sampling using a texture sampler implemented in a shading language. In the following description, many specific details are set forth, such as logic implementation, resource division, or sharing, or replication implementation, types and interrelationships of system components, and logic division or integration selection, so as to facilitate a more thorough understanding of the present invention . However, one skilled in the art will recognize that the present invention may be practiced without these specific details. In other instances, control structures, gate level circuits and full software instruction sequences have not been shown in detail in order not to obscure the invention. Those skilled in the art, given the included description, will be able to implement the appropriate function without undue experimentation.

Abstract

A texture sampler is implemented using a shader language. The shader compiler is used to compile the texture sampler to a target machine based on sampler state, sampler operation, and other static factors input values provided to the texture sampler. The shaders such as a vertex shader, geometry shader, pixel shader, hull shader, domain shader, and a compute shader may call one or more texture samplers while the shaders are invoked. The one or more texture samplers, which are a piece of software code may generate texture samples from the texture data and provide such texture samples to the shaders. The shaders generate shading effects on graphics elements using a texture samples. The graphics elements along with the shading effects are then rendered on a display device.

Description

technical field [0001] The present invention relates to texture sampling. Background technique [0002] 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. [0003] Furthermore, the complexity and use of such texture sampling techniques has continued to increase, as has the complexity of the hardware used to perform texture sampling. There are at least some applications that may need to use texture sampling techniques that may not require or require direct access to hardware devi...
