Which pixel shader

Depending on the desired resolution, several million additional pixels may be required to shape and color an image at 60 frames per second. This requires increasing the capacity of the Graphic card. Take a look at the different versions of Pixel Shader, with the corresponding version of Direct X, for the main manufacturers, ATI and nVidia, but also for the integrated chips of Intel although its gaming capacity is limited.

Pixel shader inputs are interpolated from the vertex attributes of the primitive being rasterized, based on the interpolation mode declared. If a primitive gets clipped before rasterization, the interpolation mode is honored during the clipping process as well. Vertex attributes are interpolated or evaluated at pixel shader center locations.

Pixel shader attribute interpolation modes are declared in an input register declaration, on a per-element basis in either an argument or an input structure. Attributes can be interpolated linearly, or with centroid sampling. Centroid evaluation is relevant only during multisampling to cover cases where a pixel is covered by a primitive but a pixel center may not be; centroid evaluation occurs as close as possible to the non-covered pixel center.

Inputs may also be declared with a system-value semantic , which marks a parameter that is consumed by other pipeline stages. A pixel shader can output up to 8, bit, 4-component colors, or no color if the pixel is discarded. Pixel shader output register components must be declared before they can be used; each register is allowed a distinct output-write mask. Use the depth-write-enable state in the output-merger stage to control whether depth data gets written to a depth buffer or use the discard instruction to discard data for that pixel.

The depth value is output in the oDepth register, and replaces the interpolated depth value for depth testing assuming depth testing is enabled. Fragment shaders take a single fragment as input and produce a single fragment as output.

A Shader is a user-defined program designed to run on some stage of a graphics processor. Shaders provide the code for certain programmable stages of the rendering pipeline. They can also be used in a slightly more limited form for general, on-GPU computation. If the shaders option is not showing up, make sure to enable Optifine before launching. If you are using 1. If the downloaded shaders are not showing up in the list, most likely they are required to be extracted.
