# VkPipelineFragmentShadingRateStateCreateInfoKHR(3) Manual Page

## Name

VkPipelineFragmentShadingRateStateCreateInfoKHR - Structure specifying parameters controlling the fragment shading rate

Loading… please wait.

## C Specification

The `VkPipelineFragmentShadingRateStateCreateInfoKHR` structure is defined as:

    // Provided by VK_KHR_fragment_shading_rate
    typedef struct VkPipelineFragmentShadingRateStateCreateInfoKHR {
        VkStructureType                       sType;
        const void*                           pNext;
        VkExtent2D                            fragmentSize;
        VkFragmentShadingRateCombinerOpKHR    combinerOps[2];
    } VkPipelineFragmentShadingRateStateCreateInfoKHR;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `fragmentSize` specifies a VkExtent2D structure containing the fragment size used to define the pipeline fragment shading rate for drawing commands using this pipeline.

- `combinerOps` specifies a VkFragmentShadingRateCombinerOpKHR value determining how the pipeline, primitive, and attachment shading rates are combined for fragments generated by drawing commands using the created pipeline.

## Description

If the `pNext` chain of VkGraphicsPipelineCreateInfo includes a `VkPipelineFragmentShadingRateStateCreateInfoKHR` structure, then that structure includes parameters controlling the pipeline fragment shading rate.

If this structure is not present, `fragmentSize` is considered to be equal to (1,1), and both elements of `combinerOps` are considered to be equal to `VK_FRAGMENT_SHADING_RATE_COMBINER_OP_KEEP_KHR`.

Valid Usage (Implicit)

- VUID-VkPipelineFragmentShadingRateStateCreateInfoKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PIPELINE_FRAGMENT_SHADING_RATE_STATE_CREATE_INFO_KHR`
